ImportError when using console_scripts in setuptools

Question

I am trying to build a program called dnsrep in Python, I am using setuptools so that I can call the dnsrep module without using the command python dnsrep. The setup.py script I wrote is given below:

from setuptools import setup, find_packages

setup(
    name='dnsrep',
    version='0.1',
    description='Program that gives a reputation score to url\'s\n.',
    entry_points = {
        'console_scripts': ['dnsrep = dnsrep:main']
    },
    zip_safe=True,
)

I install the module by using the command:

python setup.py install

My module gets registered but when I run it I get the error:

Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/2.7/bin/dnsrep", line 9, in <module>
    load_entry_point('dnsrep==0.1', 'console_scripts', 'dnsrep')()

ImportError: No module named dnsrep

Answer 1

You have to install your python script, before you can call it via your defined entry point

This is my dummy project:

dnsrep/
├── dnsrep.py
└── setup.py

This is how setup.py looks like:

from setuptools import setup
setup(
    name='dnsrep',
    version='0.1',
    description='Program that gives a reputation score to url\'s\n.',
    py_modules=['dnsrep'],
    entry_points = {
        'console_scripts': ['dnsrep = dnsrep:main']
    },
    zip_safe=True,
)

Note the argument py_modules=['dnsrep'], which installs dnsrep.py as a new module.

Finally, this is my dummy implementation of dnsrep.py:

from __future__ import print_function

def main():
    print("Hey, it works!")

After installing, everything works as expected and $ dnsrep prints: Hey, it works!
