Answer 1

我解決this..i只需走進Gemfile中，改變了mysql2提及MySQL和東西工作得很好...

Answer 2

您提供的輸出中的最後一行清楚地表明您錯過了什麼。它提到沒有安裝gem mysql2，並且您應該運行bundle install來安裝它們。

你沒有提到你如何獲得該版本的Ruby，但我會假設你安裝了Rubyinstaller包。

現在，mysql2 gem目前缺少Windows的二進制文件（這是我正在處理的東西）。

我有兩個建議：無論您使用的sqlite3（它應該制定出與RubyInstaller盒子或專門RailsInstaller包

或者你下到RubyInstaller wiki發佈有關安裝的那些類似的說明進行安裝和編譯mysql2寶石。和編譯MySQL適配器。

希望這一切都有助於或有意義。
