pip3 install peewee error m wrong cython version
That does indeed look like an invalid version number. Plus it's too old at any rate. yeah, I downloaded cython sources from repo and go through "python setup install" - all became OK 
Hi, when I install peewee from pip, have an issue: ValueError: invalid version number '0.20.1post0'
on vagrant/   Ubuntu Trusty 14.04.5 LTS, says: 
    **elif StrictVersion(cython_version) < StrictVersion(cython_min_version):**

look:
