debase failing to install on Mac

[ghost]

My environment:

MacOS Monterey Version 12.3.1
Ruby 3.1.0

I did:

xcode-select --install

Then I installed ruby-debug-ide:

gem install ruby-debug-id

Install went fine.

Then I tried to install debase:

gem install debase

And I got a bunch of errors. Here's the output of my mkmf.log:

I am on MacOS Monterey Version 12.6, ruby 2.6.6p146

Facing the same issue when trying to install debase.

I then open xcode (dint open after updating macOS to Montery) and let it update, then run sudo xcodebuild -license.

After that error becomes ERROR: While executing gem ... (Errno::EACCES) Permission denied @ rb_sysopen -

I then install the gem with sudo, sudo gem install debase -v 0.2.4.1 and that works for me.

Hope this helps.
