node-sass 安装失败 Failed at the node-sass@4.9.2 postinstall script的解决

控制台运行npm install时报错，报错信息如下：


npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! node-sass@4.9.2 postinstall: `node scripts/build.js`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the node-sass@4.9.2 postinstall script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.



解决方法：

1、卸载node-sass

运行：npm uninstall node-sass


2、重新安装指定的node-sass版本(安装失败的版本)

运行：npm install node-sass@4.9.3


3、如果还是安装不成功的话，或者安装太慢连接不上，使用一下淘宝镜像后重复1,2步骤，成功后再npm install

使用淘宝镜像运行：npm config set registry https://registry.npm.taobao.org
