ruby-rubocop 无法加载此类文件 — rubocop/rspec/focused

Question

我已经为 VSCode 安装了 ruby-rubocop，并且 gem 安装了 rubocop，但是每次我保存文件时，都会抛出这个错误：

请帮忙，我一直在努力完成这项工作，并在互联网上寻找解决方案。 但还没有运气。

Answer 1

该 cop 是rubocop-rspec插件的一部分，因此您可能还必须运行gem install rubocop-rspec 。

Answer 2

发现并解决了问题。

事实证明，罪魁祸首是：

1. rubocop -v 0.85.0
2. rubocop-rspec

由于我们的组织使用的是旧版本，因此修复只是降级。 所以现在我安装了：

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