Ruby on Rails的 - Couln't找到mysql2.so

Question

我一直在Ruby on Rails的2個月以來走，現在我想改變數據庫系統，所以我安裝了該命令的寶石mysql2：

寶石安裝mysql2 --platform = ruby​​ - '--with-mysql-lib =「C：\ mysql-connector \ lib」--with-mysql-include =「C：\ mysql-connector \ include」--with- mysql-dir =「C：\ mysql-connector」'

它的工作原理！

，但問題是，當我想運行Rails服務器再次我得到這個錯誤

c:\zreactor\demo>rails server

我搜索源，它看起來一切就OK了，我不知道爲什麼我得到這個錯誤。

我正在W8上使用ruby 2.0和rails 4.0.2。

謝謝你的幫助， 謝謝！

最有可能你需要重新libmysql.lib如下所述：

...mysql2/mysql2.so: [BUG] Segmentation fault ruby 2.0.0p247
