What Worked for Me

As per: https://stackoverflow.com/a/39214538/2805700

This is fixed as of Werkzeug 0.11.15. Make sure you have installed the latest version of Werkzeug. pip install -U werkzeug.

So I ran pip install -U werkzeug

Updated requirements.txt should to Werkzeug>=0.14.10

u should install a new version of werkzeug
Pycharm->defaultsetting->+ at right top->then search werkzeug
or pip install -U werkzeug
