ruby-on-rails - Ruby on Rails Localhost 路由问题

Question

我正在关注 this tutorial .一切顺利，直到我尝试创建一个 Controller 并在我的浏览器中查看它。

服务器正在运行，它显示默认页面正常 (http://127.0.0.1:3000)。

我在命令行中运行了 ruby script\generate controller MyTest，它生成了正确的文件夹和文件。

问题是，当我访问 http://127.0.0.1:3000/My_Test/ 时，它说:

We're sorry, but something went wrong.

We've been notified about this issue and we'll take a look at it shortly.

这一定是我忽略了什么地方。感谢您的帮助!

ruby 1.8.6

rails 2.3.4

刚刚检查了我的开发日志。这是它说的:

我不知道这是什么意思，但我注意到一件事是它说 sqlite3 - 我没有使用它(我正在使用 MySql)。这是问题所在吗？

这是一个非常古老的教程，从那以后很多事情都发生了变化。

可以查看this相反。
