安装时报警告
less-loader@10.2.0 requires a peer of webpack@^5.0.0 but none is installed. You must install peer dependencies yourself.
项目中使用less样式时报错
ERROR Failed to compile with 1 error error in ./src/App.vue?vue&type=style&index=0&lang=less& Syntax Error: TypeError: this.getOptions is not a function
因为vue脚手架使用webpack4版本，less-loader8以上版本需要webpack5 安装less-loader7版本即可
npm i less-loader@7 less
