I had initially discovered that I had issues with my Python environment and it was a hot mess. I have since installed pyenv and am working with Python 3.8 I am not able to get watchdog to install. I have removed and reinstalled Xcode and command line tools.

Can someone suggest what's going wrong so that I can hopefully get watchdog installed right?

Can someone tell me anything about this? I'd love to be able to use watcher...

@Geordon I'm also facing this issue. Any solutions here?

If anyone stumbles onto this issue now. The solution for me was to uninstall the homebrew version of gcc with brew uninstall gcc. Then you can do a which gcc and gcc -v to make sure you're using Apple clang.

My error message was different however: no option -Wunused-command-line-argument

In my case I had installed a really outdated LLVM version with Homebrew:

/usr/local/bin/clang -> /usr/local/Cellar/llvm@4/4.0.1/bin/clang

I removed it using:
brew uninstall llvm@4

Now it picks /usr/bin/clang:

clang --version
Apple clang version 12.0.0 (clang-1200.0.32.2)

Note that the apple v12 has to do with XCode, and not the upstream LLVM version,
which is version 10 as of the time of writing this comment.

PS: this whole compiler toolchains, libraries and headers, that have to go through xcode / xcode command line tools,
is a bit of a mess! :)

This should be mostly resolved now that watchdog==1.0.2 provides built distributions, but this will still be a problem for new macOS ARM platforms until #740 is resolved.
