Until this is fixed, how can I create a new project? Is there a way to pass --legacy-peer-deps to npm?
ng new --minimal still works, which is better than nothing I guess.

You can you —skip-install to skip invoking npm during the project creation. You can then run npm install manually after the project has been created

Not really working, but npm install --force works.

I have an issue similar when install and create a new project

Downgrade npm from 7 to 6 using npm install -g npm@6

Wait, why is @alan-agius4 closing this issue? You guys need to check if there is a workaround instead of "IGNORING" this issue.

We didn’t ignore this, we closed it because it was solved via PR #20720
