Answer 1

1.npm update

2.npm install gulp-sass --save-dev in your root folder

2. 如果报gulp[12560]: c:wssrc ode_contextify.cc:635: Assertion `args[1]->IsString()' failed.

安装node.js的原生javascript模块 natives

解决：

npm install natives

---------------gulp-------------

//全局gulp

npm install gulp -g

//项目里通过package.json安装指定模块

npm install
