IDB installs, but fails to run on OSX

[PhilKeeble]

Hi, I have been working with issues installing and finally got it working. It now runs gem install idb and succeeds. However, when I then run idb I get errors that I can't solve. I have looked through threads to see if someone was having similar issues. I have tried making it from source instead but same issue, I have tried altering the qtbinding version and manually building them from source (which was the only way to get it to install).

The error I get is:

/usr/local/rvm/gems/ruby-2.7.0/gems/plist4r-1.2.2/lib/plist4r/mixin/data_methods.rb:13: warning: constant ::Fixnum is deprecated

I was wondering if it was to do with the settings.yml file but couldn't see what it should be. It was left as default and I also tried to edit it to reflect the hostname of the iOS device etc, but neither worked.

If anyone could help me out with this it would be much appreciated, I am a Ruby noob.
