以前，我们仅将内部 pip 存储库用于源分发。展望未来，我们还希望托管轮子以完成两件事：
- 为（本地）开发人员机器和 Alpine Docker 环境提供我们自己的代码
- 为没有 Alpine 轮子的包裹创建轮子
不幸的是，使用不同库构建的轮子共享相同的工件名称，第二个被 pip 存储库拒绝：

设置和执行

git clone https://github.com/cython/cython cython-debian
docker-compose build
docker-compose up
最后，我希望两个测试容器都能够执行cython --version. 适用于 Alpine 容器：
alpine-test_1 | Collecting cython
alpine-test_1 | Downloading http://pypi:8080/api/package/cython/Cython-0.29.12-cp36-cp36m-linux_x86_64.whl (5.0MB)
alpine-test_1 | Installing collected packages: cython
alpine-test_1 | Successfully installed cython-0.29.12
alpine-test_1 | Cython version 0.29.12
但不适用于 Debian 容器：
debian-test_1 | Downloading http://pypi:8080/api/package/cython/Cython-0.29.12-cp36-cp36m-linux_x86_64.whl (5.0MB)
debian-test_1 | Installing collected packages: cython
debian-test_1 | Successfully installed cython-0.29.12
debian-test_1 | Traceback (most recent call last):

debian-test_1 | ImportError: libc.musl-x86_64.so.1: cannot open shared object file: No such file or directory
我发现这两种环境都试图拉动这个轮子特别奇怪，因为有各种各样的包不适用于 Alpine（例如 Pandas），在这种情况下 pip 直接用于源代码分发。我想我在这方面也一定做错了什么。
所以现在我想知道如何创建这些轮子，以便对于软件包的每个版本，两个不同的轮子可以存在于 pip 存储库中，并让 pip 自动下载并安装正确的轮子。
