ruby on rails - How to use bundler behind a proxy?

Question

I get the following output from the sudo bundle install command:

Fetching source index for `http://rubygems.org/`  
Could not reach rubygems repository `http://rubygems.org/`  
Could not find gem 'rspec-rails (>= 2.0.0.beta.22, runtime)' in any of the gem sources.

I have $http_proxy set correctly and I've added gem: --http-proxy=my proxy to ~/.gemrc. These settings are what allow my gem commands to work, and I was hoping they would translate to bundler, but no such luck.

Thinking sudo might not inherit my all of my environment, I also added those settings to my root user, but nada.

At this point bundler is preventing me from deploying my application, and I can find very few others running into this. If no one has an answer I will be forced to rip bundler out of my Rails app (which I wouldn't mind doing...)

OSX & Linux

export http_proxy=http://user:password@host:port
export HTTP_PROXY=$http_proxy

If it's using HTTPS, set it as well

export https_proxy=http://user:password@host:port
export HTTPS_PROXY=$https_proxy

If you use sudo, by default sudo does not preserves http proxy variable. Use -E flag to preserve it

$ sudo -E bundle install

to make sudo preserves environment variables by default:

Windows

As pointed by answers below, you can use SET instead

SET HTTP_PROXY=http://user:password@host:port
SET HTTPS_PROXY=%HTTP_PROXY%
