Python distributed by Apple's Command Line Tools has this special scheme that's used when: * This is a framework build. * We are installing into the system prefix. This does not account for ``pip install --prefix`` (also means we're not installing to the system prefix), which should use ``posix_prefix``, but logic here means ``_infer_prefix()`` outputs ``osx_framework_library``. But since ``prefix`` is not available for ``sysconfig.get_default_scheme()``, which is the stdlib replacement for ``_infer_prefix()``, presumably Apple wouldn't be able to magically switch between ``osx_framework_library`` and ``posix_prefix``. ``_infer_prefix()`` returning ``osx_framework_library`` means its behavior is consistent whether we use the stdlib implementation or our own, and we deal with this special case in ``get_scheme()`` instead. osx_framework_library)_AVAILABLE_SCHEMESrr r r A/tmp/pip-build-red6nood/pip/pip/_internal/locations/_sysconfig.py _should_use_osx_framework_prefixsrcCsvtr tdStrdStjjdtj}|tkr6|StjjtkrJtjjStjd}|tkrb|StjtkrrtjSdS)a!Try to find a prefix scheme for the current platform.
