使用 setuptools 从 VCS 存储库子目录安装依赖项

Question

我正在尝试使用 setuptools 从 VCS 和子目录内安装依赖项。

我的setup.py看起来像这样：

#!/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 中运行时python3 setup.py install，出现以下错误：

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，我使用了以下公共 Github 存储库：

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

此处建议此示例作为类似问题的解决方案。我遇到了同样的unknown url type错误（该包最终是通过 PyPI 检索的，而不是通过 VCS URL 检索的！）。

我尝试过的

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： 好的

我也尝试删除git+所有这些 URL 的 ，但它cannot detect archive format.

我正在使用的版本

• 安装工具 46.4.0
• 蟒蛇3.6.9
• 点 20.1.1

dependency_links被宣布过时并最终在19.0中删除。pip它的替换是install_requires使用特殊语法（从 19.1 开始支持pip）：

install_requires=[
    'package_name @ git+https://gitlab.com/<PRIVATE_ORG>/<PRIVATE_REPO>.git@<COMMIT_ID>'
]

请参阅https://pip.readthedocs.io/en/stable/reference/pip_install/#requirement-specifiers和https://www.python.org/dev/peps/pep-0440/#direct-references

这需要pip install包含pip install .并且不适用于python setup.py install.

在你的情况下：

install_requires=[
    "package @ git+ssh://git@host/repo.git@tag#subdirectory=subdir"
]

setup(install_requires=install_requires)

例如：

install_requires=[
    pycocotools @ git+https://github.com/cocodataset/cocoapi.git#subdirectory=PythonAPI
]
