webpack 5.88.2 compiled with 1 error in 2761 ms

出现这个错误的原因是没有正确安装node-sass，因此重新安装即可

bash 复制代码

npm i [email protected]

如果npm安装不成功或者安装错误，改cnpm安装

bash 复制代码

cnpm i [email protected]

安装完成，重新npm run dev运行项目就好了

bash 复制代码

 *  正在执行任务: npm run serve 


> [email protected] serve E:\AA-MengZhuKeJiWork\projects\mengzhu-mini
> npm run dev:h5


> [email protected] dev:h5 E:\AA-MengZhuKeJiWork\projects\mengzhu-mini
