问使用setuptools从VCS repo子目录安装依赖项

EN

我正在尝试使用setuptools从VCS和子目录中安装一个依赖项。

我的setup.py看起来是这样的：

#!/usr/bin/env python3

from setuptools import setup

required = [
    "package"
]
dependency_links = [
    "git+ssh://git@host/repo.git@tag#subdirectory=subdir#egg=package-version"
]

setup(install_requires=required, dependency_links=dependency_links)

在virtualenv中运行python3 setup.py install，将得到以下错误：

Download error on git+ssh://git@host/repo.git@tag#subdirectory=subdir#egg=package-version: unknown url type: git+ssh -- Some packages may not be found!

为了调试起见，我使用了以下公共Github：

required = [
    "pycocotools"
]
dependency_links = [
    "git+https://github.com/cocodataset/cocoapi.git#subdirectory=PythonAPI#egg=pycocotools-2.0"
]

该示例建议使用这里作为类似问题的解决方案。我得到了相同的unknown url type错误(包最终是通过PyPI检索的，而不是通过VCS !)。

我试过的

git+https://github.com/cocodataset/cocoapi.git#subdirectory=PythonAPI#egg=pycocotools-2.0

• python3 setup.py install：unknown url type: git+https -- Some packages may not be found!
• pip3 install：ERROR: Could not install packages due to an EnvironmentError: [Errno 2] No such file or directory: '/tmp/pip-install-lwpbj7yv/pycocotools-2.0/PythonAPI#egg=pycocotools-2.0': '/tmp/pip-install-lwpbj7yv/pycocotools-2.0/PythonAPI#egg=pycocotools-2.0'

git+https://github.com/cocodataset/cocoapi.git#subdirectory=PythonAPI&egg=pycocotools-2.0

• python3 setup.py install：unknown url type: git+https -- Some packages may not be found!
• pip3 install：好的，但是WARNING: Generating metadata for package pycocotools-2.0 produced metadata for project name pycocotools. Fix your #egg=pycocotools-2.0 fragments.

git+https://github.com/cocodataset/cocoapi.git#subdirectory=PythonAPI&egg=pycocotools

• python3 setup.py install：unknown url type: git+https -- Some packages may not be found!
• pip3 install：OK

我也尝试为所有这些URL删除git+，但它是cannot detect archive format。

我正在使用的版本

• setuptools 46.4.0
• python 3.6.9
• pip 20.1.1
