ruby-rubocop 無法加載此類文件 — rubocop/rspec/focused

Question

我已經為 VSCode 安裝了 ruby-rubocop，並且 gem 安裝了 rubocop，但是每次我保存文件時，都會拋出這個錯誤：

    cannot load such file -- rubocop/rspec/focused

請幫忙，我一直在努力完成這項工作，並在互聯網上尋找解決方案。 但還沒有運氣。

Answer 1

該 cop 是rubocop-rspec插件的一部分，因此您可能還必須運行gem install rubocop-rspec 。

Answer 2

發現並解決了問題。

事實證明，罪魁禍首是：

1. rubocop -v 0.85.0
2. rubocop-rspec

由於我們的組織使用的是舊版本，因此修復只是降級。 所以現在我安裝了：

1. rubocop -v 0.75.1
2. rubocop-rspec-focused
