WEBrick Rails服務器無法正常工作

Question

我的操作系統是Windows 10

今天，我已經安裝了Ruby（紅寶石2.2.3p173（2015-08-18修訂版51636）[x64-mingw32]）和rails gem（rails 4.2.4）

我正在按照一系列有關Rails的教程視頻中介紹的過程進行操作。 我安裝了以下版本的myqsl 2（並且如果是惡意安裝則重新安裝）mysql2-0.4.1-x64-mingw32

這個問題與一個名為simple_cms的應用程序有關，該應用程序按照教程中的說明以以下方式創建

rails new simple_cms -d mysql

我有：

• 運行捆綁安裝幾次
• 二手寶石清理
• 運行bundle exec rails服務器
• 嘗試耙db：create並捆綁執行rake：db，按照此處的建議創建每個方法
• 重新安裝mysql2幾次

但是在輸入

rails server

在我的項目simple_cms的根目錄中。 WEBrick甚至無法啟動

作為此處和此處其他類似問題的示例，兩個查詢者都收到以下內容

=> Booting WEBrick
=> Rails 3.2.13 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

等.... WEBrick失敗之前。 但是，由於沒有提到與WEBrick有關的任何內容，因此我沒有走得太遠。 以下是在輸入rails server命令后收到的錯誤消息：

我現在要一遍又一遍地嘗試相同的事情，並且正如愛因斯坦正確地指出，精神錯亂的定義是一遍又一遍地做同一件事並且期望得到不同的結果時，可以做些什么來糾正這種情況。

這是版本railties和rails寶石之間的問題。 是的，答案很復雜。 為了將來的發展，請嘗試為您的項目使用某些版本控制系統（ Rbenv ）
