Additional context
Any information/guidance here would be appreciated! I realize you support 3.7, though this seems relevant.

It is probably a Python incompatibility related dependency version error. Although we have a lock file, we might still need to pin certain dependencies. Which version of Python did you use?

[ryanmrestivo]

Hey, thanks for your response -- Python 3.11.4

[orhun]

Uh, that's a bit problematic. We simply stopped maintaining this project in 3.7 so these kinds of errors are expected. (definitely fixable tho!)

Is there any chance that you can downgrade to 3.7 and try again to see if the error persists? I recommend using a pyenv or rye (experimental) for doing so.

[ryanmrestivo]

Completely removed python, installed 3.7, new errors haha

[orhun]

Oh damn, maybe check out https://stackoverflow.com/questions/71850969/importerror-cannot-import-name-run-with-reloader-from-werkzeug-serving

I'm afraid this issue is about to turn into a wormhole 🪱

[ryanmrestivo]

You were right, it is a wormhole!

werkzeug doesn't like markupsafe 2.1.3... it looks like markupsafe removed soft_unicode which is causing this error. (pallets/markupsafe#304)
I attempted to downgrade to 2.0.1, but werkzeug isn't compatible. Any recommendations on downgrading werkzeug? Or am I off-track?

I appreciate your help!

[orhun]

I think the most durable solution would be to support the latest version of all the libraries that are used in the project which means a quite a bit of work. I would say let's go back to the latest Python and focus on somehow solving that error instead of getting stuck in the past.

[ryanmrestivo]

Ok - Fixed! Steps taken to remediate so far on python 3.11

File "C:\Python311\Lib\site-packages\prompt_toolkit\styles\from_dict.py"

line 9, in
changed "from collections import Mapping" to "from collections.abc import Mapping"

Then upgraded flask_socketio
pip install --upgrade flask_socketio

Thanks!

[orhun]

Glad that this is resolved!
