Packaging multiple Python Files: Getting Import error

Question

I am trying to figure out how to package a python project so that I can distribute it to some co-workers. When I run python setup.py sdist --formats=zip it creates a zip that I can pip install but when I run the file it can't import the class files I created.

Here is my file structure for the project (probably not correct, but I didn't fully structure this project with packaging in mind):

├── README.md
├── requirements.txt
├── scanner
│  ├── __init__.py
│  ├── __pycache__
│  │  ├── googleSheets.cpython-35.pyc
│  │  ├── merakiJsonHandler.cpython-35.pyc
│  │  └── wifiTester.cpython-35.pyc
│  ├── credentials.json
│  ├── googleSheets.py
│  ├── info.json
│  ├── merakiJsonHandler.py
│  ├── scan.py
│  ├── whatWap.py
│  └── wifiTester.py
└── setup.py

''scan.py'' is our "main" script that brings together all the classes. Here is what my setup.py looks like:

import setuptools
setuptools.setup(name='att-scanner',
 version='0.1',
 description='Meraki Wap/Wifi Scanner',
 author='jsolum',
 author_email='*****',
 license='MIT',
 packages=setuptools.find_packages(),
 entry_points={
 'console_scripts' : [
 'mws = scanner:scan.py',],},
 install_requires=['pyspeedtest', 'requests', 'gspread', 'oauth2client',],
 include_package_data=True)

And here is my error:

Traceback (most recent call last):
 File "//anaconda/bin/mws", line 7, in <module>
 from scanner import scan
 File "//anaconda/lib/python3.5/site-packages/scanner/__init__.py", line 1, in 
<module>
 from googleSheets import SheetsController
ImportError: No module named 'googleSheets'

Why can't scan.py import googleSheets.py and what do I do to make it import that and my other classes?

Answer 1

from googleSheets import SheetsController is an absolute import statement, so once your package is installed, you need to either use the package name:

from scanner.googleSheets import SheetsController

Or a relative import statement

from .googleSheets import SheetsController

• jsolum: facepalm you're right. I thought I checked that! Currently I am getting an error that says `` sys.exit(scan()) TypeError: 'module' object is not callable``. I am curious to why it's trying to call scan.py. Does scan need to be renamed to main? (I think I read something like that earlier when I was troubleshooting).
• Peter Gibson: @JamesSolum I'm not 100% sure, but It looks like your entry point is set to the module, rather than a function in the module. Try something like scanner.scan:main
• jsolum: I just saw this comment now, but yes that was it! Thanks!
