bundle install hangs inexplicably

Question

I am on RHEL 6, and have built Ruby from source and installed into /usr/local .

The server I am on does not have outside internet access, EXCEPT to access Rubygems.org. That is the only outside connection it is permitted to make. This is a corporate security restriction and there is nothing I can do, so please don't say 'use rvm'. I would if I could...

I need to run bundle install as a certain user, ciwasadm . But when I do, the terminal just hangs. When I run bundle install or gem install whatever as my username, wannia1 , I am able to connect to Rubygems.org and get wahtever I need.

For some reason, the hanging only occurs when I am sudo'ed into ciwasadm . The Ruby installation for both users is working and I can run ruby files in the command line. I just don't understand why bundler is any different.

Running gem env for ciwasadm returns:

I'll post my solution here with the hopes that it helps someone else in the future.

Bundler was hanging because it could not reach the rubygems.org server. This is because a proxy was required, but had not been set.

I was able to run export http_proxy=<insert proxy info here> in my bash shell, and then was able to dial out.
