我尝试在 CentOS 7 Home Server 上运行 Debian 11 VM，但在 virt-install 中遇到了此问题

请参阅下文，我在尝试单独运行 virt-install 时遇到的问题。当我尝试使用我计划使用的所有配置时，出现同样的问题：

/usr/lib/python2.7/site-packages/requests/__init__.py:104: RequestsDependencyWarning: urllib3 (1.26.9) or chardet (2.2.1)/charset_normalizer (None) doesn't match a supported version!

    def where() -> str:
                ^

我还看到突出显示的主要问题/usr/lib/python2.7/site-packages/requests/__init__.py:104: RequestsDependencyWarning: urllib3 (1.26.9) or chardet (2.2.1)/charset_normalizer (None) doesn't match a supported version!

搜索后，我看到一个链接：https://stackoverflow.com/questions/50202238/python-pip-requestsdependencywarning-urllib3-1-9-1-or-chardet-2-3-0-doe

遵循此操作也不起作用，因为 pip 似乎不想工作：

pip install --upgrade urllib

  File "/bin/pip", line 9, in <module>
    load_entry_point('pip==8.1.2', 'console_scripts', 'pip')()

我完全陷入困境，不知道如何进步。

我的主要目标是运行这个软件 -https://github.com/ab77/netflix-proxy尽管我只搭建了一台 CentOS 7 服务器，而且我不打算用 Debian 重新安装机器，除非有人有更好的解决方案，否则我还是打算继续模拟。

嗨，我今天也遇到了同样的问题。我的解决方案是删除该目录/usr/lib/python2.7/site-packages/certifi。后来我用pip安装了2020.4.5.1版本 pip install certifi==2020.4.5.1

答案2

这个问题很新，我发现这是由Tornado引起的，在tornado-4.4.2.tar.gz里面，我发现这个文档说： Tornado 现在依赖于certifi <https://pypi.python.org/pypi/certifi>_ 包，而不是捆绑它自己的 Mozilla CA 列表副本。当使用pip或 时，这将自动安装easy_install。

并前往https://pypi.python.org/pypi/certifi，它显示的是最新版本：证书 2022.5.18.1 我正在使用docker，所以在我的Dockerfile中，安装Tornado后，我使用了cordiliere的建议（谢谢），

运行 rm -r /usr/lib/python2.7/site-packages/certifi

运行 pip install certifi==2020.4.5.1

它对我有用。

希望这会在下一个证书中得到解决
