[FIXED] Error when creating a new project using Angular CLI 13.1.0

Issue

I’m getting the following error when creating a new project using Angular CLI v13.1.0

I’m using Node JS version 16.13.1 and npm version 8.1.2

I tried clearing npm cache with –force, also reinstalled Node JS. Still no luck.

Solution

So I solved it like this:

  1. I created the project using ng new. It then created the project but threw an error when installing the dependencies.

  2. Then I manually edited the package.json file and replaced all angular package versions 13.0.0 with 13.1.0 and ran npm i.

After that, all packages were installed perfectly fine and I could run ng serve.
