I had a feeling boto3 or its dependencies were causing this issue, and seemed to be right.
I reinstalled Pythonista3 and imported flask without issues. Then I installed ptinstaller and stash and could still import flask (as expected). Then I installed boto3 (and deps) via pip/stash.
Restarted pythonista and tried to import flask. Then I received this error again!
Now I just installed flask via pip and this seems to work. I can now import flask and boto3.
Hi, I am trying to install psycopg2 but get the following error.

Thank you for your reply.
I see in stash that flask was not installed using pip... I could install it with pip but I'm afraid for weird side effects..
I suspect it must be something I installed which are causing this issues. I did install a few scripts using ptinstaller. I uninstalled them but still same error. I did install some packages using pip, like boto3. I'll check what others I installed using pip.

When I import flask I get the error below. I had this before and resolved it by reinstalling pythonista. After reinstalling I can import flask without issues (I am not really using it yet in my scripts but plan to do so soon), but later it fails again.
Any idea what could be wrong?
