node-sass 安裝失敗 Failed at the node-sass@4.9.2 postinstall script的解決

控制台運行npm install時報錯，報錯信息如下：


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.



解決方法：

1、卸載node-sass

運行：npm uninstall node-sass


2、重新安裝指定的node-sass版本(安裝失敗的版本)

運行：npm install node-sass@4.9.3


3、如果還是安裝不成功的話，或者安裝太慢連接不上，使用一下淘寶鏡像后重復1,2步驟，成功后再npm install

使用淘寶鏡像運行：npm config set registry https://registry.npm.taobao.org
