vue 项目使用 scss 升级 node v12 后报错 TypeError: this.getResolve is not a function

项目之前基于 node v8 创建，后来升级 node v12 后 node-sass 报错，执行 npm rebuild 同样报错。后来重新安装 node-sass 和 sass-loader 后出现如下错误。

error  in ./src/scss/app.scss

Module build failed (from ./node_modules/sass-loader/dist/cjs.js):
TypeError: this.getResolve is not a function
    at Object.loader (G:\code\nideshop-admin-vue\node_modules\sass-loader\dist\index.js:52:26)

 @ ./src/scss/app.scss 4:14-220 14:3-18:5 15:22-228
 @ ./src/main.js
 @ multi (webpack)-dev-server/client?http://192.168.1.123:9093/sockjs-node (webpack)/hot/dev-server.js ./src/main.js

使用 npm install --save sass-loader 安装的版本为 8.0 , 由于 8.0 版本移除了相关函数，导致出现 this.getResolve is not a function 错误。

sass-loader 8.0 版本更新信息如下：

move all sass (includePaths, importer, functions) options to the sassOptions option. The functions option can't be used as Function, you should use sassOption as Function to achieve this.

解决方法：降低 sass-loader 版本

npm uninstall sass-loader
npm install [email protected] --save-dev
