Cannot find module '@angular-devkit/build-angular/package.json'

Hey,

I have ionic project cloned from the internet, I have installed all the requirements.
when I run `ionic serve` inside the project folder I got this error.

`> ng.cmd run app:serve --host=localhost --port=8100
[ng] An unhandled exception occurred: Cannot find module '@angular-devkit/build-angular/package.json'

The Ionic CLI will exit. Please check any output above for error details.`

any help?

The reported entry point is `ionic serve`, which invokes `ng.cmd run app:serve`; begin by reproducing that command in the cloned project and inspecting the installed Angular CLI dependencies around the missing `@angular-devkit/build-angular/package.json`. Done means the project serves successfully without the missing-module error.
