想在本机上装Bootstrap的源码，需要安装Grunt。
按照官网的表述，在执行npm install时，出现了很多报错。
希望有人指点一下是什么原因？还要装其他的环境吗？
以下为命令行：

F:\Office software2\bootstrap-3.2.0>npm install
npm WARN deprecated [email protected] : Package was renamed to 'grunt-jscs
'
npm WARN package.json [email protected] No repository field.
\

[email protected] install F:\Office software2\bootstrap-3.2.0\node_modules\grun
t-contrib-qunit\node_modules\grunt-lib-phantomjs\node_modules\phantomjs
node install.js
