I’m using Mac OS Big Sur with Xcode 13.2.1. I would like to run rdebug-ide in my Rails 6 (Ruby 3.0.2) app but not quite sure what version of debase I need, which is a requirement to install rdebug-ide as I understand it. When I try to install the debase gem, I get the errors …
$ gem install debase
Building native extensions. This could take a while...
ERROR: Error installing debase:
