我是 Rails 新手，在运行 rake 测试时收到以下消息。这是一个基于 Rails 社区引擎的应用程序。
我尝试创建一个测试应用程序只是为了确保我的 gems 等没有问题，并且我能够在该应用程序中成功运行 rake 测试。
如果有人能阐明问题所在，那就太好了......

最佳答案
错误永远不会是单独解决的足够信息。然而，如此简单的事情，您是否已经运行了 sudo rake gems:install？
我也在下面看到这一行
app/controllers/users_controller.rb line 17
我们还需要查看您的 Controller 。
如果你只使用 rake 会发生什么？
