Answer 1

您使用哪个版本的 rubocop-rails？

在我的情况下，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

Answer 2

好像你有类似的东西： require: rubocop-rails 在您的 rubocop 配置文件链中的某个位置。但是您的 gemfile 中没有包含 gem 'rubocop-rails'。

请在您的 gemfile 中包含 gem 'rubocop-rails'，这应该可以解决。
