Python开发模式：ModuleNotFoundError：没有名为xxxx的模块

Question

i have a project in python that works just fine if call it by "python do.py", but when i install it in Development Mode and the script imports my modules i get a "ModuleNotFoundError". This is my setup.py

from setuptools import setup, find_packages


with open('README.rst') as f:
    readme = f.read()

with open('LICENSE') as f:
    license = f.read()

setup(
    name='do-pack',
    version='0.1dev',
    description='A command-line tool to create python packages',
    long_description=readme,
    author='Carlos Montecinos Geisse',
    author_email='carlos.w.montecinos@gmail.com',
    url='https://github.com/wilfredinni/do-pack',
    license=license,
    packages=find_packages(exclude=('tests', 'docs')),
    include_package_data=True,
    install_requires=['click'],
    python_requires='>=3',
    entry_points={
        'console_scripts': [
            'do = do.do:main',
        ]
    },
)

This is the structure (main and modules are in do/):

[tree][1]

This is the call when i use python do.py:

(python-cli) λ python do.py
Usage: do.py [OPTIONS] COMMAND [ARGS]...

  Simple CLI based script to make your Repository Structure.

Options:
  --help  Show this message and exit.

Commands:
  assistant  A step by step assistant.
  create     creates an empty proyect structure.

and, this is the output when i run it in development mode:

(python-cli) λ do
Traceback (most recent call last):
  File "C:\Users\carlo\Envs\python-cli\Scripts\do-script.py", line 11, in <module>

  File "c:\dropbox\dropbox\projects\python\do-pack\do\do.py", line 3, in <module>
    import skeleton
ModuleNotFoundError: No module named 'skeleton'

Thank you.

1. Make sure the do folder has an __init__.py file inside. 2. Add 'do' to the packages= kwarg in your setup.py Looks like you are handling that ok with find_packages()

Working Example

+ app
|+ do
 |+ __init__.py
 |+ do.py

setup.py

from setuptools import setup

setup(
    name="cliapp",
    version='0.1',
    packages=['do'],
    entry_points='''
        [console_scripts]
        do=do.do:run
    ''',
)

do.py

def run():
    print('Completed')

From app/ folder, install and run:

>>> pip install .
>>> do
Completed

I ran your code locally and looks like it might just be a python relative/absolute import issues inside your code.

If you use full absolute imports it should work:

do.py

Instead of

import skeleton
import licenses
import setup_config

You need to use absolute or relative package imports

# Absolute
from do import skeleton
from do import licenses
from do import setup_config

# Relative
from . import skeleton
from . import licenses
from . import setup_config
