在 mac os 上使用 MySQL 啟動 rails 服務器時出現錯誤

Question

我一直在修補這個好幾天，我仍然得到同樣的錯誤。 對於初學者，我已經能夠以 sqlite 作為數據庫啟動一個新的 rails 應用程序，但我們正在處理的應用程序使用 Mysql。 所以當我 go 到應用程序目錄並輸入“rails server”時，它給了我以下信息：

 /Users/gojinjedi/.rvm/gems/ruby-1.9.2-p180@rails3/gems/mysql2-0.2.7/lib/mysql2.rb:8:in `require': dlopen(/Users/gojinjedi/.rvm/gems/ruby-1.9.2-p180@rails3/gems/mysql2-0.2.7/lib/mysql2/mysql2.bundle, 9): Library not loaded: libmysqlclient.18.dylib (LoadError)

所以（我認為）MySQL 開發頭沒有安裝，我到處搜索如何安裝它們並嘗試了大多數安裝命令行但沒有成功。 我嘗試過的命令示例：

gem install mysql2

sudo env ARCHFLAGS="-arch i386" gem install mysql --   --with-mysql-dir=/usr/local/mysql --with-mysql-lib=/usr/local/mysql/lib   --with-mysql-include=/usr/local/mysql/include

我在應用程序目錄中執行了捆綁安裝、捆綁更新和捆綁命令……我的選項用完了……你能幫幫我嗎？

我在 mac osx 10.7

你嘗試過這樣的事情嗎，我也是一個 Mac OS X（獅子），我對 mysql gem 沒有任何問題。 或者你可以在這里找到你想要的

或者您可以簡單地將 ruby-mysql gem 用於開發環境
