运行 Angular 项目会出现 Node-sass 错误

Question

我正在本地环境中运行一个 Angular 项目，其版本如下。

npm version : 6.9.0
Angular CLI: 7.3.9
Node: 10.16.0
OS: win32 x64

我无法运行项目并收到以下错误：

    ERROR in ./src/assets/styles/style.scss (./node_modules/@angular-devkit/build-angular/src/angular-cli-files/plugins/raw-css-loader.js!./node_modules/postcss-loader/src??embedded!./node_modules/sass-loader/lib/loader.js??ref--14-3!./src/assets/styles/style.scss)

我尝试删除node_modules并重新安装它

Delete `package-lock.json` file.
Go to node_module folder and `run rm -rf node_modules`.
Run `npm install`

---

npm rebuild --force
npm rebuild node-sass --force
