Question

I just installed Python on Windows 7 as described on http://docs.pylonsproject.org/projects/pyramid/en/1.4-branch/narr/install.html. Im at step 3 and get the following error when I run the python ez_setup.py command. I go the ez_setup.py from this URL http://peak.telecommunity.com/dist/ez_setup.py

c:\Python27>python ez_setup.py
Downloading http://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11-p

I found issue to the problem. It was due to a network proxy which can be fixed with the following command. `set http_proxy=user:password@proxyaddress:port`. I hope this helps someone — Andre Dixon, Sep 18 '14 at 18:45

The answer is in the comment above.

When you are behind a proxy, there is an Windows environment variable which is used to store the proxy setting.

That variable is http_proxy and for secure https_proxy.

The format of setting this variable is below

set http_proxy=user:password@proxyaddress:port
set https_proxy=user:password@proxyaddress:port

If there is no password, then do the following

set http_proxy=user@proxyaddress:port

So an example would be

set http_proxy=jbrown:jbpass@192.168.0.252:8080
