can't pip install some software on s4

[johnjung]

If I try to install software on s4 with pip, I get error messages like the following:

pip install docopt

Collecting docopt (from -r requirements.txt (line 1))
Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ConnectTimeoutError(<pip._vendor.urllib3.connection.VerifiedHTTPSConnection object at 0x807cdb2e8>, 'Connection to pypi.org timed out. (connect timeout=15)')': /simple/docopt/
...

Running pip install with the verbose flag shows me that I'm not able to download the following file: https://pypi.org/simple/docopt/

If I do "curl https://pypi.org/simple/docopt/" from s4, the command just hangs. But that same command from my local machine works fine. Can you tell what's going on here?

s4 is on a private IP, so you'll need a proxy server. For an example, look at the gitconfig file on that server:

root@s4:~ # more /usr/local/etc/gitconfig 
[http]
        proxy = http://torus.lib.uchicago.edu:8080

Thanks very much, Fred. That solves the problem.
