Rails服务器不会运行mysql2宝石

**我知道这是一个流行的问题，但我似乎无法让它运行。我已经尝试了我读过的所有内容，并且问题依然存在。Rails服务器不会运行mysql2宝石

我正在使用RVM和1.9.2。我也使用MySQL 5.5，并且我已经重新安装了好几次。我的Ruby安装似乎可以很好地与SQLite协同工作，但它会扼杀MySQL。我已经检查过MySQL是否也在使用PHP，所以我知道这不是问题。 Rails似乎无法找到“libmysqlclient.18.dylib”文件。

这里是当我运行服务器会发生什么：**

如果您正在使用RVM机会是你不想sudo。

还请在代码块中设置您的代码的格式，以方便人们提供帮助。

阅读this post。它似乎是相同的。

我试过没有“sudo”，结果是一样的。不知道发生了什么事。 – MattK

对不起，这个混乱的问题，我会得到它重新格式化。我是StackOverFlow的新手。 – MattK

我通过你发送的链接阅读，并且这个命令'sudo install_name_tool -change libmysqlclient.18.dylib /usr/local/mysql/lib/libmysqlclient.18.dylib〜/ .rvm/gems/ruby-1.9.2-p290/gems/mysql2-0.2.11/lib/mysql2/mysql2.bundle'工作 – MattK
