@Meggle1
Could you try running this?

/root/.local/pipx/venvs/glances/bin/python -m glances

If this works, then what you were executing earlier was system-wide installation of glances available through your OS package manager or sorts.

[saoirse-source]

It does, what does this mean exactly?

Thanks for the response

[ItsR3B00T]

So is there a fix for this? Keep getting the same error when trying to use web server mode

[albertogasparin]

I’m also facing this issue with the version installed via brew (osx Sonoma). Tried the command above and it works, but when I add -w to trigger the web interface the command still fails due to FastAPI

[RobK88]

@albertogasparin -- Once my PR is merged, please try Macports. I got glances -w to work using the latest versions of glances, py-fastapi, py-annotated_doc and py-uvicorn. See macports/macports-ports#30558
