想在本机上装Bootstrap的源码，需要安装Grunt。
为此，依次安装了nodejs（v4.2.2 LTS）, git。
然后，执行npm install -g grunt-cli，貌似也成功了。
（执行：grunt -version，能看到 grunt-cli v0.1.13）
然后在下载了Bootstrap源码，解压，进入其目录
执行：npm install时，报错：

可以我已经安装了git，而且也加入到了PATH里面。
命令行敲：git --version
可以显示：git version 1.9.5.msysgit.0
1，grunt-cli安上了 grunt还没安上，执行npm install grunt@0.4.3
2，不用手动下载bootstrap，项目目录下执行npm install bootstrap就好
