rails s error os x 10.8.4 rvm

Question

我只是在安装 ruby​​ / rails / gems 等。我安装了 rvm 并且收到了许多与这篇文章类似的错误，不确定是否相关。我相信我通过安装 ruby​​ 文档解决了这些问题。

安装完所有东西后，我可以使用以下命令创建我的项目，看起来很成功

rails new simple_cms -d mysql

然后我运行以下命令并收到以下错误，

jg$ rails s

我遇到过类似的问题。添加类似于以下内容的符号链接对我有用：

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

请试一试。
