The preparation step for these needs metadata for the packages to be generated, either using PEP 517 or using the legacy `setup.py egg_info`. NOTE from @pradyunsg (14 June 2019) I expect SourceDistribution class will need to be split into `legacy_source` (setup.py based) and `source` (PEP 517 based) when we start bringing logic for preparation out of InstallRequirement into this class. c C s | j �� S �N)�reqZget_dist)�self� r �M/usr/lib/python3.8/site-packages/pip/_internal/distributions/source/legacy.py� get_pkg_resources_distribution s z1SourceDistribution.get_pkg_resources_distributionc C s< | j �� | j jo|}|r$| �|� | j �� | j �� d S r )r Zload_pyproject_tomlZ use_pep517�_setup_isolationZprepare_metadataZ assert_source_matches_version)r �finderZbuild_isolationZshould_isolater r r � prepare_distribution_metadata s z0SourceDistribution.prepare_distribution_metadatac s� � �fdd�}t � �j_�jj�|�jjdd� �jj��jj�\� }� rT|d� � |r�t�d�j� t�dd� t t t |���� �jj�4 t d �}�jj}|�|�� |�� }W 5 Q R X W 5 Q R X �jj�|�\� }� r�|d � � �jj�||d d � d S ) Nc s6 d}|j �j| d�dd� t� �D ��d�}t|��d S )NzZSome build dependencies for {requirement} conflict with {conflicting_with}: {description}.z, c s s | ]\}}d ||f V qdS )z%s is incompatible with %sNr )�.0Z installedZwantedr r r � <genexpr>3 s �zPSourceDistribution._setup_isolation.<locals>._raise_conflicts.<locals>.<genexpr>)Z requirement�conflicting_with� description)�formatr �join�sortedr )r Zconflicting_reqs� format_stringZ error_message�Z conflictingr r r �_raise_conflicts+ s � ��z=SourceDistribution._setup_isolation.<locals>._raise_conflictsZoverlayz Installing build dependenciesz"PEP 517/518 supported requirementsz4Missing build requirements in pyproject.toml for %s.z`The project does not specify a build backend, and pip cannot fall back to setuptools without %s.z and z#Getting requirements to build wheelzthe backend dependenciesZnormalz Installing backend dependencies)r r Z build_envZinstall_requirementsZpyproject_requiresZcheck_requirementsZrequirements_to_check�loggerZwarningr �map�reprr r Zpep517_backendZsubprocess_runnerZ get_requires_for_build_wheel)r r r ZmissingZrunnerZbackendZreqsr r r r * sP ����� � �z#SourceDistribution._setup_isolationN)�__name__� __module__� __qualname__�__doc__r r r r r r r r s r ) ZloggingZpip._internal.build_envr Z pip._internal.distributions.baser Zpip._internal.exceptionsr Z pip._internal.utils.subprocessr Z getLoggerr r r r r r r �<module> s
