stimulus-rails installation rails - undefined method Stimulus::Rails.application #103

Closed jaehocho closed 2 years ago

jaehocho commented 2 years ago

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

Issue was due to stimulusjs-rails gem. I removed the gem and it worked. Stimulusjs-rails defined Stimulus::Rails
