I get the following error when I try to create a new project. I've updated ng cli after reading this issue, but I'm still getting the error.

Looks like the issue is caused by a karma-jasmine-html-reporter release, were they dropped support for jasmine-core version 3.7 in a minor version.

Removing the lower bounds of a peerDependency should be considered a breaking changed due to NPM 7 new peer dependencies behaviour.

As a workaround you can do the following;

ng new --skip-install
Open package.json and bump jasmine-core to `~3.8.0`
npm i
