Rails プロジェクトは完全に実行されていましたが、途中でいくつかの gem を再インストールし、rbenv と rvm を切り替える必要がありました。以前は rvm を実行していましたが、rbenv に切り替えたところ、大量の例外が発生し始め、rvm に戻そうとしましたが、それでも同じエラーが発生しました。

これは rvm/rbenv の問題ではなく、gem のインストール方法の変更であると考えています。

完全なスタック トレースは次のとおりです。

私の宝石のバージョン:

   gem 'rails', '3.0.20'
   gem 'mocha'

このことは過去 3 日間私を悩ませてきました。助けていただければ幸いです...

rails-3.0.9 から 3.0.20 にアップグレードするというコンテキストで、同様のスタックがありましたが、アプリのテスト中 ( rspec )

サーバーを実行するためにモカは必要ありません

Gemfile を確認する

mochaテストグループにその場所があります ( group :test do; gem 'mocha', '~> 0.10.0', require: false; end)

RVMセットアップが以前に機能していた場合は、次のことを行う必要があります。

  1. RVM環境のみで新しいコンソール/sshセッションを開きます
  2. rvm gemset remove my-gemset
  3. rvm gemset create my-gemset
  4. cd（.rvmrcファイルを自動的にロードするか、rvm gemsetがmy-gemsetを使用する必要があります）
  5. バンドルインストール

これにより、このアプリケーションの動作中のgemsetが再構築されます。
