since the latest php fpm docker image update yesterday (https://hub.docker.com/_/php?tab=tags&page=1&name=fpm-alpine) my pipeline is broken because apparently PHP version 8 is installed instead of 7.4 as in my Dockerfile specified.
I am using this in my docker file:
FROM php:7.4-fpm-alpine AS ...
But according to my composer installs the container has PHP 8.0.13 running:
Root composer.json requires php 7.4.26 but your php version (8.0.13) does not satisfy that requirement.
Anyone an idea what is going on here?
As Jeremy Brooks already mentioned, Alpine released version 3.15 where composer requires PHP 8 (https://pkgs.alpinelinux.org/package/v3.15/community/x86_64/composer). Instead of installing composer from getcomposer.org another solution is to use Alpine 3.14:
FROM php:7.4-fpm-alpine3.14 AS ...
The alpine PHP images you reference do not include composer, so how are you installing it? If you are using apk to installer composer, it looks like the latest alpine composer package is pulling php8 in as a dependency, and this is causing your issue. What solved this issue for me was to install composer using the install script from getcomposer.org instead of using apk.
Assuming this is what you are doing, remove this from your Dockerfile:
RUN apk add composer
and add:
ADD https://getcomposer.org/installer ./composer-setup.php
RUN php ./composer-setup.php --install-dir=/usr/local/bin --filename=composer
RUN rm ./composer-setup.php
If composer is indeed included in your base image (unlikely), you could try uninstalling first:
RUN apk delete composer
and then add the above code to install it from the setup script instead.
Edit: adding the ignore-platform-reqs flag will probably get you past the error, but you are introducing a possible point of failure in the future if you have a composer package with a platform requirement. In that case, you won't know about the error until runtime. I would not recommend that approach. The method I posted above will install composer using the version of PHP already on the system and will not require risky workarounds.
I'm currently working on my docker-compose file to install laravel 8 with php 8.
I tested "php:7.4-fpm-alpine", and when I access the container I'm getting this version of php :
/var/www/html # php --version
PHP 7.4.26 (cli) (built: Nov 30 2021 08:21:51) ( NTS )
You can test it yourself :
docker container ls
docker exec -it <container_id> sh
php --version
I'm getting PHP 8.0.13 when installing "php:8.0-fpm-alpine"
Also I'm creating my laravel project using the composer image, I don't have php/composer installed locally. It's something you might have a look, because it could be quickly confusing ;-)
I had the same problem today...
Try:
composer install --no-scripts --ignore-platform-reqs
Fixed it for me.
Code and Idea are from
https://stackoverflow.com/users/564000/armin
A little context: I am new to docker and dont know of any best-practices yet. My task is to create a webservice based on php and i decided to use docker-compose for provisioning.
Because we are all fancy devs, we know - there is no way to build a php application without using composer these days.
My question:
Should i install dependencies in the build? So by adding this to my Dockerfile:
RUN cd /app && composer install --no-interaction --prefer-source --optimize-autoloader
Or should i install dependencies during development and build the container image with included dependencies?
I only know of one way NOT to do it: install dependencies locally on the dev machine and build the container afterwards. But how would the "best practice" look like?
And - because i am a newbee in this field - how would i run a "composer require some/package" for my app service container?
By the way
I also noticed a message "Do not run Composer as root/super user!" when building the container. I added COMPOSER_ALLOW_SUPERUSER=1 to my Env file (as seen here), but this message still appears.
Is it possible to NOT execute composer install as root in a docker container? Can i ignore that message?
Thanks in advance,
Philipp
For the moment i am working towards the following solutuion:
Development environment:
Add the whole src as volume:
volumes:
- .:/app
initial composer install command
docker-compose exec app composer install
install new composer package:
docker-compose exec app composer require some/package
The package will be installed via the container in your composer package directory (/vendor by default of course), the source code can be inspected in your ide, etc.
Production environment:
Only app state defined as volume, for example:
volumes:
- public/uploads:/app/public/uploads
add /vendor to .dockerignore
and run composer install during build
RUN cd /app && composer install --no-dev --no-interaction --optimize-autoloader
So you will have a pre-built image to deploy, but still be able to develop in a more agile way.
There are still two downsides in this solution, maybe someone has input for me:
1) build becomes kind of slow - it seems composer caching does not work properly
A solution (i dont know if this is possible in composer) could be a volume for the composer cache directory.
2) all packages created by docker are owned by root, so you can only work on those files/folders with sudo/root session.
I have no idea how to fix this properly. Maybe i could create a user with the name of the dev user for the development container and have this user run commands and php-fpm, etc... For production root would be okay i guess.
I am still very new to docker and open for better solutions, so i wont accept this answer.
