📚 Description

It appears that 56122b7 caused a regression with 3.15 that can produce the following error. I suspect this is environment-specific. If it were widespread, I'd expect more people to be talking about it.

TypeError: The URL must be of scheme file

Making this change directly inside node_modules works for me, but @danielroe perhaps you can provide more context. If our goal is to simply resolve the dist directory, using node:path could be a safer way to do it.
