npm install安装包常见错误

1.报错：npm ERR! Unexpected end of JSON input while parsing near '...stylish":"1.0.0","gul'

解决方法：npm cache clean --force

2.警告：npm WARN invalid config registry=""

npm WARN invalid config Must be a full url with 'http://'

解决方法：npm config set registry http://registry.npm.taobao.org 

npm config set registry可以设置国内镜像
