This preparation is done by ``pip.operations.prepare``.

Note that req.link may still be None - if the requirement is already installed and not needed to be upgraded based on the return value of _is_upgrade_allowed(). If preparer.require_hashes is True, don't use the wheel cache, because cached wheels, always built locally, have different hashes than the files downloaded from the index server and thus throw false hash mismatches.
