Let me start off by saying I'm completely new to Laravel and I would say I'm a beginner at PHP given how long it's been since I last did any PHP development. I'm running Mac OS X Yosemite (10.10.2) and I've installed AMPPS 3.0. I have installed composer and Laravel (as per instructions found here) as well. Now when I try to install Laravel on AMPPS (via http://localhost/ampps) I get the following messages:
The following errors were found :
Could not download composer.phar
Could not install composer
Could someone please enlighten me as to why this is happening? Also is this step necessary since I already have Laravel installed on my mac?
Short answer: I have no idea.
Long answer: I found this link when i was having some trouble with this myself.
Basically what's missing was adding the ampps php path in the bash file.
export AMPPS_PHP=/Applications/AMPPS/php/bin
export PATH="$AMPPS_PHP:$PATH"
Then, moving composer to user/bin directory with
sudo mv composer.phar /usr/local/bin/composer
I just included the big parts of what was missing in my case. Then install laravel as normal.

I want to use latest stable laravel 8.0 version for windows. but I cannot install using cmd. I want to crate new laravel project so I tried with this command which is available in laravel documentation.
cmd command .
composer create-project --prefer-dist laravel/laravel:^8.0 blog
Hope this helps : https://www.sitepoint.com/how-to-install-php-on-windows/ .
Download the PHP 8 using command and do the needful configuration.
What you are trying to do is run a composer script in a PC which does not have PHP installed.
First, download PHP from here;
PHP Windows download
Then, install composer from here;
Composer installation instructions
Both links have instructions on how to proceed with the installations. After you do both these, you can run that composer command in the command line.
I hope you know that composer is a dependency manager and PHP is the interpreter of the language. Happy coding.
I have been writing laravel code for quite sometime. Currently, I tried cloning a project from github and editing locally. I installed composer in my project directory but a vendor folder was not included, I tried to run composer install but I gives me this error
Your lock file does not contain a compatible set of packages. Please run composer update
How do I resolve this?
Note: I have tried running composer update on previous clones and that didn't work.
Run this command:
composer install --ignore-platform-reqs
or
composer update --ignore-platform-reqs
Disclaimer, this solution will not fix the issue for PHP 8 projects.
In most cases this happens because of PHP 8 (In my case it was GitHub CI actions automatically started using PHP 8 even though my project is php 7.4)
If you have multiple PHP installations (E.g. 7.4 and 8 on the same server), this is how you can fix it.
Specify your php version in your composer.json file
"config": {
"platform": {
"php": "7.3"
}
},
If you have the lock file already committed, run composer update after you adding above line in to the composer.json and then commit the new lock file. (Please be aware composer update will upgrade your packages to latest versions)
I solved this problem with this command:
composer self-update --1
It probably works because at time that the project was developed, composer was on another version and when change the Major version from 1 to 2 the compatibility was broke. With this command you downgrade composer and probably going to solve this
You should try running composer update --lock that will update all packages and recreate the compose.lock file.
Either you can delete the composer.lock file and run composer install that will also recreate the .lock file.
This resolved my issue.
I had this error with Github Actions trying to deploy a Laravel app, this is probably different than the OP's case but none of the suggestions worked for me. Adding my answer here just in case there is someone else out there with a similar problem to mine.
I had to disable -q in Github Actions and see that it was complaining about extensions not being installed.
Make sure your require section of composer's php extensions matches the extensions: in your github action file for shivammathur/setup-php#v2 and it will deploy again
Recently I've just come across of this error when I tried to run my Laravel 7 project which required php v7.* with php v8. As I forgot my php version I just tried bunch of composer command, but just got error after error.
Anyway, to solve this just downgrade/upgrade php version as required. Just search how to do that in youtube.
you can see your project required php version in composer.json file (just if you wonder)
Also you can try following way (But though it didn't worked for me, seems it helped quite some people)
-- Open composer.json file and change php version to something like this: "php": "^7.3|^8.1"
-- Then run composer update
I faced this problem with my cakephp project in garuda linux (arch based)
Fix :
Install php-intl using sudo pacman -S php-intl
Enable php intl by editing php config ( in my case /etc/php/php.ini ) .
add extension=intl or uncomment the existing one
restart apache or whatever you are using
I had the same error deploying another project with composer, but the problem was a missing php extension.
