TypeError: this.getOptions is not a function

原因： sass-loader安装的版本过高
解决方案：
1.npm uninstall sass-loader
2.npm install sass-loader@6.0.0

ValidationError: Invalid options object. Sass Loader has been initialized using an options object that does not match the API schema. - options has an unknown property ‘additionalData’. These properties are valid: object { implementation?, sassOptions?, prependData?, sourceMap?, webpackImporter? }
