“AttributeError：'module'对象没有安装包的属性”

标签： python setuptools setup.py

我有一个包含以下内容的项目：

proj
├── src
│   ├── scriptA.py
│   ├── scriptB.py
│   └── __init__.py
├── LICENCE
├── README.md
└── setup.py

我正在关注this guide将此项目打包为PiPY。 setup.py文件如下所示：

#!/usr/bin/python3
# coding=utf8

from setuptools import setup

setup(
    name = "proj",
    version = "0.2",
    packages = ['src'],
    install_requires=[],
    entry_points={
        'console_scripts': [
            'scriptA=src:scriptA',
            'scriptB=src:scriptB'
        ],
    },

    # metadata for upload to PyPI
    author = "Luís",
    author_email = "luis@mail.com",
    description = "Some package",
    license = "EUPL v1.1",
    keywords = "pip package",
    url = "https://some.place.com",   # project home page, if any
    classifiers = [
        "Programming Language :: Python",
        "Programming Language :: Python :: 3",
        "Development Status :: 4 - Beta",
        "Environment :: Console",
        "Intended Audience :: Science/Research",
        "License :: OSI Approved :: European Union Public Licence 1.1 (EUPL 1.1)",
        "Operating System :: OS Independent",
        "Topic :: Scientific/Engineering :: GIS"
        ],


    # could also include long_description, download_url, classifiers, etc.
)

__init__.py文件包含以下内容：

__all__ = ["scriptA", "scriptB"]

脚本只打印短信。这是scriptA.py：

def main():
    print ("This is scriptA!")

main()

这些包正在成功建立：

但是当我运行其中一个脚本时，我得到以下内容：

(test_p3)$ scriptA
Traceback (most recent call last):

    entry = getattr(entry,attr)
AttributeError: 'module' object has no attribute 'scriptA'

During handling of the above exception, another exception occurred:

ImportError: <module 'src' from '/home/desouslu/.virtualenvs/test_p3/lib/python3.4/site-packages/hex_utils-0.2-py3.4.egg/src/__init__.py'> has no 'scriptA' attribute

究竟是什么导致了这个错误？

2 个答案:

答案 0 :(得分：2)

在您的情况下，它会在模块scriptA中查找src可调用。

查看docs，entry_points应定义为：

entry_points={
    'console_scripts': [
        'scriptA=src.scriptA:main_func',
        'scriptB=src.scriptB:main_func'
    ],
},

答案 1 :(得分：-1)

您应该在SELECT COUNT( DISTINCT p.product_id ) AS total FROM bh_product p ,bh_product_description pd,bh_product_to_store p2s where p.product_id = pd.product_id and p.product_id = p2s.product_id ; 跟随link
