Composer 无法下载文件
我正在尝试在命令行上使用作曲家:
I am trying to use composer on command line :
php composer.phar update
php composer.phar install
php composer.phar self-update
php composer.phar selfupdate
无论我做什么，我总是收到相同的错误消息:
Whatever I do I always receive the same error message:
无法下载文件.打不开直播
File could not be downloaded. Failed to open stream
我支持代理.如果我使用浏览器并键入与不能使用命令行的 URL 相同的 URL，则没有问题.
I am behind a proxy. If I use a browser and type the same URLs as the ones that didn't work with command line, there is no problem.
我该怎么办?
推荐答案
如果你在 HTTP 代理后面使用 composer，你可以使用标准的 http_proxy 或 HTTP_PROXY环境变量.只需将其设置为代理的 URL.许多操作系统已经为您设置了这个变量.
If you are using composer from behind an HTTP proxy, you can use the standard http_proxy or HTTP_PROXY env vars. Simply set it to the URL of your proxy. Many operating systems already set this variable for you.
例如:
HTTP_PROXY="http://my-corp-proxy.mcdonalds" php composer.phar install
如果您在 Linux/OS X 或 Windows 环境设置中将其放入 bashrc，则会获得奖励积分.
bonus points if you throw it into your bashrc if your on Linux/OS X or your environment settings for Windows.
为方便起见，您只需导出变量，就不必一直键入它.
To make it easier, you can just export the variable, then you don't have to type it all the time.
export HTTP_PROXY="http://my-corp-proxy.mcdonalds"
php composer.phar install
