Ruby on rails 运行rails服务器时出现问题

我刚刚在MacOSX10.7.4上使用rails安装程序安装了rails env

我使用“railsnew”命令创建一个项目

当我尝试运行“rails服务器”命令时，我收到以下消息：

当我运行$ruby-v和$gem-v时，我分别得到“ruby 1.9.3p194”和“1.8.24”。我错过了什么？如何使此服务器运行？

看起来您正试图在Rails 2.3中使用Rails 3.x命令。在3.0之前，您必须使用服务器脚本

从应用程序目录中运行：

./script/server

将rails作为gem安装，

gem安装rails

。当您使用rvm时，此处显示的文件夹路径显示rails 2.3.4，同时您尝试运行

rails服务器

。检查/更改gem文件中的rails版本，然后进行捆绑安装

看，还有。所有3种解决方案都是

gem安装rails

。您是否使用自制软件安装rails？请参阅和。这三种解决方案都是

gem安装rails

。您是使用自制软件安装rails的吗？非常感谢！继承了一个Rails2.x项目，并且为了解决这个问题而发疯。非常感谢！继承了一个Rails2.x项目，并疯狂地试图解决这个问题。
