运行通过使用 stdeb 创建的 deb 安装的 python 脚本时出现 ModuleNotFoundError

Question

I've build a really simple Python project I'm packaging into a.deb file for installation. I've got the building of.deb working, but when I run my script via it's command, I get a ModuleNotFoundError.

My project structure is as follows:

setup.py
hello
  |
  | - __init.py__
  | - hello.py
  | - world.py

setup.py

import os
from setuptools import setup, find_packages
setup(
    name = "hello_py",
    version = "1.3",
    author = "Sion Hughes",
    author_email = "",
    description = "It's a simple hello world, but this time with 2 python file",
    license = "",
    url = " ",
    packages=find_packages(),
    entry_points = {
        'console_scripts' : ['hello = hello.hello:main',
        'command-name = hello.hello:main']
    },
    classifiers=[
        "License :: OSI Approved :: BSD License",
    ],
)

hello.py

#!/usr/bin/env python3
import world

def main():
    print("Hello, this is Siôn's python script")
    world.hello()

if __name__ == "__main__":
    main()

world.py

#!/usr/bin/env python3

def hello():
    print("Hello from another Python file")

All runs fine locally, but when I run using hello command, I get the following error:

# hello
Traceback (most recent call last):
  File "/usr/bin/hello", line 11, in <module>
    load_entry_point('hello-py==1.3', 'console_scripts', 'hello')()
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 490, in load_entry_point
    return get_distribution(dist).load_entry_point(group, name)
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 2854, in load_entry_point
    return ep.load()
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 2445, in load
    return self.resolve()
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 2451, in resolve
    module = __import__(self.module_name, fromlist=['__name__'], level=0)
  File "/usr/lib/python3/dist-packages/hello/hello.py", line 5, in <module>
    import world
ModuleNotFoundError: No module named 'world'

Where am I going wrong to get this working? Thanks in advance.

Update: Forgot to say in the initial post, I want to be able to run the scripts in their local directory for development purposes too, not just always run via installed.deb

Answer 1

Instead of import world in hello.py, try using import.world .
