Cross-Platform Pipenv Lock GitHub Workflow
The lock file produced by pipenv is specific to the platform
it was created on. This can mean that platform specific dependencies
can be missing after running pipenv sync on another platform.
You cannot ask pipenv to produce a cross-platform lock file, instead
you must run pipenv lock --keep-outdated on each platform to append
their platform specific dependencies to the lock file without removing
the previous platforms.
This workflow (.github/workflows/cross-platform-lock.yml) is a example
that produces a cross-platform Pipfile.lock whenever it detects a change
to the dependencies, and recommits the cross-platform lock file back to
the repository.
