Module build failed: TypeError: this.getOptions is not a function
at Object.lessLoader (E:\a-website-render\node_modules\less-loader\dist\index.js:19:24)
安装less-loader并且在页面写上lang="less"后，运行就报这个错
这是因为less-loader版本过高导致的，卸载后重新装即可
npm install less-loader@5.0.0 --save-dev
Module build failed: TypeError: this.getOptions is not a function at Object.lessLoader
