Installing ruby gems from behind proxy firewall

Generic Instructions

If you are trying to install/update a ruby gem from behind a proxy you should follow these instructions.

  1. Create a system environment variable named HTTP_PROXY containing the IP address of your proxy and the port number. The value should be something like:
    http://192.168.10.10:8080

    You should be able to find this information in your browser settings.

  2. Close and relaunch any command windows. Ruby gems should now work.

Specific Instructions for Windows users

On Windows you can view/edit/create system environment variables by right clicking My Computer and selecting Properties. Select the Advanced tab and then click Environment Variables. Click New under System Variables and enter HTTP_PROXY as the name and your IP address and port as the value.
