Description of issue

Glances 4.2.1 on MacOS runs in standalone mode, but not in webserver mode.

% glances -w
FastAPI import error: No module named 'fastapi'
Glances cannot start in web server mode.

I've installed fastapi as well using brew, but it still doesn't see the dependency. I'm not sure whether this brew fastapi package is even relevant:

% fastapi --version
FastAPI CLI version: 0.0.5

Glances log doesn't really show any additional information:

Seems like a lot of stuff. Not sure if homebrew has a way of simplifying things, but I tried (I think) just fastapi and uvicorn and it didn't seem to work.

Does homebrew have a packaging concept like pip, to break things down into default glances vs glances[web] vs glances[all]?
