yarn start失败

yarn install的时候报错
error E:\web\demo\ECharts\7-react-admin-ts-master\node_modules\node-sass: Command failed.
Exit code: 1
Command: node scripts/build.js
Arguments:
Directory: E:\web\demo\ECharts\7-react-admin-ts-master\node_modules\node-sass
Output:

"name": "node-sass",
"version": "4.14.1",

然后我卸载node-sass，并尝试用cnpm安装
使用cnpm install node-sass@4.14.1这个命令；
淘宝源
cnpm install node-sass@4.14.1
npm ERR! code 1
npm ERR! path E:\web\demo\ECharts\react-echarts-ts\node_modules\node-sass
npm ERR! command failed
还是会报错

更新完nodes-sass会包这个错。
应该是版本不对。
