Error detecting the selected package manager (yarn)

Describe the bug or question
When I run npx create-single-spa and I select "yarn" when asked which package manager I want to use I get this warning message: "Error detecting the package manager. Falling back to npm."

The selected package manager (yarn) should be used instead of falling back to npm
