Glances cannot start in web server mode in MacOS
Closed this issue · 0 comments

After installing on my macbook pro using homebrew, I get the following error when starting the web server:
% glances -w
FastAPI import error: No module named 'fastapi'
Glances cannot start in web server mode.
I've also installed FastAPI via homebrew, but it has no effect.
Steps to reproduce the behavior:
- Install glances via homebrew:
brew install glances - Run glances in web server mode:
glances -w - See above error
Expected behavior
Glances to run out of the box in webserver mode, and to find the fastapi dependency correctly.
Environment (please complete the following information)
- Operating System:
MacOS Sonoma 14.7 - Glances & psutil versions:
Glances version: 4.2.1, Glances API version: 4, PsUtil version: 6.1.0 - How do you install Glances:
brew install glances - Glances test:
% glances --issue

There is no configuration file. The log file only contains these lines repeated for each time I tried to launch with -w:
