I want to create my first project on ROR. I do everything according to the instructions, as described in these two links. Then in the console I enter the command:
C:\rails_projects\first_app>rails server The console displays the following message:

I have repeatedly seen similar topics on the Internet in people, but I really do not understand how to solve such problems of this kind. Tell me how this problem is solved in my situation and what should I do in the future if approximately the same problem will arise with other projects on ROR?
