vue/cli创建的typescript项目，引入less一直报错Syntax Error: TypeError: this.getOptions is not a function

错误提示如下

Syntax Error: TypeError: this.getOptions is not a function
 @ ./node_modules/vue-style-loader??ref--10-oneOf-1-0!./node_modules/@vue/cli-service/node_modules/css-

原因

是less-loader安装的版本太高，卸载重新安装7.0版本即可
