mysql錯誤幫助...運行耙db：設置RAILS_ENV =「生產」

我努力嘗試讓MySQL啓動並運行我的第一個rails應用程序。運行耙分貝時，我不斷收到以下錯誤：安裝RAILS_ENV =「生產」：mysql錯誤幫助...運行耙db：設置RAILS_ENV =「生產」

rake aborted! 
dlopen(/Library/Ruby/Gems/1.8/gems/mysql2-0.3.2/lib/mysql2/mysql2.bundle, 9):  Library not loaded: libmysqlclient.18.dyl Referenced from: /Library/Ruby/Gems/1.8/gems/mysql2-0.3.2/lib/mysql2/mysql2.bundle

我的計算機運行雪豹時，MySQL 5.5，寶石mysql2，軌道3

任何幫助是巨大的。非常感謝。

您是否曾嘗試在命令的開頭添加'bundle exec'，以便在捆綁的gem環境中運行它？ – Ant 2011-06-05 14:26:52

這是否有所作爲：'rake db：setup RAILS_ENV = production' – apneadiving 2011-06-05 14:55:50

否則，顯示您的'database.yml'文件 – apneadiving 2011-06-05 14:56:52

看起來你需要安裝mysql2庫：

sudo apt-get install libmysqlclient-dev libmysqlclient16

另外，我建議你如果您使用的是Rails 3.0.x，請在您的Gemfile中使用gem 'mysql2','0.2.7'。進行此更改後，請不要忘記運行bundle install。
