[Resolved] An unhandled exception occurred: cannot find module '@angular-devkit/build-angular/package.json'
Hello,
I have a cms template with angular 9. I downloaded it from the CoreUI website and after installed Node.js and Angular CLI I ran the command below :
ng serve --port 4201 -o
But I got an error as below:
An unhandled exception occurred: Cannot find module '@angular-devkit/build-angular/package.json'

You can try one in two option below, I hope it works for you.
1. Option 1
Install

as a dev dependency. This package is newly introduced in Angular 6.0npm install --save-dev @angular-devkit/build-angular
OR
yarn add @angular-devkit/build-angular --dev
2. Option 2
You need to update npm.
npm update
