Expected Behavior

after updating create-next-app to 12.1.1, npx create-next-app appname is not creating the Next app

To Reproduce

I tried npx create-next-app@latest appname but it's throwing the same error.

even I tried to uninstall the create-next-app & reinstalled it but it's throwing the same error.

and I install yarn globally then npx create-next-app appname run command properly without any error

[git-no]

I have the same issue. Can not run npx create-next-app@latestwithout error/break.
Node 16.14.2, no yarn installed.

[JorneSaenen]

"npx create-next-app@latest --use-npm"

[W9968]

"npx create-next-app@latest --use-npm"

this does not help at least for my case it just stuck installing without any progress for about 20+ minutes

Hi, this has been fixed in the latest version of Next.js v12.1.2 please give it a try! Note: this may require running with @latest e.g. npx create-next-app@latest. Specific PR this was fixed in can be seen here #35608
