如何安装具有自定义依赖项的自定义python包? [英] How to install my custom python package with its custom dependencies?

问题描述

我想找到一种方法来安装自己的python软件包，该软件包依赖于其他自定义python软件包.

I would like to find a way to install my own python package which depends on other custom python packages.

我按照本指南创建了自己的python软件包:>://://python-packaging .readthedocs.iao/zh/latest/

I followed this guide to create my own python packages: https://python-packaging.readthedocs.iao/en/latest/

对于所有软件包，最小结构为:

For all packages, the minimal structure is:

myOwnPackage/
    myOwnPackage/
        __init__.py
    setup.py

现在，我创建了一个依赖于其他自定义程序包的程序包.其结构为:

Now, I created a package wich depends on other custom packages. Its structure is:

myOwnPackage/
    dependencies/
        packageA
        packageB
    myOwnPackage/
        __init__.py
    setup.py

我的问题是:如何使用pip轻松安装myOwnPackage及其自定义依赖项?

My question is: How to easily install myOwnPackage and its custom dependencies with pip ?

对于上面的示例，当我像这样调用pip时，我想安装myOwnPackage，packageA和packageB:pip install myOwnPackage

For the above example, I would like to install myOwnPackage, packageA and packageB when I call pip like that: pip install myOwnPackage

我没有找到在setup.py中包含依赖项名称的方法，就像我可以对numpy，pyqt5等官方python软件包所做的那样.

I did not find a way to include dependency names in setup.py like I can do for offcial python packages like numpy, pyqt5 etc.

我找到了一种方法，通过在pip中使用requirements.txt来部分解决我的问题:

I find a way to solve my problem partially by using a requirements.txt with pip:

pip install -r requirements.txt myOwnPackage

这是我编写需求文件的方式:

and here is how I wrote the requirement file:

./dependencies/packageA
./dependencies/packageB

我工作得很好，但是当我有这样的递归依赖项时:

I works well, but not when I have recursive dependencies like that:

myOwnPackage/
    dependencies/
        packageA/
            dependencies/
                packageC
            packageA/
                __init__.py
            setup.py
            requirements.txt
        packageB
    myOwnPackage/
        __init__.py
    setup.py
    requirements.txt

具有最高要求的pip.txt将安装myOwnPackage，packageA和packageB，但它不知道必须安装是packageA依赖项的packageC.

pip with the top-level requirements.txt will install myOwnPackage, packageA and packageB but it does not know that it has to install packageC which is a packageA dependency.

有什么主意吗?

推荐答案

我几乎解决了我的问题.

I almost solved my problem.

我需要使用以下命令构建每个依赖项:python setup.py sdist为了创建单个程序包文件(tar.gz)

I need to build each dependency with the following command: python setup.py sdist in order to create a single package file (tar.gz)

然后，我可以在顶级程序包setup.py中调用它们:

Then, I can call them in the top-package setup.py:

...
dependency_links=["file:/local/path/myOwnPackage/dependencies/packageA/dist/packageA-0.1.tar.gz"],
install_requires=["packageA"],
...

最后，我运行以下命令来安装myOwnPackage及其本地依赖项:

Finaly, I run the following command to install myOwnPackage and its local dependencies:

pip install . --process-dependency-links

如果按照上述方法正确构建和设置了所有存储库，则它将安装所有递归依赖项.

It installs all recursive dependencies if all repo are built and set correctly as describe above.

--process-dependency-links在上一个版本的pip中已被删除...

--process-dependency-links has been removed in last version of pip...
