why am i getting a tox import error before the dependencies are installed

Question

in my django project, I have a an __init__.py file that imports celery, I suspect this may be causing tox to complain.

/testproj/testproj/ ____init___.py

from .celery import app as celery_app

when I run tox, the tests successfully run, but I see this error.

File "/dir/work/testproj/testproj/celery.py", line 2, in <module>
from celery import Celery
ImportError: cannot import name Celery
mobilereports installed: amqp==1.4.9,anyjson==0.3.3,appdirs==1.4.0,Babel==2.3.4,billiard==3.3.0.23,cached-property==1.3.0,celery==3.1.24

What I find strange is that the import error is above the actual imports where celery gets imported.

Why am I getting this error? Celery is in my requirements.txt which is being installed by tox as you can see above, so why would I get an import error before the deps actually get installed?

tox.ini

[tox]
envlist = mobilereports
skipsdist = True

[env]
commands = ./runtests.sh 


setenv =
    DJANGO_SETTINGS_MODULE=testproj.settings
    PYTHONPATH={toxinidir}

[base]
deps =
    -r{toxinidir}/requirements.txt

[env:testproj]
basepython = python3
deps =
    {[base]deps}

Try renaming your celery.py file to something else. It might be masking the celery module installed via requirements (so the from celery import Celery line could be importing from the module itself).
