rails服务器不会运行WEBrick

我是一个新手，试图遵循Rails教程并成功运行安装例程来自http://railsinstaller.org/

我也安装了mysql

我使用了命令> rails new simple_cms -d mysql

这似乎成功运行

当我运行rails服务器

这是下面的输出 – 似乎没有在端口3000上启动WEBrick

非常感谢

我有同样的问题。 因为在Mac OS X上，mysql通常安装在/usr/local/mysql ，所以需要手动设置/usr/lib libmysqlclient的路径。

在终端中运行：

 sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib
