Rails服務器不會運行mysql2寶石

**我知道這是一個流行的問題，但我似乎無法讓它運行。我已經嘗試了我讀過的所有內容，並且問題依然存在。Rails服務器不會運行mysql2寶石

我正在使用RVM和1.9.2。我也使用MySQL 5.5，並且我已經重新安裝了好幾次。我的Ruby安裝似乎可以很好地與SQLite協同工作，但它會扼殺MySQL。我已經檢查過MySQL是否也在使用PHP，所以我知道這不是問題。 Rails似乎無法找到「libmysqlclient.18.dylib」文件。

這裏是當我運行服務器會發生什麼：**

如果您正在使用RVM機會是你不想sudo。

還請在代碼塊中設置您的代碼的格式，以方便人們提供幫助。

閱讀this post。它似乎是相同的。

我試過沒有「sudo」，結果是一樣的。不知道發生了什麼事。 – MattK

對不起，這個混亂的問題，我會得到它重新格式化。我是StackOverFlow的新手。 – MattK

我通過你發送的鏈接閱讀，並且這個命令'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
