本项目使用vue/cli-4构建，在安装完less-loader后，npm run serve 时候报错，原因是webpack版本冲突

分析

在npm install 安装完依赖模块后，使用webpack -v查看webpack 版本（注意，如果已经全局安装webpack 该命令会显示全局安装的webapck版本，要查看局部安装的版本号可以使用 npx webpack -v 查看），此时我的局部的webpack版本是4.x.x。接着安装less-loader （npm install less less-loader -D）安装完成后，由于less-loader 版本是10.x.x 版本太高，其依赖的weback 版本为 5.x.x （在执行上面的命令安装less-loader 时，5.x.x的版本会被安装）此时node_modules中就有两个webpack版本，所以在执行 npm run serve 时出现冲突
