When starting AirFlow or checking dags with airflow list_dags in a clean Python 3.7 environment the following trace appears:

{dagbag.py:239} ERROR - Failed to import: /home/leo/Freelancing/Datopian/aircan/aircan/dags/api_ckan_import_to_bq.py
Traceback (most recent call last):

ModuleNotFoundError: No module named 'aircan.dependencies.google_cloud'

Steps to reproduce:

Set a clean python 3.7 environment
Install Airflow Dependencies
Install Airflow
Install aircan dependencies
Install aircan from repo (python setup.py install)
Set environment variables and airflow configurations as per this repository's README.md file
Execute airflow list_dags or launch airflow webserver

Desired behaviour:

aircan.dependencies.google_cloud should be installed correctly when installing aircan and no error message should appear.
