I then check for http env variables:

env | grep -i http
http_proxy=

So I have an empty http_proxy variable. Should it fail with that?

After doing

unset http_proxy

And running

pip install --use-mirrors virtualenv

I can install it no problem.

Should it behave this way?

Thanks!

i was having the same problem while trying to install virtualenv. i do have a proxy server and other things like curl, port, etc. are able to use my environment variables. but pip doesn’t seem to recognize them so i have to provide my proxy to it each time i use it.

things worked out for me when i used my proxy settings with the command

sudo pip --proxy=http://username:password@proxyURL:portNumber install virtualenv

give it a try if you are actually behind a proxy server. if you are not, then i’m afraid i can’t diagnose your problem. though i’d guess that you have some kind of network connectivity issue.
