No module named 'SimpleWebSocketServer'

[GlauberF]

I installed SimpleWebSocketServe, through the pip as the repository shows (https://github.com/dpallot/simple-websocket-server), but when I run npm start, I get the error

Try running pip install -r requirements.txt

I already did this procedure, but I tried again

Which output do you get from python --version and pip --version? It's possible that your default Python installation has version 2.7, but pip actually modifies the packages for Python 3.

Maybe python2.7 -m pip install -r requirements.txt helps in this case, but I have not tested that myself yet.

It's quite unfortunate that the code in this repository still depends on Python 2.7, but for now we'll have to deal with it.

Ahh, there you have it! Your system is configured to only use Python 3.

Try executing python2.7 -m pip install -r requirements.txt then (if you haven't done so already), then change the two occurrences of python ./backend/whatsapp_web_backend.py in the root package.json to python2.7 ./backend/whatsapp_web_backend.py.

Any ideas for my case?

pip 20.3.1 from /home/user/.local/lib/python3.6/site-packages/pip (python 3.6)

I am writing after trying to resolve this myself in vain. Any ideas?
