Hi,

Not sure about the solution but you can try this.

  1. Delete Node_Modules folder.
  2. Run npm install again

Do same with the Platform if you are using android or ios platform to test.

If it doesn’t work then there might be a dependency related issue in your package.json file like including “angular/form” module in your dependencies.

I hope it works out for you.

I am also getting exactly the same issue while running IONIC SERVE command, deleted node_modules and ran NPM INSTALL multiple times, still getting the issue. is anyone else faced the same?

I got the same error, running npm install twice has resolved the issue, and could able to serve it. Thanks gaurav. I guess during the starting of my app some npm modules could not download completely, I observed from the output that, it has downloaded couple of modules each time i hit npm install.

Regards,
