pip install failed. Could be fixed by changes in versioneer.py

First of all: Thank you for this awesome tool! :)

Description

I had a problem installing prolint2. This error occurred both with pypi and with the local installation:

Installing build dependencies ... done
  Getting requirements to build wheel ... error
  error: subprocess-exited-with-error

  × Getting requirements to build wheel did not run successfully.

  note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed to build 'file:///home/<myusername>/tools/prolint2' when getting requirements to build wheel

Todos

After changing the parts included in this PR, installation was successful.

Questions

Is this error caused by version conflicts? Could this PR also prevent installation problems on other systems then mine too? If not, I understand if the PR is rejected ;)
