npm安装时出现的一些问题

问题1：

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! chromedriver@2.34.1 install: `node install.js`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the chromedriver@2.34.1 install script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\Y\AppData\Roaming\npm-cache\_logs\2018-01-27T10_39_44_245Z-debug.log

这是npm安装的时候，被墙了，可以用下面从国内镜像上来下载

npm install chromedriver –chromedriver_cdnurl=http://cdn.npm.taobao.org/dist/chromedriver

问题2：

这个是node-sass没有编译，可以用下面命令来重新编译一下

node rebuild node-sass
