我已经使用 rvm implode 重新安装了 RVM、Ruby 和所有 gem。当我运行 rubocop 时，我收到一条错误，指出它正在使用 2.5(我没有明确安装，但似乎随 RVM 的 Ruby 2.5.1 一起提供)
请注意我用 * * 突出显示的行 - 这可能是问题所在？

最佳答案
对 Ruby 2.5 的支持已添加到 version 0.52.0 中的 Rubocop| 。但您使用的是 0.49.1。
您需要将 Rubocop 至少更新到版本 0.52.0，甚至更好地更新到最新版本(截至今天为 0.63.1)。
根据您的设置，您只需运行 bundle update rubocop 或者您可能需要先在 Gemfile 中指定所需的版本。
