Question

我是一名前端开发人员，希望在Rails工程方面有所了解。我过去曾参与过几个rails项目，我的机器配置为可以处理这些项目。但是，我正在尝试设置我自己的rails应用程序，到目前为止，我已经在正确的目录中创建了新项目，但是当我尝试运行我的服务器“$ rails server”时，我的localhost：3000端口没有显示任何内容，我收到以下错误：

任何帮助都将不胜感激。

Answer 1

你正在使用Rails 2，它的命令是完全不同的。 rails server只会在Rails 3和4中启动服务器，在Rails 2中，这将创建一个名为“server”的新应用程序;你正在寻找rails script/server。

你应该真正开始使用Rails 4 - 不再支持Rails 2。

Answer 2

试试rails script/server。但是你应该真正考虑将rails升级到更新的版本。

不知道为什么我不能运行我的rails服务器
