与 setup.py 一起安装的脚本引发 ImportError

Question

I am trying to add a runnable script for my project with setup.py . I added it to the scripts= argument of setup . The script works fine when I run it from the project, ./solver . I install it with sudo python setup.py install , and try to run it with solver , but I get ImportError: No module named 'model' . How do I correctly install and run my script with setuptools?

SOLVER/
    solver/
        model/
            __init__.py
        view/
             __init__.py
        controller/
             __init__.py
        __init__.py
        main.py 
        solver <-- starts the app
    setup.py
    README.md

setup.py :

#!/usr/bin/env python3
import os
from setuptools import setup, find_packages

setup(
    name='SOLVER',
    version='1.0.0',
    description='SOLVER app test',
    author=['me'],
    license='BSD',
    classifiers=['Programming Language :: Python :: 3 :: Only'],
    packages=['solver'],
    #packages=find_packages(exclude=["doc", "tests"]),
    install_requires=['numpy>=1.10.4'],
    scripts=['solver/solver'],
)

solver :

#!/usr/bin/env python3

from solver import main
main.gui_mode()

You need to list all the packages, including the sub-packages, in the packages argument. You can use find_packages to generate that list for you. Currently, you're just installing the Python files in the solver/ directory.

from setuptools import setup, find_packages

setup(
    ...
    packages=find_packages(),
    ...
)

You should also use entry_points rather than scripts , especially when all your script does is import and call one function. Setuptools will build scripts from the entry points that use the correct Python binary for the env they were installed in.

setup(
    ...
    packages=find_packages(),
    entry_points={
        'console_scripts': [
            'solver=solver.main:gui_mode'
        ]
    ...
    }

You can install your package in development mode to get your script, rather than writing it yourself.

pip install -e .

You should use pip to install to the system as well. It keeps track of what was installed so you can uninstall it later.

pip install .
