I get a slightly different (but I think related) error when trying to run this on macOS.

Uninstalling and reinstalling requirements with pip did not change anything.

Does running pip install flask_jwt fix the error?

[brandon-haugen]

@adam-cowley Unfortunately, no it does not.

[adam-cowley]

Are you using Python version 3.10? I've had another report today about it not working, the project was written with 3.9

[brandon-haugen]

3.10 on an M1 MacBook... maybe the M1 is the problem.

[alielbashir]

I'm getting the same error running Python 3.10.4 on Ubuntu 22.04

[alielbashir]

Downgrading to Python 3.9.12 fixes this for me

[maovidal]

It seems it won't work on 3.10, as Python 3.9 warns:

python3.9/site-packages/jwt/api_jwt.py:5: DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated since Python 3.3, and in 3.10 it will stop working

[adam-cowley]

I'm working on a permanent fix for this as I upgrade the Neo4j Driver to 5.0. Stay tuned 👀
