Answer 1

我们需要从头这里开始：

1. 使用Windows安装程序从http://rubyinstaller.org/downloads/
2. 安装Ruby安装捆绑： gem install bundler
3. 对于Windows的MySQL，我认为你需要的的devkit。从http://rubyinstaller.org/downloads/
4. 获取与您的操作系统相匹配的电源请确保您的电脑上安装了mysql。
5. 确保mysql2 gem安装正确。如果gem install mysql2未正确安装，则可能需要如下内容：gem install mysql2 -- --with-mysql-dir="C:\mysql\bin";改变c:\mysql\bin的位置，可以在步骤安装mysql 4
6. 安装导轨：gem install rails
7. 转到目录C：\网站\ simple_cms和类型：bundle install
8. 现在试图启动您的服务器：rails s

Windows上的Rails开发有了很大的改进，但如果你真的想保持最新并避免将来出现一些奇怪的问题（尤其是在支持gem的时候），我建议你使用Ubuntu。如果你没有另一台电脑或者不想进行双启动，你可以免费安装VirtualBox（https://www.virtualbox.org/wiki/Downloads），并运行Ubuntu。
