How to install the ruby bundler behind a proxy with sudo.
To use ruby bundler behind a proxy, define the proxy host in env variables http_proxy and https_proxy.
For instance
export http_proxy=http://10.0.2.2:3128
export https_proxy=https://10.0.2.2:3128
However if you need to sudo, because you have no write permission on the ruby gems folder, sudo does not preserve the http_proxy env variable. Therefore add following line in /etc/sudoers
Defaults env_keep = "http_proxy ftp_proxy"
before this line:
Defaults env_reset
After this you can install the bundler gem.
