need to know the version scheme to use. This specifies
the current PEP-recommended scheme - use ``'legacy'``

Attempt to replace one provider with another. This is typically used
when resolving dependencies from multiple sources, e.g. A requires
(B >= 1.0) while C requires (B >= 1.1).
For successful replacement, ``provider`` must meet all the requirements
which ``other`` fulfills.
:param provider: The provider we are trying to replace with.
:param other: The provider we're trying to replace.
:param problems: If False is returned, this will contain what
problems prevented replacement. This is currently
a tuple of the literal string 'cantreplace',
``provider``, ``other`` and the set of requirements
that ``provider`` couldn't fulfill.
:return: True if we can replace ``other`` with ``provider``, else
False.

Find a distribution and all distributions it depends on.
:param requirement: The requirement specifying the distribution to
find, or a Distribution instance.
:param meta_extras: A list of meta extras such as :test:, :build: and
so on.
:param prereleases: If ``True``, allow pre-release versions to be
returned - otherwise, don't return prereleases
unless they're all that's available.
Return a set of :class:`Distribution` instances and a set of
problems.
The distributions returned should be such that they have the
:attr:`required` attribute set to ``True`` if they were
from the ``requirement`` passed to ``find()``, and they have the
:attr:`build_time_dependency` attribute set to ``True`` unless they
are post-installation dependencies of the ``requirement``.
The problems should be a tuple consisting of the string
``'unsatisfied'`` and the requirement which couldn't be satisfied
by any distribution known to the locator.