UPDATED
To add new user in docker user in Dockerfile. as follows
RUN useradd -ms /bin/bash newuser
USER newuser
if you want to create home user too
WORKDIR /home/newuser
or
mkdir /home/newuser
if you want to back to root user, you can do like
USER root
two-sides-of-a-coin -
It is a good practice to do on building images period which I also do the same as you.
we will get latest update from public repositories but another side of coin is that we cannot ensure they are the same version as we develop.
you need to handle this by specifying exact version in composer.json (do not use ^, *).
I've been stuck at this for a few days. I'm using 1and1 hosting, and they have their PHP set up a bit weird.
If I use just php composer.phar install, then I'm using PHP 4.4.6, which is horribly insufficient. However, I can run php5.5 composer.phar install, get a little bit further, but it still fails because somewhere along the line, PHP is called again, but it fails, as it's using 4.4.6.
Is there any way to tell Composer to use the php5.5 command? Has anyone successfully gotten Composer configured on 1and1 hosting?
I'm trying to get Laravel up and running (which uses Composer). I've been able to do it on my GoDaddy domain, but not 1and1.
Ubuntu 18.04 case ... this run for me.
/usr/bin/php7.1 /usr/local/bin/composer update
Maybe this can't solve exactly your issue but probably it will help others who comes here from web search.
Just run the command to add below code to your composer.json file to set different PHP version:
$ composer config platform.php 8.0.7
"config": {
"platform": {
"php": "8.0.7"
}
}
On xubuntu I had php 7.2 as default. But needed to run composer with php 5.6.
So this worked for me:
php5.6 /usr/bin/composer
You always can use that way.
In project folder where you has composer.json file. Run the command
php7.4 /usr/local/bin/composer install
or
php7.4 /usr/local/bin/composer update
where php7.4 your specific version can be(php7.0, php5.5, php7.3 etc...)
where /usr/local/bin/composer path for system folder with composer
!!! you should have php7.4-cli
sudo apt-get install -y php7.4-cli
That way for linux/ubuntu user
Cheers ;-)
If you just need to get composer to ignore the version requirements, you can bypass using:
composer install --ignore-platform-reqs
composer is a PHP binary script and it's using Unix Shebang to define which interpreter for executing.
root#home:~# head /usr/local/bin/composer -n 5
#!/usr/bin/env php
<?php
/*
* This file is part of Composer.
*
/usr/bin/php7.1 /usr/local/bin/composer update
So if you're running composer without any specific option, it will use your PHP version at /usr/bin/env php (which is your default PHP)
We can have many versions of PHP inside your Linux and you can flexible use which PHP version for executing as you want like this way:
root#home:~# /usr/bin/php7.1 /usr/local/bin/composer update
Or just
root#home:~# php7.1 /usr/local/bin/composer
root#home:~# php7.2 /usr/local/bin/composer
root#home:~# php7.3 composer
...
To check & find all installed PHP packages, goto /usr/bin/
root#home:~# ls /usr/bin/ | grep php
php
php5.6
php7.1
php7.2
php7.3
php-config
php-config7.1
phpdbg
phpdbg5.6
phpize
phpize7.1
I too have a shared hosting account on 1&1 (ionos) and here's what I have had to do:
if you login as the root ssh account, you can create a ~/.bash_profile and add
alias php="php7.1"
alias composer="php7.1 composer.phar"
to it so that you can now use the commands you would normally use and it just works. (put composer.phar in your project folder root)
Then, make sure your laravel composer.lock file from your dev machine gets up to your project folder on 1and1 and run
composer install
Using this tip from #tobymackenzie: on shared hosts you really should just run composer install (not update!) from a composer.lock file you created on your own machine. That way the memory usage remains very low.
I still had STDIN issues with artisan commands so make sure you change the .env file to
APP_ENV=local
because having it set to production throws infinite STDIN warnings as it waits for you to type yes. At least on my account it does.
Hope this helps somebody.
In my case, Composer detected PHP version 7.2.6 but my actual PHP Version was 8.0.2 .So , I did the following steps and It was the solution for me.
Step 01:- Add below code to your composer.json file
"config": {
"platform": {
"php": "7.2.6"
}
}
Step 02:- Then, run the below command.
C:\xampp\htdocs\your project name>composer update
Try this approach
ea-php72 /opt/cpanel/composer/bin/composer
The existing answers partly do not answer the question, give suggestions that do not work or give bad advice.
The question stated:
However, I can run php5.5 composer.phar install, get a little bit further, but it still fails because somewhere along the line, PHP is called again, but it fails, as it's using 4.4.6.
Instead, I am here showing a way to test and verify the suggestions.
