Pypy (2) breaks on importing parse

[Bachmann1234]

When installing dateparser the most recent version of the regex library is installed which seems to break in pypy (works in pypy3 in my experiments)

When I uninstall it and install the version in your requirements.txt the import seems to work fine. Here is my session

Im not sure if yall want to pin the version in setup.py or if there is an issue that I should file over at the regex project.

We are removing support for Python 2 and Pypy, so I will close this issue. Thank you all for raising this. In any case, we are discussing if we will add support for Pypy3 in this issue: https://github.com/scrapinghub/dateparser/issues/745. If you are interested, let me know your insights.
