Trouble installing applications via pip on windows

Question

I get the following error when trying to install applications with pip.

    Collecting django
  Exception:

      'Not supported proxy scheme %s' % proxy.scheme
  AssertionError: Not supported proxy scheme abden003

I have tried running the following commands, but get the same error in both cases (I have tried using both python and python3):

pip install django

pip install django --proxy http://abden003:password@proxy.server.addr:port

pip3 install django

pip3 install django --proxy http://abden003:password@proxy.server.addr:port

The problem is not with my proxy server, since I tried it in a Linux vm and it works fine. It seems to be a problem with the windows version of pip.

I have tried the following but it did not fix the problem:

pip, proxy authentication and "Not supported proxy scheme"

Is it just django, did you try to pip install something else as well? — Zachary Weixelbaum, Jun 23 '15 at 19:25
Yes I have tried installing a few packages they all give the same error — abden003, Jun 23 '15 at 19:28

Did you try uninstalling and reinstalling pip, also are you sure that you are using the latest version of python (2.7.x or 3.x)? — Zachary Weixelbaum, Jun 23 '15 at 19:43

I have figured out how to fix the problem, it involved deleting a line of code. If you look at the last error it says the following:

    File "C:\Python34\lib\site-packages\pip\_vendor\requests\packages\urllib3\poolmanager.py", line 216, in __init__
      'Not supported proxy scheme %s' % proxy.scheme
  AssertionError: Not supported proxy scheme abden003

Go to:

 C:\Python34\lib\sitepackages\pip\_vendor\requests\packages\urllib3\poolmanager.py

in my case I went to C:\Python34\Lib.. instead of C:\Python34\lib

Open the poolmanager.py file, and delete line 215 which says the following:

    #  assert proxy.scheme in ("http", "https"), \
    #    'Not supported proxy scheme %s' % proxy.scheme

I don't if this line was accidentally left in, but removing fixed the problem and I was able to install packages via pip

you should run pip install django in command prompt instead of python shell.
