I have tried to fix these errors by upgrading npm but after npm upgrade, I got the same issues

Answer 1

I was in same problem. after much try and error, i solved as follows. install yarn. then run the following code ng set --global packageManager=yarn and then run ng new project_name this way, i solved the problem

If at any point you want to revert back to npm run this: ng config -g cli.packageManager npm
