Based on your path (/home/...) it looks like you are running Linux. Is that correct? FSEvents is a macOS only thing I believe.

watchdog/src/watchdog/observers/fsevents.py

Line 21 in 75a3289

:platforms: macOS

What is the bigger picture here that lead you to run into this error?

Regardless, it could certainly be useful to provide a better message here to help out developers.

Yup it's on Linux - actually it's on codespace. It is used on other library (pyedifice) so I installed watchdog, and ran into this error.

Current version of pyedifice doesn't handle this exception well (It actually checks exception, but expects wrong exception.) so I ran into the problem.

Guess it's more like problem of said library.

At present, I think it is likely that your issue will be addressed by a change in the other library. But, let's leave this issue open as there is room for improvement around the handling of this in watchdog itself.
