我很難找到解決這個問題的方法。我發現了錯誤:如何解決請安裝mysql適配器:`gem install activerecord-mysql-adapter`(不需要這樣的文件加載-java)
rake db:migrate
(in /home/EXPRESS.LOCAL/shevchenko/web/tmp)
DEPRECATION WARNING: Rake tasks in vendor/plugins/paperclip/tasks and vendor/plugins/restful-authentication/tasks are deprecated. Use lib/tasks instead. (called from /home/EXPRESS.LOCAL/shevchenko/.rvm/gems/ruby-1.8.7-p371/gems/rails-2.3.8/lib/tasks/rails.rb:10)
rake aborted!
Please install the mysql2 adapter: `gem install activerecord-mysql2-adapter` (no such file to load -- java)
我試圖卸載耙0.9.2.2安裝0.8.7,然後更改適配器:MySQL來適配器:mysql2。
這裏是我的寶石:

@ cybern0va但您的數據庫已遷移或不? – Thanh
沒有。但我更新mysql2到最新版本和我的數據庫遷移,但我收到錯誤:警告:此版本的mysql2(0.3.11)不附帶ActiveRecord適配器捆綁了,因爲它現在是Rails 3.1的一部分 警告:如果您打算在Rails中使用它,請使用0.2.x版本<= 3.0.x PS對不起4我的英語:) – cybern0va
