Wrong path being used for idb_companion

[kmarple1]

Description

I have installed idb_companion per the documentation. which idb_companion returns "/opt/homebrew/bin/idb_companion". However, I keep seeing this error in Flipper (full log entry below): "FileNotFoundError: [Errno 2] No such file or directory: '/usr/local/bin/idb_companion'".

[heath-clink]

See https://github.com/facebook/idb/pull/851

However, that ~may~ will not get merged because I'm not willing to try to get my employer to sign the CLA.

Perhaps someone who does have a CLA might be willing to duplicate the change in the PR into their own PR.

[heath-clink]

this appears to work as a workaround:

sudo ln -s /opt/homebrew/bin/idb_companion /usr/local/bin

[Mansouri147]

For me I literally changed the path in the file throwing the error, this is the file path ~/Library/Python/3.9/lib/python/site-packages/idb/cli/main.py line number 313 which is await root_command.run(args) just added one line before it args.companion_path="/opt/homebrew/bin/idb_companion"

thanks, it's worked for me

Thankyou so much. I've been debugging this issue for about 4 hours now I can now sleep.

sudo ln -s /opt/homebrew/bin/idb_companion /usr/local/bin

Thanks! It works for me.
