I have tried running ./env/bin/pip install werkzeug==0.16.1 inside my frappe-bench directory but still nothing.

Any help would be much appreciated.

@deschant, are you working on a MacOS system?

It seems to be picking up your user Python environment instead of the bench’s.

I’m not sure of a proper fix, but as a workaround (only recommended if you don’t have any other apps using Python locally), you might want to install / re-install werkzeug in your local Python environment.

Yes @RohanB I am using MacOS.
I have a fresh python3.8 installation. Might there be some common configuration that I could be missing which would cause this ?

I’m not sure actually. I’ve seen this happen on another colleague’s system, but he wasn’t using Python for any other application, so the workaround was enough for work :sweat_smile:

Try this:

./env/bin/pip3 install werkzeug==0.16.1
(Installs in bench python3 virtual environment)

Or just pip3 install werkzeug==0.16.1
(Installs in python3 environment)
