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[email protected] [email protected]

npm install [email protected] [email protected]

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.js
	module.exports = {
	  ...
	  rules: {
	    'selector-pseudo-element-no-unknown': [
	      true,
	      {
	        ignorePseudoElements: ['v-deep'],
	      },
	    ],
	  },
	  ...
	};
