完成了 Ruby on Rails 的 Lynda 培训，并通过rails s命令启动了 WEBrick 服务器。我与视频在同一目录中 /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)

我按照说明@Unable to start rails server
仍然收到错误消息。我还按照指示@ rails server failed 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。

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

这为我做到了。以防其他人无法通过原始解决方案解决这个问题。
