            Bug ID: 46108
           Summary: Wine creates env var with empty string for name and it
                    breaks python-pip
           Product: Wine
           Version: 3.17
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs at winehq.org
          Reporter: stu.axon at gmail.com
      Distribution: ---

When I try and install things using pip (from python 2.7, since python 3.5
install doesn't work right not).

it fails, with 

*** ValueError: illegal environment variable name

If I open the python interpreter I can see there is an env var with the name of
an empty string:

>>> import os
>>> os.environ['']
'Z:=Z:\\home\\stu\\Downloads'


I had a look at this outside of wine and the env var doesn't show up when
running the same python.

I edited pythons pip code to remove the env var:
~/.wine/drive_c/Python27/Lib/site-packages/pip/_internal/utils/misc.py

I changed these lines:

    env = os.environ.copy()
    if extra_environ:
        env.update(extra_environ)

To:

    env = os.environ.copy()
    if extra_environ:
        env.update(extra_environ)
    env.pop('')


And then pip succeeds
