How to solve a RubyMine "'ruby-debug-ide' isn't installed" error
Complementing Ahsan Ellahi
In your terminal you're probably not running the same ruby version as inside Ruby Mine. You can check this
In Ruby Mine
Preferences --> Laguanges and Frameworks --> Ruby SDK and GemsIn Terminal
$ ruby-vIf you're not running the same version, try to set RubyMine to use the same Ruby version that you're running in your terminal. This should solve the problem. Than, if you really want to use another RubyVersion, you will need to go to your terminal, change the Ruby version and manually install both gems
Here's the actual command that worked for me:
gem install ruby-debug-ide --pre
I have faced this issue when debugging in a docker-compose environment. I suspect that RubyMine does not refresh the list of available gem after the SDK is added.
So if you add the SDK then add ruby-debug-ide to Gemfile you will get the error.
Instead, (re)create the SDK after adding ruby-debug-ide.
