`' File "c:\python27\lib\site-packages\billiard\spawn.py", line 338, in _fixup_main_from_name ' File "c:\python27\lib\site-packages\billiard\spawn.py", line 165, in spawn_main module' object has no attribute 'spec' module' object has no attribute 'spec' if getattr(current_main.spec, "name", None) == mod_name:

at this point there is a check for a nonexistent attribute https://github.com/celery/billiard/blob/ca3220ba4596ac7bb03f64b80e91878353fc5be1/billiard/spawn.py#L264

in another place there is no check and an error occurs https://github.com/celery/billiard/blob/ca3220ba4596ac7bb03f64b80e91878353fc5be1/billiard/spawn.py#L338
