stimulus-rails installation rails - undefined method Stimulus::Rails.application - ruby-on-rails

I have installed stimulus-rails gem on my rails 7 application. When I run the application, I get the following error.
The error is
Uncaught exception: undefined method `application' for Stimulus::Rails:Module
in lib/stimulus/engin.rb, Rails is somehow being interpreted as Stimulus::Rails instead of root class ::Rails.
Does anyone know how to handle this? Help would be greatly appreciated.
The following is the backtrace
=> Booting WEBrick
=> Rails 7.0.2.4 application starting in development http://0.0.0.0:3002
=> Run `bin/rails server --help` for more startup options

Maybe your version of ruby ​​doesn't match your version of rails, it gave me a similar error. You can see version compatibility here: https://www.fastruby.io/blog/ruby/rails/versions/compatibility-table.html . If you don't want to change the code, just try the ruby ​​version corresponding to your version of rails. In your case i would try using ruby ​​version 2.7

Ruby On Rails Server Issue (Ubuntu Bash on Windows 10)

In another thread I explained I am a newbie RoR. I had a problem with the puma 3.8.0 gem then I downgraded to fixed one issue. But, it created another problem:

I'm not too sure what I am looking at? Hoping someone can point me in the right direction.
According to https://github.com/rails/rails/issues/26054 you can create an app with:
rails new --skip-spring --skip-listen APP_NAME
As noted in the link above this should be fixed in Windows 10 Insider builds >= 14942.
I got rails server working using the command above to create my rails app.
My ruby version is 2.4.0p0, rails version is 5.1.0.beta1 and puma version 3.7.1.

Any rails server doesn't start

Getting the same error every time when trying to start ANY project on rails 4 or 5 using ruby 2.2.5 and 2.3.1 even on the fresh projects.
Tried to reinstall rbenv but didn't help. Anybody got a solution?

Seems like you have tabs in your YAML file instead of spaces.
Change them to spaces from your editor settings

So not realy sure what's going on but it started OK with 'sudo rails s'.

Updated Rails to 4.2.1 and now it won't run

I have no idea what's going on. I updated my rail to version 4.2.1 and now I can't generate a server. I run
$rails s
like normal and it starts up fine but then immediately exits. I've pasted the message below. Any ideas would be greatly appreciated
=> Booting WEBrick
=> Rails 4.2.1 application starting in development on http://localhost:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server
Exiting
