Question

操作系统版本： Mac OS X 10.7.1 Lion
Ruby版本： ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin11.1.0]
Ruby位置： /usr/local/rvm/bin/ruby
Rails版本： Rails 3.1.0
Rails位置： /usr/local/rvm/gems/ruby-1.9.2-p290/bin/rails

现在，我安装了mysql2 gem，当我运行gem list时，它会在列表中显示为：mysql2 (0.3.7)

到目前为止这么好，对吗？好的，所以这里变得棘手。无论我做什么，我都无法启动服务器。在终端我cd到我的rails应用程序目录并运行rails s。但是，而不是开始我得到这个：

/usr/local/rvm/gems/ruby-1.9.2-p290/gems/mysql2-0.3.7/lib/mysql2.rb:9:in `require': dlopen(/usr/local/rvm/gems/ruby-1.9.2-p290/gems/mysql2-0.3.7/lib/mysql2/mysql2.bundle, 9): Library not loaded: libmysqlclient.18.dylib (LoadError)

    from script/rails:6:in `require'
    from script/rails:6:in `<main>'

显然，这不应该发生什么。问题是我无法弄清楚为什么不。我遇到的解决方案都没有奏效。

这实际上是我第一次尝试在我的计算机上运行Ruby / RoR。我正在关注Lynda.com的教程，不出所料，这不会发生在制作视频的人身上。

我试过搜索，正如我所说，似乎没有任何帮助。想法？
