I was testing using Propel for web application development, but bumping into some obstacles in the very installation of Propel.
As exposed in their documentation (http://propelorm.org/documentation/01-installation.html), I don't think any method other than Composer will work in sucessfully installing Propel. I tried with Github, but the result was an error when checking the validity of the installation: Could not open input file: propel
So I focused on Composer, and the same error when following Propel documentation commands $ php composer.phar install Could not open input file: composer.phar
Well, turns out that their documentation don't expose the correct syntax to run Composer with Windows CMD. Also Composer documentation doesn't expose that, neither (or I just couldn't find that).
So I deleted previous propel files, and tried just composer install, with composer.json file set up, of course.
And it worked fine!
Hopes this helps someone struggling with this.

apparently composer is having problems understanding version definitions. after installing composer using the official guide here: https://getcomposer.org/download/ i tried stuff like composer install or composer update, but every command returns the following error message:
Could not parse version constraint >=7.4.*: Invalid version string "7.4.*"
php version: 7.4.28
composer version: 2.3.5
i did not set up composer for this project, i just want to add a library. usually i just download the php files directly as this is far more efficient, but someone decided this project needs to use composer and now we are in this mess.
does anyone know what the problem is?
Afaik just 7.4 works - and from my logical assumption this should also include 7.4.* ;)
I am trying to install Symfony on CentOS Linux wih PHP 5.6 and cPanel installed.
When I run composer require symfony/assetic-bundle , once adding bundle to the AppKernelphp, symfony (app/console too) stops working and keeps logging this error:
[10-Jun-2016 22:00:57 UTC] PHP Fatal error: Class 'Symfony\Bundle\AsseticBundle\AsseticBundle' not found in /home/avid24/public_html/app/AppKernel.php on line 19
After checking the vendor directory, turns out that composer has downloaded a single compressed file with a random name, I could extract it with unzip. but problem still exists!
This environment works properly on windows and I could easily update symfony and its components using composer.
Any help? Anyone with the same experience ?
Well, I eventually figured out the problem!
I enabled suhosin extension which prevents the composer and other similar command prompt php scripts from a proper execution.
As a temporary solution I copied php.ini and disabled unnecessary extensions and put it next to my project and call composer this way
$php -c ../composer-php.ini ~/composer ......
I'll create a script to make the life easier
I didn't find any resource which describes coexistence of composer and suhosin extension, so I'm not sure if this is the ultimate solution but the root cause is identified.
If anybody makes workaround this subject I'd be more than happy to know about it.
I am Using my own Machine Kali Linux 2.0 Debian x64 . Now, i have Installed Laravel in my directory structure like
/opt/lampp/htdocs/learning-larvel/
Inside the Learning-laravel folder i have Installed my Laravel files, and also i installed composer. So when i go to http://127.0.0.1/learning-laravel/public . I see a See a White Screen and in Between it is written "Laravel 5", which means the Laravel GUI Setup is fine.
Now, to create a new file for Laravel, when i open my Terminal and type
laravel new xyz
then it gives me a error which says bash: laravel: command not found
Now, how can i fix the error.. I have researched about it by setting PATH to bashrc. But i am not getting it fixed right. Additionally when i type in my command composer -version then also it says bash: composer: command not found but i have Installed composer on the folder learning-laravel itself.
I could also see files like composer.phar there in /opt/lampp/htdocs/learning-larvel/
Any help would be extremely thankful.
As the composer official getting started page points out:
There are in short, two ways to install Composer. Locally as part of
your project, or globally as a system wide executable.
if you wanna do composer -- or laravel -- in command line, you wanna install them globally.
Check out the following links:
https://getcomposer.org/doc/00-intro.md#installation-linux-unix-osx
https://laravel.com/docs/4.2#install-laravel
I encountered the same problem. Apparently, the composer exists in path ~/.config/composer/vendor/bin when running as super user. Therefore, replacing the paths which were described above by this, and it should work. Hope it helps.
I just started my laravel course with laracast. I dont quite understand yet all the enviornment-related things.
I know that Composer is a kind of a program that downloads pre-written scripts to use in your project. But where does it work? On my local machine or on my vagrant homestead box VM? On which of these is it supposed to be installed?
I installed myself vagrant homestead box already but does it contain composer? When I go ssh into my guest machine and go to vagrant#homestead:/vagrant$ path I can see composer.json and composer.lock files, but does it mean that I have composer installed?
Composer is a PHP package manager, like npm for javascript or pip for python. There are many examples of package managers. It's useful, because adding dependencies to your php projects can be a pain, but composer makes it really easy. You just add the dependency to composer.json and you can use it right off the bat.
Composer isn't laravel specific, you can use it in any php project, laravel uses it to manage it's dependencies, laravels dependencies use it to manage their dependencies and so forth.
If nothing else, the composer autoloader is great, so you can use it even if you don't plan on using external packages.
Homestead should come with composer installed. A composer.lock file is generated when you run a composer install or composer update. If you plan on creating or using other php projects on your machine, it's probably a good idea to have composer installed on your machine as well.
I've installed the latest version of CakePHP, then installed PHPUnit using PEAR and tried to get access using such link as
http://localhost/[project_name]/test.php
But as a result I've got a message that PHPUnit is not installed. I can't understand what the problem is. Are there any other ways to solve this problem ?
And is it possible not to install PHPUnit, but just copy all its files to, for example, Vendor directory of CakePHP and to use it locally just for one separate project ?
I disagree with Mark. :)
The most easy way to install phpunit systemwide is using composer as described on their installation page:
For a system-wide installation via Composer, you can run:
composer global require 'phpunit/phpunit=3.7.*'
The easiest way in Win is https://github.com/dereuromark/cakephp-phpunit
That is standalone and will all work out of the box with
cake Phpunit.Phpunit install
It has no dependencies outside of CakePHP itself. No composer, no pear no other 3rdparty issues.
If you do have one of those dependencies available, use that one, though.
Note:
As of now the pear channel has been shut down and as such there is only the composer solution to it now. (See other answer)
