Can't build project made with Angular CLI and SCSS

Question

1. Created a new project with Angular CLI
2. Selected SCSS
3. Runs well on localhost with ng serve
4. Can't run build, it throws an error, only with SCSS.

Angular CLI version:

Angular CLI: 13.0.2
Node: 14.18.2
Package Manager: npm 6.14.15
OS: linux x64

Angular: 
... 

Package                      Version
------------------------------------------------------
@angular-devkit/architect    0.1300.2 (cli-only)
@angular-devkit/core         13.0.2 (cli-only)
@angular-devkit/schematics   13.0.2 (cli-only)
@schematics/angular          13.0.2 (cli-only)

Here is the error log:

Answer 1

Step 1: $ npm cache clean --force

Step 2: Delete node_modules by $ rm -rf node_modules (rmdir /S /Q node_modules in windows) folder or delete it manually by going into the directory and right-click > delete / move to trash. If are not updating your packages you can delete the package-lock.json file too.

Step 3: npm install

To start again,

$ npm start 

This worked for me. Hopes it works for you too.

PS: Still if it is there, kindly check the error it is displaying in read and act accordingly. This error is specific to node.js environment.
