pip install traceback error while installing packa

Question

I'm having issues to install python packages using 'pip', i have no problems until a couple of days ago, but now suddenly I have the error below every time i want to install something. I'm using Python 2.7 on windows, and I already reinstall 'pip' by still the same.

Traceback (most recent call last):   
   File "C:\Python27\Scripts\pip-script.py", line 9, in <module>
   load_entry_point('pip==1.5.6', 'console_scripts', 'pip')()

  File "build\bdist.win32\egg\pkg_resources.py", line 339, in load_entry_point
    ns.clear()

  File "build\bdist.win32\egg\pkg_resources.py", line 2470, in load_entry_point
    else:

  File "build\bdist.win32\egg\pkg_resources.py", line 2184, in load
    raise ValueError

    from requests.compat import IncompleteRead

ImportError: cannot import name IncompleteRead

Answer 1

According to this bug, you likely have a bad version of requests installed. It sounds like you need to remove requests completely and any reference to it and reinstall it using something other than pip. Otherwise pip may reinstall the old version using its cache.
