I found, what I feel is, a better solution. After running the ng new - go into package.json and simply change

"jasmine-core": "~3.7.0",

to

"jasmine-core": "~3.8.0",

and then run npm install afterwards.

I have faced the same issue recently and i got to know this from an online instructor. you should have phrase the question neatly, anyways

This error is caused by an npm 7 issue. The Angular team recommends to use npm 6 for now. so downgrade the npm 7 to npm 6 for now

npm install -g npm@6

or

An alternative can be to run ng new with the --skipInstall flag, and then install the dependencies with npm install --legacy-peer-deps.
