不確定為什么我不能運行Rails服務器

Question

我是一位前端開發人員，希望對Rails工程有所了解。 過去，我從事過一些Rails項目，而我的機器被配置為可以在那些項目上工作。 但是，我正在嘗試建立自己的rails應用程序，到目前為止，我已經在正確的目錄中創建了新項目，但是當我嘗試運行服務器“ $ rails server”時，我的localhost：3000端口卻沒有顯示任何內容，並且出現以下錯誤：

任何幫助，將不勝感激。

Answer 1

您使用的是Rails 2，其命令完全不同。 rails server將僅在Rails 3和4中啟動服務器，在Rails 2中將創建一個名為“服務器”的新應用程序； 您正在尋找rails script/server 。

您應該真正開始使用Rails 4-不再支持Rails 2。

Answer 2

嘗試使用rails script/server 。 但是，您應該真正考慮將Rails升級到新版本。
