[BUG] prospector2 won't install on Windows apparently since using forward slash instead of os.path.join

[Poikilos]

The prospector2 package doesn't install on Windows (Python 2.7).

• Additionally, where is prospector2? The pypi page links to here. I can't tell if this is a fork of anything because it doesn't say so in the GitHub interface, but the pypi page says prospector2 is a Python 2 fork of prospector.

To Reproduce Steps to reproduce the behavior:

1. Open a Windows Command Prompt
2. py -2 -m pip install prospector2
3. See error

Expected behavior

• Should install prospector2
• Should use os.path.join

Screenshots

>py -2 -m pip install prospector2

This error seems to go away after I fix the long path test (See #3).
