在Windows上的virtualenv中使用pip和easy_install

Question

I was trying to install a few packages in a virtual environment using pip. I was getting the error:

Downloading/unpacking pymongo
  Cannot fetch index base URL https://pypi.python.org/simple/
  Could not find any downloads that satisfy the requirement pymongo
No distributions at all found for pymongo

I found that some say a workaround is downgrading your pip. I downloaded and installed pip 1.2.1 Now I get the error:

(env1)PS C:\dev\virtualenvs> pip install bottle
Downloading/unpacking bottle
  Cannot fetch index base URL http://pypi.python.org/simple/
  Could not find any downloads that satisfy the requirement bottle
No distributions at all found for bottle

The log says:

urlopen error [Errno 10013] An attempt was made to access a socket in a way forbidden by its access permissions>

How do I correctly use virtualenvs on windows?

EDIT: I am able to use pip when not in my virtualenv.

Answer 1

In this case the operating system should not matter. Also this should not be a question about virtualenv (as suggested in your title). pip just cannot access the remote end that it would like to access. Does it take some time for the error message to appear (is this a timeout issue)? If yes, then this is a networking issue, maybe triggered by a firewall. You should check this first.
