Thank you for contributing to Pipenv!

The issue

Trying to get some improved windows support and figure out why those 3 tests are failing in the CI.

The fix

How does this pull request fix your problem? Did you consider any alternatives? Why is this the best solution, in your opinion?

Not sure if it does.

The checklist

• [ ] Associated issue
• [ ] A news fragment in the news/ directory to describe this fix with the extension .bugfix, .feature, .behavior, .doc. .vendor. or .trivial (this will appear in the release changelog). Use semantic line breaks and name the file after the issue number or the PR #.

We have to think on conditionally vendoring this module on Windows only packages. Otherwise, everyone has this vendored regardless of the OS.

Nothing really indicates to me that this is necessary.
