Fontcustom doesn't work after upgrading to Catalina

[axelferdinand]

When running "fontcustom compile" I get this error:

-bash: /usr/local/bin/fontcustom: /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby: bad interpreter: No such file or directory

Had the same issue, after the catalina upgrade, Ruby version is not the same, and somewhere a configuration file is not updated accordingly. You have to delete / reinstall all the dependencies from scratch and update your ruby version using rvm, after this it should work.

@splio-rtheys what exactly should be deleted and reinstalled?

I am getting this issue when running compile:
