Uncaught exception: You have already activated ruby-debug-ide 0.4.23, but your Gemfile requires ruby-debug-ide 0.4.22. Using bundle exec may solve this.
There was two version of ruby-debug-ide 0.4.23 and ruby-debug-ide 0.4.22. we must have to uninstall one of them. just follow the processes: 1. gem list 2. gem uninstall ruby-debug-ide 3. select 1 or 2 (which one you want to uninstall) 4. bundle install
It will work in_sha_allah.
