私はRails 5.0.1を使用しています。私はRailsサーバとは独立したバックグラウンドプロセスを実行したい。私は作業プラグインが私を助けてくれると思った。https://github.com/ascarter/workling。しかし、私のGemfile"初期化されていない定数ActiveSupport :: CoreExtensions"は、ワークリング・プラグインをロードしようとしています
gem 'workling'
にこの宝石を追加し、私のサーバーを再起動すると、私はこのエラーを取得
Gem Load Error is: uninitialized constant ActiveSupport::CoreExtensions
