Question

我很困惑。 rails test和rails console突然停止为我的项目工作，并且我找不到为引起问题而进行的任何最近更改。运行任何一个都会引发此错误：

    from -e:1:in `<main>'

Google搜索没有产生任何有用的建议。我尝试过检查较早的工作提交，并运行bundle install来使用其Gemfile.lock文件将gem降级，但是我仍然收到相同的错误消息。

如果我将其添加到其他Rails项目中，则rails test和rails console可以正常工作。

有人对从哪里开始寻找东西有任何想法吗？

非常感谢，
杰夫

Answer 1

Github上的某人建议我至少升级到Rack 2.0。那立即解决了我的问题。

Ruby on Rails测试和控制台均退出，并出现cache_control错误
