運行ruby應用程序的問題

Question

我在Windows上使用RubyMine，所以我可以在rails應用程序上運行給定的ruby。當我點擊運行，我得到以下錯誤：

我並不真正熟悉的紅寶石，但它說的東西，對此，我已經安裝並添加到PATH變量「MySQL的」。 有什麼幫助嗎？ Thx

Answer 1

這可能是版本問題。當我用新的mysql gem使用舊的mysql版本時，我確實遇到了同樣的問題。

請您找到您的mysql服務器所需的正確gem。

Answer 2

您安裝的MySQL gem期望特定版本的MySQL libmysql.dll在您的系統中可用（當您在gem install mysql中顯示控制檯中正確的圖例時）。

mysql_api.so無法加載，從而導致您看到的錯誤。

我已經介紹了一種替代方法來安裝和編譯MySQL組件，與您安裝的MySQL版本無關。

希望有所幫助。
