导入具有相同基本软件包名称的软件包

问题描述

我有一个大图书馆要拆分.有软件包:hdx.datahdx.facadeshdx.utilities

I have a large library I want to split up. There are packages:hdx.datahdx.facadeshdx.utilities

我想将hdx.utilities移到一个单独的项目hdx-python-utilities(在PyPi上)，然后将其作为必需项添加到该项目中，并带有hdx.data和hdx.facades包(hdx-python-api) .问题是在项目hdx-python-api中执行from hdx.utilities.session import get_session时得到ImportError: No module named 'hdx.utilities'.

I want to move hdx.utilities to a separate project hdx-python-utilities (on PyPi) and then add it as a requirement to the project with the packages hdx.data and hdx.facades (hdx-python-api). The problem is that I get ImportError: No module named 'hdx.utilities' when doing from hdx.utilities.session import get_session in the project hdx-python-api.

是否有任何方法可以使它在Python 3+和2.7中都可以工作(在其中两个中都没有重命名顶级包名称hdx)，从而允许hdx-python-api和hdx-python-utilities都可以在任何项目中工作会安装它们吗?

Is there any way to make this work in both Python 3+ and 2.7 (without renaming the top level package name hdx in either of them) allowing both hdx-python-api and hdx-python-utilities to work in any project that installs them?

推荐答案

制作命名空间包的三种方法:

• 本机(Python 3.3)
• pkgutil样式(Python 2和3，与本机兼容)
• pkg_resources样式(与以上版本不兼容，不建议使用，不推荐)

为Python 2和3创建命名空间包的推荐方法是 pkgutil样式的名称空间包:

The recommended way of doing namespaced packages for Python 2 and 3 are pkgutil-style namespace packages:

您将为hpx-python-api

setup.py
hpx/
    __init__.py     # namespace init, see content below
    data/
        __init__.py
        ...
    facades/
        __init__.py
        ...

以及hpx-python-utilities

setup.py
hpx/
    __init__.py     # namespace init, see content below
    utilities/
        __init__.py
        ...

名称空间包的两个__init__.py文件仅需要包含以下内容:

The two __init__.py files for the namespace package needs to contain only the following:

__path__ = __import__('pkgutil').extend_path(__path__, __name__)
