Installing Ruby on Rails

对于新手推荐使用Railsinstaller来安装Ruby on Rails，刚开始减少在安装阶段过多的纠缠，快速进入框架学习阶段。

1.下载Railsinstaller

site:http://railsinstaller.org/

对新手来说，Railsinstaller非常方便，里边包含了所有ROR需要的软件，可谓一站式安装。

2.安装Railsinstaller

唯一一点要注意的是，安装路径不要有空格

3.安装完之后，输入github的用户名和邮箱

4.重开一个命令行，查看各个组件是否安装成功

C:\Documents and Settings\XPMUser>ruby -v
ruby 1.9.3p392 (2013-02-22) [i386-mingw32]

C:\Documents and Settings\XPMUser>rails -v
Rails 3.2.13

C:\Documents and Settings\XPMUser>gem -v
1.8.24

5.(optional)更新rails

C:\Documents and Settings\XPMUser>gem update rails
Updating installed gems
Nothing to update

到这里安装基本就算完成了，接下来测试下安装成果，创建一个项目看看运行情况,创建一个最简单的待办事务

Use `bundle show [gemname]` to see where a bundled gem is installed.
Post-install message from rdoc:
Depending on your version of ruby, you may need to install ruby rdoc/ri data:

<= 1.8.6 : unsupported
= 1.8.7 : gem install rdoc-data; rdoc-data --install
= 1.9.1 : gem install rdoc-data; rdoc-data --install
>= 1.9.2 : nothing to do! Yay!
