報(bào)錯(cuò)情況如下：

解決方法：
主要是windows平臺(tái)缺少編譯環(huán)境，
1、先運(yùn)行： npm install -g node-gyp
2、然后運(yùn)行：運(yùn)行 npm install --global --production windows-build-tools
可以自動(dòng)安裝跨平臺(tái)的編譯器
npm uninstall node-sass
npm i node-sass --sass_binary_site=https://npm.taobao.org/mirrors/node-sass/
接著就可以
npm install
npm run dev
