how can i find what version of rails my app is running on?

I am trying to run an old rails app, but I am receiving this error after calling $ rails server:

uninitialized constant AppGenerator::Config
Did you mean?  RbConfig

I am brand new to Rails, and I really don't know what this means/where to start. The app is supposedly built on 2.3.8. My computer says I have 2.4.1 and 2.3.18 installed.

I would like to know if I should install 2.3.8, or if I should upgrade to the latest version? Also I don't understand the error that is coming up, where should I look in the app to fix this - or is this a Rails problem?

Verify the version your project is built type bundle show inside it. It's gonna show all the gems and your respective versions.

And to check the rails version just type rails -v in your terminal.

You can check the rails version on Gemfile.

Try the command rake about to see the application environment.

I would suggest to have your environment setup same on the Gemfile, your application might have compatibility issues if you use a lower version.

The gemfile in the app folder should tell you what version of rails it is.

You can use bundle update to update the version or if you have a newer version and want an older version, do gem uninstall rails and then gem install rails -v "version number" for example, gem install rails -v 2.3.8.
