项目需要使用scss 的时候，编译报错    Invalid options object. Sass Loader has been initialized using an options object that does not match the API schema.

具体报错内容如下

Failed to compile with 1 error

Syntax Error: ValidationError: Invalid options object. Sass Loader has been initialized using an options object that does not match the API schema.

报错原因是 sass-loader 版本搞了，查看自己 package.json ,需要降低版本,换成 V7版本就可以了

 

 

 解决方法：

npm install --save sass-loader@7.1.0
// 或者 ,测试通过两个

npm install --save sass-loader@7.0.1
