问题与OS Rails的宝石mysql2 X 10.7使用Ruby 1.9.2和Rails 3.1

OS版本：的Mac OS X 10.7.1狮子
红宝石版本：ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin11.1.0]
红宝石地点：/usr/local/rvm/bin/ruby
Rails的版本：Rails 3.1.0
Rails的位置：/usr/local/rvm/gems/ruby-1.9.2-p290/bin/rails问题与OS Rails的宝石mysql2 X 10.7使用Ruby 1.9.2和Rails 3.1

现在，我安装了mysql2的宝石，当我运行gem list它显示在列表中：mysql2 (0.3.7)

到目前为止好，是吧？好的，所以这里就是棘手的地方。无论我做什么，我都无法启动服务器。在终端，我cd到我的Rails应用程序的目录并运行rails s。然而，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，这不是什么应该发生。问题是我不明白为什么不。我遇到的解决方案都没有工作。

这实际上是我第一次尝试让Ruby/RoR在我的电脑上工作。我正在使用Lynda.com的一个教程，毫不奇怪，这不会发生在做视频的人。

我试过寻找，正如我所说，似乎没有任何帮助。想法？

史蒂夫用我错过的答案指出了另一个问题。该解决方案如下：须藤LN -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib 我的猜测是，因为我安装了多用户，而比单用户其他解决方案没有正确排队。但是，这是。 – dougoftheabaci

install_name_tool -change libmysqlclient.18.dylib /usr/local/mysql/lib/libmysqlclient.18.dylib ~/.rvm/gems/[email protected][gemset name]/gems/mysql2-0.3.7/lib/mysql2/mysql2.bundle

[宝石名称] =你正在使用的宝石的名称 - 如果你没有设置一个，那么你应该将其设置为是获得RVM

希望的要点之一这有助于
