1. 安装依赖

npm install style-resources-loader 
npm install vue-cli-plugin-style-resources-loader 

我用的版本
“style-resources-loader”: “^1.4.1”,
“vue-cli-plugin-style-resources-loader”: “~0.1.5”

2. 配置vue.config.js

const path = require("path");pluginOptions: {"style-resources-loader": {preProcessor: "less",patterns: [path.resolve(__dirname, "./src/assets/vantless.less")]}},

./src/assets/vantless.less 指向 全局less文件
