rails服务器不会运行WEBrick

Question

我是一个新手，尝试按照Rails教程并成功运行http://railsinstaller.org/

中的安装例程

我还安装了mysql

我使用了命令＆gt; rails new simple_cms -d mysql

这似乎成功运行

我跑的时候 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

我遇到了同样的问题。因为在Mac OS X上，mysql通常安装在/usr/local/mysql中，您需要手动设置libmysqlclient中/usr/lib的路径。

在终端中运行：

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