actually, I did meet this problem before, but finally , I try to install re3 which is the new version of re2. It worked. And everything is going fine now.
after you install the re3, the process of importing this library is the same

like:

> import re2

The re2 , what we're going to install , is the version 0.2.22 and the re3 is the version 0.2.23.

Hopefully, this will help you!

Not on a mac - osx 10.13.5

$ pip3 install re3
Collecting re3
Could not find a version that satisfies the requirement re3 (from versions: )
No matching distribution found for re3

Works with python2, not with python3.
