Update composer dependencies from command line
提问by applecrusher
I am currently working with symfony2 and I want to launch to download the libraries I need. I know the command in linux is "$ ./composer.phar update --dev"however when I run this in windows it prompts whether I should open the file with the windows explorer or not. I currently have composer.phar installed on windows but I am having trouble launching it. How would I be able to update my symfony2 folder with the dependencies I need. Thank you.
我目前正在使用 symfony2，我想启动以下载我需要的库。我知道 linux 中的命令是“$ ./composer.phar update --dev”，但是当我在 Windows 中运行它时，它会提示我是否应该使用 Windows 资源管理器打开文件。我目前在 Windows 上安装了 composer.phar，但我无法启动它。我如何能够使用我需要的依赖项更新我的 symfony2 文件夹。谢谢你。

The problem is that Windows don't know how to open .phar files. You need to execute them using php interpreter php composer.phar updateand the php interpreter(php.exe) must be accessible on PATH.
问题是 Windows 不知道如何打开 .phar 文件。您需要使用 php 解释器来执行它们php composer.phar update，并且 php 解释器 (php.exe) 必须可以在 PATH 上访问。
You could use command php -vto check if your php is accessible from command line.
您可以使用 commandphp -v来检查您的 php 是否可以从命令行访问。

First go to your work directory like if you have wamp then c:/wamp/www.
Then enter composer if you can see list of composer command then its good.
Now type "composer self-update".
