[Python-modules-team] Bug#896364: python-scrapy-djangoitem: scrapy_djangoitem fails to import

[Helmut Grohne]

Package: python-scrapy-djangoitem
Version: 1.1.1-1
Severity: serious
User: helmutg at debian.org
Usertags: python-import

After installing python-scrapy-djangoitem importing the module scrapy_djangoitem
into a python interpreter fails with the following error:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/scrapy_djangoitem/__init__.py", line 2, in <module>
    from django.core.exceptions import ValidationError
ImportError: No module named django.core.exceptions

The vast majority of import failures is attributed to missing dependencies.
Often times that manifests as an ImportError or ModuleNotFoundError.
Typically, dependencies should be inserted by dh-python via ${python:Depends}
or ${python3:Depends}. Thus a missing dependency can be caused by incomplete
install_requires in setup.py. Sometimes a missing dependency of a dependency
is the cause, in such cases this bug should be reassigned.
