There is something amiss with CLI 9.1.4 and Angular 9.1.5.
run: npm install @angular/core@9.1.4 @angular/animations@9.1.4 @angular/common@9.1.4 @angular/forms@9.1.4 @angular/platform-browser@9.1.4 @angular/router@9.1.4 @angular/platform-browser-dynamic@9.1.4 @angular/compiler@9.1.4 @angular/compiler-cli@9.1.4 @angular/language-service@9.1.4

then ng build

Worked for me

@komalgmore, can you try to update to latest version Angular and Angular CLI? If, the problem persists kindly setup a minimal repro.

You can read here why this is needed. A good way to make a minimal repro is to create a new app via ng new repro-app and adding the minimum possible code to show the problem. Then you can push this repository to github and link it here.

This might be related to your directory structure so its really important to get an accurate repro to diagnose this.

@komalgmore, can you also provide the output of ng version?
