你安裝了Ruby [DevKit]（http://jekyll-windows.juthilo.com/1-ruby-and-devkit/）嗎？ – MarsAtomic

是的，我安裝它 –

什麼版本的鐵軌？ – pixelearth

代碼頁720是通過MS-DOS使用阿拉伯字符。

建議您將終端代碼頁切換爲Ruby能夠理解的內容，例如拉丁字母的窗口1252字符編碼。

您的問題可以通過這個命令來解決

chcp 1252

一個更好的方法是不斷地迫使終端通過使用批處理一樣this使用權代碼頁，即。

此外，對於Ruby on Rails開發人員，最好使用帶有rvm或rbenv的Linux。
