vue2老项目中node-sass更换dart-sass

更换原因：node-sass经常会出现node版本问题，就很麻烦

卸载项目中的node-sass sass-loader

npm uninstall sass-loader sass 

安装dart-sas sass-loader 推荐安装sass@1.26.2 sass-loader@7.3.1

npm install sass-loader@7.3.1 sass@1.26.2

从新配置vue.config.js

// vue.config.js
module.exports = {css: {loaderOptions: {sass: {implementation: require('sass'), // This line must in sass option},},}
}

然后需要全局替换一下/deep/，全局搜索 /deep/ , 将项目里的 /deep/ 替换为 ::v-deep

如果使用了stylelint，需要修改配置规则

// stylelint.config.jsmodule.exports = {...rules: {'selector-pseudo-element-no-unknown': [true,{ignorePseudoElements: ['v-deep'],},],},...};
