如何使用具有相同名称的setuptools软件包和ext_modules?

问题描述

我的Python C Extension项目获得了以下文件结构:

I got the following file structure for my Python C Extension project:

.
├── setup.py
├── source
    ├── cppimplementation
    │   └── fastfile.cpp
    └── fastfilepackage
        ├── __init__.py
        └── version.py

我使用以下setup.py文件:

from setuptools import setup, Extension

setup(
        name= 'fastfilepackage',
        version= '0.1.1',
        package_dir = {
            '': 'source',
        },

        packages = [
            'fastfilepackage',
        ],

        ext_modules= [
            Extension(
                'fastfilepackage',
                [
                    'source/cppimplementation/fastfile.cpp',
                ]
            )
        ],
    )

我通过以下方式安装它们:

I install them with:

$ pip3 --version
pip 19.1.1 (python 3.6)

$ python3 --version
Python 3.6.7

$ pip3 list
Package                Version      
---------------------- -------------
wheel                  0.33.1        
setuptools             40.8.0        
...

fastfilepackage$ pip3 install .

问题在于，当我安装它时，我的Python C Extension模块被fastfilepackage/version.py和fastfilepackage/__init__.py覆盖，即，安装后，我得到了以下信息:

The problem is that when I install it, my Python C Extension module is overridden by fastfilepackage/version.py and fastfilepackage/__init__.py, i.e, after installing it, I got the following:

import fastfilepackage
print( dir( fastfilepackage ) )
# prints ['__builtins__', '__cached__', '__doc__', '__file__', '__loader__', 
#         '__name__', '__package__', '__path__', '__spec__', '__version__',
#         'version']

即，没有source/cppimplementation/fastfile.cpp导出的FastFile类，但是它具有fastfilepackage/version.py和fastfilepackage/__init__.py文件.

i.e., no FastFile class exported by source/cppimplementation/fastfile.cpp, but it has the fastfilepackage/version.py and fastfilepackage/__init__.py files.

这是已安装的文件结构:

This is the installed file structure:

.
└── dist-packages
    ├── fastfilepackage
    │   ├── __init__.py
    │   ├── __pycache__
    │   │   ├── __init__.cpython-36.pyc
    │   │   └── version.cpython-36.pyc
    │   └── version.py
    ├── fastfilepackage-0.1.1.dist-info
    │   ├── INSTALLER
    │   ├── LICENSE.txt
    │   ├── METADATA
    │   ├── RECORD
    │   ├── top_level.txt
    │   └── WHEEL
    └── fastfilepackage.cpython-36m-x86_64-linux-gnu.so

但是，如果我从安装文件中删除了package_dir = { '': 'source', },和packages = [ 'fastfilepackage', ],行，则说明我的Python C Extension模块已正确安装:

But if I remove the lines package_dir = { '': 'source', }, and packages = [ 'fastfilepackage', ], from my setup file, then, my Python C Extension module is correctly installed:

import fastfilepackage
print( dir( fastfilepackage ) )
# prints ['FastFile', '__doc__', '__file__', '__loader__', '__name__', 
#         '__package__', '__spec__']

即，它具有source/cppimplementation/fastfile.cpp导出的FastFile类，但没有fastfilepackage/version.py和fastfilepackage/__init__.py文件.

i.e., it has the FastFile class exported by source/cppimplementation/fastfile.cpp, but it does not have the fastfilepackage/version.py and fastfilepackage/__init__.py files.

这是已安装的文件结构:

This was the installed file structure:

.
└── dist-packages
    ├── fastfilepackage-0.1.1.dist-info
    │   ├── INSTALLER
    │   ├── LICENSE.txt
    │   ├── METADATA
    │   ├── RECORD
    │   ├── top_level.txt
    │   └── WHEEL
    └── fastfilepackage.cpython-36m-x86_64-linux-gnu.so

如何在setup.py下放置ext_modules和packages以使用相同的程序包名称，而又不覆盖另一个?

How can I put ext_modules and packages to use the same package name under my setup.py without one overriding the other?

推荐答案

您不能.第一个进口胜利.您不能具有相同名称的脚本/模块/软件包/扩展名-一个覆盖所有其他名称.

You cannot. The first one imported wins. You cannot have scripts/modules/packages/extensions with the same name — one overrides all others.

但是您可以将一个人带入另一个人.将扩展名命名为fastfilepackage.fastfilepackage，您可以import fastfilepackage导入Python包，并import fastfilepackage.fastfilepackage导入扩展；或from fastfilepackage import fastfilepackage.

But you can to have one inside another. Make your extension named fastfilepackage.fastfilepackage and you can import fastfilepackage to import the Python package and import fastfilepackage.fastfilepackage to import the extension; or from fastfilepackage import fastfilepackage.
