公司新发的项目，运行出来报这个错误，这是什么原因，是不是依赖的版本问题

./node_modules/normalize.css/normalize.css (./node_modules/_css-loader@6.5.1@css-loader/dist/cjs.js??ref--6-oneOf-3-1!./node_modules/postcss-loader/src??ref--6-oneOf-3-2!./node_modules/normalize.css/normalize.css)
Module build failed (from ./node_modules/_css-loader@6.5.1@css-loader/dist/cjs.js):
TypeError: this.getOptions is not a function
at Object.loader (D:\Work\work\Examination\exam-vue\node_modules_css-loader@6.5.1@css-loader\dist\index.js:31:27)

1.npm uninstall css-loader
2.npm install css-loader@5.0.0

执行这个 。应该是 css-loader版本太高了

缺少文件或代码有问题

npm rebuild node-sass
