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

Question

我在python中有一个项目，如果通过“python do.py”调用它可以正常工作，但是当我在开发模式下安装它并且脚本导入我的模块时，我得到一个“ModuleNotFoundError”。这是我的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',
        ]
    },
)

这是结构（主要和模块在do /中）：

[树] [1]

这是我使用python do.py时的调用：

(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.

并且，这是我在开发模式下运行时的输出：

(python-cli) λ do
Traceback (most recent call last):
  File "C:\Users\carlo\Envs\python-cli\Scripts\do-script.py", line 11, in <module>
    load_entry_point('do-pack', 'console_scripts', 'do')()
  File "c:\users\carlo\envs\python-cli\lib\site-packages\pkg_resources\__init__.py", line 572, in load_entry_point
    return get_distribution(dist).load_entry_point(group, name)
  File "c:\users\carlo\envs\python-cli\lib\site-packages\pkg_resources\__init__.py", line 2755, in load_entry_point
    return ep.load()
  File "c:\users\carlo\envs\python-cli\lib\site-packages\pkg_resources\__init__.py", line 2408, in load
    return self.resolve()
  File "c:\users\carlo\envs\python-cli\lib\site-packages\pkg_resources\__init__.py", line 2414, in resolve
    module = __import__(self.module_name, fromlist=['__name__'], level=0)
  File "c:\dropbox\dropbox\projects\python\do-pack\do\do.py", line 3, in <module>
    import skeleton
ModuleNotFoundError: No module named 'skeleton'

谢谢。

Answer 1

1. 确保do文件夹中包含__init__.py文件。 <击> 2。将“do”添加到setup.py 中的packages= kwarg 看起来您正在使用find_packages()
处理这个问题

工作示例

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

setup.py

来自setuptools导入设置

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

do.py

def run():
    print('Completed')

从app /文件夹中，安装并运行：

>>> pip install .
>>> do
Completed

更新

我在本地运行你的代码，看起来它可能只是代码中的python相对/绝对导入问题。

如果您使用完全绝对导入，它应该起作用：

do.py

而不是

import skeleton
import licenses
import setup_config

您需要使用绝对或相对包导入

# 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