I understand you solve your problem but for anyone seeing the same error message, here is a general guidance :
The error message Your lock file does not contain a compatible set of packages. Please run composer update is shown each time there is a conflict during the dependency solving step of composer install. (see the relevant part in composer source code)
It doesn't inform on the real problem though, and it could be hard to guess.
To get the exact explanation you can add --verbose option to composer install command (the option is available to any composer command (see the doc)) : composer install --verbose
It will give you the full message explaining what exactly is preventing composer install from completing (package version conflict, missing php extension, etc.), then you'll be able to fix the problem.
Hope this could help.
In my case this problem is occuring in Ubuntu 20.04 Desktop. This is due to some missing packages.
I ran the following commands to install some packages then rerun Composer install and its working properly. The commands are:
sudo apt-get install php-mbstring
sudo apt-get install php-xml
Then rerun composer install
Hello I am trying to install symfony on Windows. I had follow the all require steps for it but it end up with below message.
[RuntimeException]
Symfony can't be installed because the downloaded package is corrupted.
To solve this issue, try executing this command again:
Symfony new demo 3.2.8
When i tried above command it says :
'symfony' is not recognized as an internal or external command,
operable program or batch file.
I have try to reinstall composer and Symfony package both but it does not resolve the issue. It stays the same issue again.
Please help me how can I install it on Windows.
You are required to make it run through PHP as its a script file.
This gets the installer (which it looks like you have already)
php -r "readfile('https://symfony.com/installer');" > symfony
Then php symfony new demo 3.2.8 (asuming if php is in path otherwise you have to specify the php.exe path too)
For the full details see http://symfony.com/doc/current/setup.html
Regards
forget about that installer use composer from command line
composer create-project symfony/framework-standard-edition my_project_name
BTW i don't know what server you are using (wamp/xamp etc), i recomending this
https://laragon.org/
it have composer and all tools that you need to start with symfony
i am lost...
i am trying to do it the right way and am following the Quick Start Guide for installing cakePHP 3 on my ubuntu machine.
Got composer installed. Directory is /var/www/cakephp
and am trying to issue:
php composer.phar create-project --prefer-dist cakephp/app mayapp
or
composer create-project --prefer-dist cakephp/app may app
then i am simply getting:
[InvalidArgumentException]
Could not find package cakephp/app with stability stable.
i do not have a clue what i am doing wrong. Any suggestions?
cakephp/app exists on https://packagist.org, and the command looks ok to me.
Which PHP version are you using? That package is only available with PHP 5.4.16 or later, so you must update if you want to use CakePHP.
However, it is a good idea to only use the same PHP version of your public hosting, using a newer version will lead to problems when deploying your code. If your webspace or public server does not have the latest PHP 5.6 running, ask for an update.
I got same issue. But, as previous answer, myapp does not exists on packagist.org, so, you must use laravel/laravel instead, and, after created, rename the new laravel folder to your desired name and move to htdocs (for xampp) or www (for wamp), then, and I do not know why, go to : localhost/laravel/public/
and replace laravel with the name you gave to your project folder instead the laravel one.
You will see Laravel 5 fonts will appear on screen.
That's means Laravel is running.
Hey Please try these steps.
Download XAMPP Server.
Install XAMPP server.
Go to ..\xampp\php\php.ini and open.
Add this line (extension=php_intl.dll) or if exist uncomment.
Download Composer setup from https://github.com/composer/windows-setup/releases/
Install composer and give php.exe file in path
Open cmd and check now php version using command php -v. if its showing php version its means its working.
Now open cmd and cd on xampp\htdocs folder & run command composer create-project --prefer-dist cakephp/app app_name
Finished folder created in htdocs.
Hope this is helpful for you.
There are many documentation about how to install Zend Framework 2. But they are hard to understand. I've tried lot of guidance in the web. But still I couldn't install ZF2.
This might be a duplicate question. But I went through most of them and ended up with no success.
Can any one please give me the simple step by step installation guidance?
I'm using XAMPP on windows 7
Thanks a lot