I wish I had a better answer myself but I am unsure what is the best solution. Personally I would go with a solution which make sure PHP is called with the correct version on the host (e.g. via an alias or setting the PHP environment correctly, running the entire operation inside a container or some other solution), regardless of Composer and add a platform php constraint.
If you don't run any scripts and just need the requirements to resolve the dependencies correctly config:platform:php would probably be your friend.
Let's say our default php version is 7.4 but our project requires 7.2.
Check your default PHP version
command line:
# shows version of default PHP
php --version
# show path of default PHP
which php
# show version of /usr/bin/env php
# /usr/bin/env php --version
Create a test script in your composer.json
"scripts": {
"php-version": "php --version"
}
Now you can test what version of PHP is used for the commands Composer
calls, e.g.
composer php-version
/usr/bin/php7.2 /usr/bin/composer php-version
In my case, both of these use my default php script (which is version
7.4). So, while the 7.2 version is used to run Composer, the scripts
called by Composer use the default command (unless you use #php instead of php1).
Now let's add the platform setting as suggested in some of the answers
"config": {
"platform": {
"php": "7.2.0"
}
}
Does not change anything for the script execution:
/usr/bin/php7.2 /usr/bin/composer php-version
# result is still 7.4
Actually, what the platform option is important for is resolving the requirements, so you should add it (in your project composer.json). It just won't solve the above problem of composer using PHP with the correct version. See also Composer docs for platform.
If you use #php instead of php, then Composer uses the PHP_BINARY2 path which is the php binary path that Composer tried to infer being executed with. See Executing PHP scripts. In this example commonly $(command -v php7.4) different to $(command -v php7.2), here $(command -v php).
PHP_BINARY is an environment variable Composer sets for its own environment (ref), similar to the predefined PHP_BINARY constant in PHP.
I had the same issue and this is how I was able to figure out how to run composer using a different PHP version on a shared hosting without breaking the system :)
Luckily, solving this issue with composer using different PHP version is dead simple.
Findings:
Default PHP was not run from /usr/local/bin or similar folder. Using the
which php
or
whereis php
would not give you the best answer.
Follow the short guide below:
First find the actual path to your composer binary itself.
On my shared hosting server, it was at
/opt/cpanel/composer/bin/composer
I believe most hosting providers using cPanel would have such path to composer.
Next, create an alias to the PHP version you want to use.
In my project, I needed php 7.4 or newer.
As mentioned earlier, the host was using cPanel and the actual default PHP version that the server uses is in the path /opt/cpanel/
You should see different versions of php in the /opt/cpanel/ (prefixed by ea-phpxx) for example, for php 7.4, it would be a folder called ea-php74 and for PHP 8.0, it would be a folder called ea-php80.
Now, be sure that php exists in a path similar to this:
/opt/cpanel/ea-php80/root/usr/bin
If you find php in the folder, then you can now alias it as folows:
alias php='/opt/cpanel/ea-php80/root/usr/bin/php'
Test that the alias is working by running
php --version
and check the php version as shown in the screenshot below:
Now, run composer as normal. For example
php /opt/cpanel/composer/bin/composer update
php /opt/cpanel/composer/bin/composer install
php /opt/cpanel/composer/bin/composer install
Remember how we found the composer binary at /opt/cpanel/composer/bin/composer. If this does not match the path to the compser binary on your server, use the appropriate one.
I hope this helps.
Happy Coding!
You could change your PATH to override the php version.
PATH="/home/user/bin:$PATH"
In /home/user/bin (or any other directory really) make a symlink named php to the php5 binary.
Another option, use a shell alias:
alias php="/path/to/php5"
I'm on a Hostgator shared account, the following worked for me:
First, find out where your desired version of PHP lives (you can start typing ea-php and hit TAB to list all available executables starting with ea-php):
which ea-php73
/usr/local/bin/ea-php73
Then, find out where composer lives:
which composer
/opt/cpanel/composer/bin/composer
Then use those to run your composer command:
/usr/local/bin/ea-php73 /opt/cpanel/composer/bin/composer install
For people using Plesk, you need the different pieces:
Get the PHP version required from /opt/plesk/php/<version/bin/php, eg /opt/plesk/php/7.4/bin/php
Get the real path of composer since /usr/local/bin/composer is a custom Plesk script by vieweing the script contents ( cat /usr/local/bin/composer ). In my case, it was /usr/local/psa/var/modules/composer/composer.phar
Put it all together:
# /opt/plesk/php/7.4/bin/php /usr/local/psa/var/modules/composer/composer.phar install
... or to make it simpler, just create a new file ( I like composer74 ) in /usr/local/bin:
cat > /usr/local/bin/composer74 to create the file
paste the following:
#!/bin/bash
/opt/plesk/php/7.4/bin/php /usr/local/psa/var/modules/composer/composer.phar
insto the terminal
Hit CTRL+D to save the file
chmod +x /usr/local/bin/composer74 to make it executable
Use it anywhere:
# composer74 install
Know this question is a bit old... but if you pull down composer into your app root:
https://getcomposer.org/download/
Instead of relying on global composer, then you can run:
php56 composer.phar {your command}
or I believe newer homstead versions would be like:
php7.1 composer.phar {your command}
https://laracasts.com/discuss/channels/laravel/run-composer-commands-with-different-php-versions
Ubuntu 18.04 case ... this works for me. Here, Composer picks the required PHP version automatically.
