throw new Error('Could not find local “typescript” package.')

Question

I am getting this error when I upgraded angular from version 5.2 to 11. I have typescript installed in the package.json file. But when i run the app, I keep getting the error:throw new Error('Could not find local "typescript" package.')

I have also referred to the below issue but that did not help me.

Could not find local "typescript" package.The "@ngtools/webpack" package Angular 2

Answer 1

The solution was to create a new project to upgrade the app. just copied the source file and the then upgraded the dependencies. also changed the code in the components where ever needed. i was able to upgrade my app successfully.
