pip install --process-dependency-links app.whl 不安装私有仓库（分叉库）答案

【问题标题】：pip install --process-dependency-links app.whl doesn't install private repo (forked library)pip install --process-dependency-links app.whl 不安装私有仓库（分叉库）

【问题描述】：

我有一个关于分发我使用 .whl（而不是 pypi）创建的应用程序的问题。我想要实现的是能够做到pip install --process-dependency-links my_app.whl。到目前为止，安装在新的 virtualenv 上按预期进行，除了我在 dependency_links 中定义的内容。我的setup.py 看起来像这样：

setup(
    ...
    install_requires=[
        'Click',
        'flask',
        ....,
        'vertica-python==0.7.3'
    ],
   dependency_links=[
        'https://github.com/lv10/vertica-python/tarball/master/#egg=vertica-python-0.7.3',
    ],
    ...
)

我关注了不同的tutorials 并查阅了几个stackoverflow 帖子：1、2、3、4。但是，无论我尝试什么--process-dependency-links 标志都不会触发查找dependency-links，而是安装过程会导致从pypi 安装vertica-python。

我运行pip install --process-dependency-links app.whl --verbose 看看在详细模式下是否有什么特别之处。这就是我得到的结果（确认显而易见）：

如果我使用pip install --process-dependency-links app.whl --find-links=https://github.com/lv10/vertica-python/tarball/master/master.tar.gz#egg=vertica-python-0.7.3，则安装分叉版本，这意味着setup.py 中的dependency_links 将被忽略。

在此先感谢，我将不胜感激朝着正确的方向前进。

【解决方案1】：

我怀疑 pip 是因为依赖链接没有以有效的包文件扩展名结尾的事实而被抛弃。将 URL 改为：

https://github.com/lv10/vertica-python/tarball/master/master.tar.gz#egg=vertica-python-0.7.3

【讨论】：

感谢您帮助我。在我再次尝试之前，我曾尝试使用...master/master.tar.gz#...，但无济于事。我会将 pip 中的--verbose 添加到问题中。
使用--find-links 标志和pip 确实安装了vertica_python，但我还有一些其他库要安装，所以我需要--process-dependency-links 才能工作。对于为什么这可能会失败，您还有其他建议吗？