/opt/lampp/bin/php /usr/bin/composer install
OR
/opt/lampp/bin/php /usr/bin/composer update
php5.5 composer.phar install fails because your composer.json is telling it to run php and not php5.5, edit the file composer.json replace the php scripts references to php5.5. Example:
From:
"post-root-package-install": [
"php -r \"copy('.env.example', '.env');\""
],
To:
"post-root-package-install": [
"php5.5 -r \"copy('.env.example', '.env');\""
],
Even when doing this, 1and1 has a memory limit for scripts execution so php5.5 composer.phar install won't fail but it won't complete its execution either. You can still run the scripts post install manually.
I have deployed Laravel webapps to 1and1 without commit vendor directory, following this guide: Deploy Laravel Webapp to 1and1
I had no luck with any of above answers, I had auto scripts in composer.json so just ignoring or faking platforms just caused failed scripts etc. Setting php version in command just didn't work!
I did notice however that although running which php and php -v returned correct version which /usr/bin/env php returned the problematic version of php that composer was using. So found a very good answer here and outlined below:
Issue:
/usr/bin/env php looks for an executable named php in the current $PATH; it pays no attention to aliases, shell functions, etc. If you want it to execute php v5.3, you have to put that version in a directory under the name php, and put that directory in your PATH somewhere before the directory that contains the problematic version.
Fix:
Create new php executable folder like below with your specific php executable linked inside:
mkdir /usr/local/bin/php-overrides
ln -s /usr/local/bin/php7 /usr/local/bin/php-overrides/php
Add below to your ~/.bash_profile (or other appropriate startup script):
PATH="/usr/local/bin/php-overrides:$PATH"
https://serverfault.com/questions/579956/alias-doesnt-work-in-script-with-usr-bin-env-php
There are two ways to do it.
Tell the composer to ignore the platform requirements while running the command in the terminal.
composer update --ignore-platform-reqs
Tell the composer to ignore the platform requirements in the composer.json file in the project root directory.
"config": {
"platform-check": false,
},
We can tell Composer, what version of PHP we are supporting with our app by using the platform configuration in our composer.json file by adding the following configuration,
{
"config": {
"platform": {
"php": "5.5"
}
},
"require": {
...
}
}
Or from the command-line
composer config platform.php 5.5
i have a method to slove this problem.
export PATH=/usr/local/Cellar/php/8.0.12/bin:$PATH && composer -vvv
Temporarily change environment variables and use composer
With PHP 8 and 8.1 coming out, I have to work with a couple of versions regularly in the CLI, and the best way I found to do this was to create an alias.
Assuming you installed using brew, or already know where your version of PHP is.
Add the following to your bash profile.
alias php7='/usr/local/opt/php#7.4/bin/php'
alias php8='/usr/local/opt/php#8.0/bin/php'
If you want you can install PHP 8.1 as well with brew install php#8.1 and add another alias.
This will allow you to run php8 composer, you can do a quick test by creating an index.php file and adding phpinfo() to it.
php7 index.php | grep "PHP Version"
php8 index.php | grep "PHP Version"
While trying to install a Laravel application on my SiteGround shared hosting using SSH, I had to specify the adequate PHP bin constant prior to executing composer :
PHP_BIN=php81 composer install
Other solutions here would not work.
Must add in two places in your composer.json file to set different php version:
"config": {
"platform": {
"php": "7.4"
}
}
"require": {
"php": "^7.4",
}
You could try and copy the php and php-config files into /usr/local/bin instead. That path has a higher order of precedence and should override the /usr/bin folder without needing to disable SIP. That is what I did.
On AlmaLinux with php74 my default PHP version, php81 installed to /usr/bin/php81 and composer in location /usr/bin/composer, the following works one time: running composer using php81.
/usr/bin/php81 /usr/bin/composer install
Composer flags can be added as following:
/usr/bin/php81 /usr/bin/composer install --no-dev --no-interaction --ignore-platform-reqs
Notice these commands need to be executed from you working folder.
