Uninstallation fails with WindowsError: [Error 206] The filename or extension is too long

[BoboTiG]

• Pip version: 9.0.1
• Python version: 2.7.14
• Operating system: Windows 7 (32 and 64 bits)

Description:

pip install --upgrade MODULE fails to uninstall the old version if its full path is too long.
To reduce the path length, I set the envar TMPDIR to the shortest possible, eg C:\temp by still.

What I've run:

2 demonstrations, the 1st when ugrading pip from 9.0.1 to 9.0.3:

Possible solution:

I know Windows has a "long path prefix" \?\\ but I do not know if it is a viable option and if eventual Windows API implied there will still work with such a patch.

Perhaps there already is a workaround I did miss?

Duplicate of #3055?

[BoboTiG]

Ah yes, it seems the same. I did not find it because I was looking for the specific WindowsError. Should I close this one?

[pradyunsg]

Sure. Feel free to. :)
