title: Module parse failed: Identifier 'ɵngcc0' has already been declared ANGULAR
body: <p>Good day everyone, I'm doing a personal project but at the moment of using:
  import {NgForm} from '@ angular / forms';
  The error appears, I've tried the command of &quot;npm ci&quot; and then re-installing node_modules, update the Node but the problem persists.
  I did the respective validation in app.module.ts when importing the library but the problem still persists.
  Any help, guidance or advice I really appreciate</p>
  <pre><code>Error: ./node_modules/@angular/forms/__ivy_ngcc__/fesm2015/forms.js 27:12
  Module parse failed: Identifier 'ɵngcc0' has already been declared (27:12)
  File was processed with these loaders:
   * ./node_modules/@angular-devkit/build-angular/src/babel/webpack-loader.js
   * ./node_modules/@ngtools/webpack/src/ivy/index.js
  
  You may need an additional loader to handle the result of these loaders.
