For some reason, PyJTW doesn't seem to work on my virtualenv on Ubuntu 16.04, but it worked fine on my local Windows machine (inside a venv too). I'm clueless, I've tried different versions, copied the exact same versions as I had on my Windows machine, and yet I still couldn't get this to work.

Installed packages:

ModuleNotFoundError: No module named 'jwt.algorithms'

I'm running Python 3.7.7.

I had the same issue. The error seems to be a conflict between the pyjwt and jwt modules (as mentioned by @vimalloc above). What worked for me was to run the following command (NOTE: I am using Python 3.6.10).

pip3 install -U pyjwt

You don't have to register with the 'RSAAlgorithm'. You have install the 'cryptography' too:

PyJWT==2.3.0
cryptography==36.0.1

Then you can just use the "RS256" algorithm without registration:

import jwt
jwt.encode(payload, private_key, algorithm="RS256")
user_82443380

You shouldn’t have both the jwt and PyJWT packages installed, they have some namespace collisions. Try removing the jwt package and see if it works.

It turned out to be an issue with my Python environment. I recreated it a few times, and eventually, it would work. I suspect that there are multiple jwt's that were somehow installed.
