Courses Plus Student 5,417 PointsDepending on your Ruby version you might be able to just run Bundle install to solve this. Also I would make sure to check if your database is running in the back.

5,375 Pointstype rails --version to see what version of rails you have active. Once you see what version you have active. Type gem list to see if you have more then one rails installed on your computer. If you do then you can uninstall the oldest rails you have by typing gem uninstall rails "VERSION OF YOUR CHOOSE"
You also may need to install or update the gem byebug.
