railsでモデルが作成できず困っております。

Question

railsでTaskモデルを作りたく、以下のコマンドを実行しました。

bin/rails g model Task name:string description:text

すると、マイグレーションファイルやモデルが作成されることがなく以下のようなエラーメッセージが出てきました。

ネットで色々調べたところ「spring」が原因であると考え、コマンド$ spring stopを実行しSpring stoppedと表示された上で再度

bin/rails g

を実行しましたが同じエラーが出てきてしまい依然モデルは作成できないままです。
対処法をどなたかご回答頂けると幸いです。

config/application.rb の 20行目でエラーが起きているみたいなのでそのあたりのコードを載せると回答がつきやすいと思います。

config/application.rbを確認したところ、問題点が見つかり解決致しました。ご指摘ありがとうございました！

Answer 1

/Users/takehaya/taskleaf/config/application.rb:20:in `<top (required)>': undefined local variable or method `config' for main:Object (NameError)

このメッセージのとおり、まずはconfig/application.rbの20行目とその前後の文脈を確認してみましょう。

config/application.rb を確認し修正したところ、無事モデル作成ができました。ありがとうございました。
