Answer 1

我們需要從頭這裏開始：

1. 使用Windows安裝程序從http://rubyinstaller.org/downloads/
2. 安裝Ruby安裝捆綁： gem install bundler
3. 對於Windows的MySQL，我認爲你需要的的devkit。從http://rubyinstaller.org/downloads/
4. 獲取與您的操作系統相匹配的電源請確保您的電腦上安裝了mysql。
5. 確保mysql2 gem安裝正確。如果gem install mysql2未正確安裝，則可能需要如下內容：gem install mysql2 -- --with-mysql-dir="C:\mysql\bin";改變c:\mysql\bin的位置，可以在步驟安裝mysql 4
6. 安裝導軌：gem install rails
7. 轉到目錄C：\網站\ simple_cms和類型：bundle install
8. 現在試圖啓動您的服務器：rails s

Windows上的Rails開發有了很大的改進，但如果你真的想保持最新並避免將來出現一些奇怪的問題（尤其是在支持gem的時候），我建議你使用Ubuntu。如果你沒有另一臺電腦或者不想進行雙啓動，你可以免費安裝VirtualBox（https://www.virtualbox.org/wiki/Downloads），並運行Ubuntu。
