通过 Lynda 对 Ruby on Rails 的培训，我通过rails s 命令启动了 WEBrick 服务器。我和视频在同一目录/Users/myuser/Sites/simple_cms

我收到以下错误：

/usr/local/lib/ruby/gems/1.8/gems/mysql2-0.3.2/lib/mysql2/mysql2.bundle: dlopen(/usr/local/lib/ruby/gems/1.8/gems/mysql2 -0.3.2/lib/mysql2/mysql2.bundle, 9): 库未加载: libmysqlclient.18.dylib (LoadError)

我按照指示@Unable to start rails server
仍然收到错误。我也按照指示@rails server fails to start with mysql2 using rvm & ruby 1.9.2-p0 on OSX 10.6.5
任何帮助，将不胜感激。

【问题讨论】：

输入rails server是否有效？
我仍然遇到同样的错误。

【解决方案1】：

好的，经过进一步研究，我找到了自己的答案

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

这是为我做的。以防其他人无法通过原始解决方案解决此问题。
