rails创建项目报"please update your path to include build tools...."

刚装好rails,想新建一个工程测试rails是否安装正确。执行完rails new demo之后提示“please update your path to include build tools....”
解决方法:
1、登录http://rubyinstaller.org/downloads/下载devkit。注意选择正确的版本。
2、下载完了之后解压到任意一个目录。我解压到了D:\ruby
3、在dos下进入到你解压的目录(我的是D:\ruby),依次执行ruby dk.rb ruby dk.rb init 和 ruby dk.rb install
5、在执行ruby dk.rb install会提示你修改config.yml文件。
6.、编辑config.yml文件,把你安装ruby目录的绝对路径写入到这个文件中。(比如我的ruby是安装在D:\ruby\Ruby22-x64这个目录中)
7、保存。重新执行ruby dk.rb install
8、重新安装rails。执行gem install rails
