Problem description
Currently, string imports are not possible outside of packages.
Minimal reproducible example
The following code snippet executed from a script or Jupyter notebook cell raises an
AttributeError: 'NoneType' object has no attribute '__package__'
The trace back reveals that the exception is thrown in
src/dependency_injector/providers.pyx in dependency_injector.providers._resolve_calling_package_name()
.Proposal for solution
In case the module in
dependency_injector.providers._resolve_calling_package_name
isNone
, the package should also beNone
. The subsequent call toimportlib.import_module
will handle the situation properly.
