rails generate が全然動かない！時に試すこと

railsでコントローラーを作ろうと思ったら...

Rails 6.0.3.1 にて
いいね機能を実装すべく、likes_controller.rbを作りたくて以下のコマンドを実行しました。

$ rails g controller likes

...うんともすんとも言わない

止めよう（^Cぽち）

うわ
どうやらspringというのが怪しい

解決方法

springを止めちゃいます。

$ spring stop
Spring stopped.

止まります。
rails g を再度実行！

$ rails g controller likes
Running via Spring preloader in process 23035
      create  app/controllers/likes_controller.rb
      invoke  erb
      create    app/views/likes
      invoke  test_unit
      create    test/controllers/likes_controller_test.rb
      invoke  helper
      create    app/helpers/likes_helper.rb
      invoke    test_unit
      invoke  assets
      invoke    scss
      create      app/assets/stylesheets/likes.scss

できた

ちなみに

さっき止めたspringですが、ステータスを確認するとしっかり動いていると思います。

$ spring status
Spring is running:
