Composer cannot download files

Question

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

Whatever I do I always receive the same error message:

File could not be downloaded. Failed to open stream

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.

What should I do?

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.

eg:

 HTTP_PROXY="http://my-corp-proxy.mcdonalds" php composer.phar install

bonus points if you throw it into your bashrc if your on Linux/OS X or your environment settings for Windows.

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

@mlwacosmos on Win7 to add an environment variable you can follow this guide: http://www.itechtalk.com/thread3595.html you need to define HTTP_PROXY as variable name and `http://your.proxy.address.or.ip/` as value. Then you must restart CMD for composer to see the changes. – Seldaek Mar 07 '13 at 11:08

The right an easy way to run composer on windows under a proxy is opening the console (cmd), go to your project location and run this command:

C:\wamp\htdocs\myproject\> SET HTTP_PROXY=http://username:password@proxy.yourdomain.com:8080 && php composer.phar install

PD: You must changes parameters like: username, password, proxy.yourdomain.com and 8080 to yours

I hope this help to you

And DO NOT set https_proxy (just http_proxy)!

because https_proxy defaults to http_proxy if not set – DarkMukke Jan 10 '18 at 11:34
