忽略pkg_resources.ContextualVersionConflict或ResolutionImpossible

Question

我构建了一个 python 模块，它安装 kwikapi==0.4.5 和 requests==2.22.0。但是 kwikapi 有 requests==2.18.4.

现在，当我安装并运行我的包时，我收到错误

pkg_resources.ContextualVersionConflict: (requests 2.22.0 (/tmp/test_vir3.7/lib/python3.7/site-packages), Requirement.parse('requests==2.18.4'), {'kwikapi'})

。

现在，如果我安装 requests==2.18.4(pip install requests==2.18.4) 并运行，则错误为

pkg_resources.DistributionNotFound: The 'requests==2.22.0' distribution was not found and is required by my-pack

。

我可以使用 2.18.4 而不是 2.22.0 请求来解决这个问题。但是如果我在两个请求和 kwikapi 中都有不同版本的相同模块，这个问题就会再次出现。

有办法忽略/解决这个错误吗？

您是否考虑过做类似的事情：

from setuptools import setup, find_packages

version = "0.0.1"
setup(
    name="my_pack",
    packages=find_packages("."),
    package_dir={"my_pack": "my_pack"},
    include_package_data=True,
    install_requires=[
        "kwikapi==0.4.5",
        "requests>=2.18.4,<3"  # Adjusted
    ],
    entry_points={"console_scripts": ["my_pack = my_pack:main"]},
)
