Fontcustom not working after Catalina OS upgrade

[paufar]

I keep getting this issue when I try to run the compile command. I have tried uninstalling and reinstalling everything and am running out of options to try. How can this be solved? What could be causing the issue?

Got it working on a macOS Catalina clean install! The missing part was:
brew tap bramstein/webfonttools
brew install sfnt2woff

(Note on the debug, somewhat at the end, it says something about a missing "sfnt2woff")

So in a full install instructions should be:

brew tap bramstein/webfonttools
brew install woff2 sfnt2woff eot-utils
brew cask install fontforge
sudo gem install fontcustom

and edit your PATH to include both Ruby and FontForge paths:
/usr/local/lib/ruby/gems/2.6.0/bin
/Applications/FontForge.app/Contents/Resources/opt/local/bin

in my .zshrc I have (may need cleaning):
export PATH=$HOME/bin:/usr/local/lib/ruby/gems/2.6.0/bin:/Applications/FontForge.app/Contents/Resources/opt/local/bin:/usr/local/bin:/usr/local/sbin:/Users/MYUSER/.composer/vendor/bin:/usr/local/opt/ruby/bin:/$PATH

@andrefelipe thanks! This solved our issue!
FontCustom is working again on Catalina :)

I have a similar problem and adopted @andrefelipe's solution.
But I can not find this path:
/usr/local/lib/ruby/gems/2.6.0/bin
Here is my log:
