rubocop 無法加載此類文件 -- rubocop-rails

我安裝了 gem rubocop 。 當我運行時：命令rubocop終端響應：

請幫幫我 ！！！

Answer 1

好像你有這樣的東西： require: rubocop-rails在你的 rubocop 配置文件鏈中的某個地方。 但是您還沒有在您的 gemfile 中包含gem 'rubocop-rails' 。

請在您的 gemfile 中包含 gem 'rubocop-rails'，這應該得到解決。

Answer 2

您使用哪個版本的 rubocop-rails？

就我而言，2.1.0 版本很好。

$ bundle update rubocop-rails
...
Installing rubocop-rails 2.1.0 (was 1.5.0)
Bundle updated!

$ bundle console
Frame number: 0/18
[1] pry(main)> require 'rubocop-rails'
=> true
