Pip：连接因“ProtocolError”而中断

Question

我正在尝试在Ubuntu 20.04.5pip上的全新虚拟环境中安装软件包，但当我第二次运行时，我不断收到以下警告。第一次尝试后软件包安装失败。pip

\n

WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by \'ProtocolError(\'Connection aborted.\', FileNotFoundError(2, \'No such file or directory\'))\': /simple/pip/\nWARNING: Retrying (Retry(total=3, connect=None, read=None, redirect=None, status=None)) after connection broken by \'ProtocolError(\'Connection aborted.\', FileNotFoundError(2, \'No such file or directory\'))\': /simple/pip/\nWARNING: Retrying (Retry(total=2, connect=None, read=None, redirect=None, status=None)) after connection broken by \'ProtocolError(\'Connection aborted.\', FileNotFoundError(2, \'No such file or directory\'))\': /simple/pip/\nWARNING: Retrying (Retry(total=1, connect=None, read=None, redirect=None, status=None)) after connection broken by \'ProtocolError(\'Connection aborted.\', FileNotFoundError(2, \'No such file or directory\'))\': /simple/pip/\nWARNING: Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by \'ProtocolError(\'Connection aborted.\', FileNotFoundError(2, \'No such file or directory\'))\': /simple/pip/\nWARNING: There was an error checking the latest version of pip.\n\n

\n

在新鲜环境中的第一次尝试有效

\n

./venv/bin/pip install --upgrade pip\nCollecting pip\n  Using cached pip-22.2.2-py3-none-any.whl (2.0 MB)\nInstalling collected packages: pip\n  Attempting uninstall: pip\n    Found existing installation: pip 20.0.2\n    Uninstalling pip-20.0.2:\n      Successfully uninstalled pip-20.0.2\nSuccessfully installed pip-22.2.2\n

\n

但同一命令随后失败，并且我看到警告消息。

\n

./venv/bin/pip install --upgrade pip\nRequirement already satisfied: pip in ./venv/lib/python3.8/site-packages (22.2.2)\nWARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by \'ProtocolError(\'Connection aborted.\', FileNotFoundError(2, \'No such file or directory\'))\': /simple/pip/\nWARNING: Retrying (Retry(total=3, connect=None, read=None, redirect=None, status=None)) after connection broken by \'ProtocolError(\'Connection aborted.\', FileNotFoundError(2, \'No such file or directory\'))\': /simple/pip/\nWARNING: Retrying (Retry(total=2, connect=None, read=None, redirect=None, status=None)) after connection broken by \'ProtocolError(\'Connection aborted.\', FileNotFoundError(2, \'No such file or directory\'))\': /simple/pip/\nWARNING: Retrying (Retry(total=1, connect=None, read=None, redirect=None, status=None)) after connection broken by \'ProtocolError(\'Connection aborted.\', FileNotFoundError(2, \'No such file or directory\'))\': /simple/pip/\nWARNING: Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by \'ProtocolError(\'Connection aborted.\', FileNotFoundError(2, \'No such file or directory\'))\': /simple/pip/\nWARNING: There was an error checking the latest version of pip.\n

\n

我也无法安装其他软件包

\n

./venv/bin/pip install --upgrade numpy\nWARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by \'ProtocolError(\'Connection aborted.\', FileNotFoundError(2, \'No such file or directory\'))\': /simple/numpy/\nWARNING: Retrying (Retry(total=3, connect=None, read=None, redirect=None, status=None)) after connection broken by \'ProtocolError(\'Connection aborted.\', FileNotFoundError(2, \'No such file or directory\'))\': /simple/numpy/\nWARNING: Retrying (Retry(total=2, connect=None, read=None, redirect=None, status=None)) after connection broken by \'ProtocolError(\'Connection aborted.\', FileNotFoundError(2, \'No such file or directory\'))\': /simple/numpy/\nWARNING: Retrying (Retry(total=1, connect=None, read=None, redirect=None, status=None)) after connection broken by \'ProtocolError(\'Connection aborted.\', FileNotFoundError(2, \'No such file or directory\'))\': /simple/numpy/\nWARNING: Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by \'ProtocolError(\'Connection aborted.\', FileNotFoundError(2, \'No such file or directory\'))\': /simple/numpy/\nERROR: Could not find a version that satisfies the requirement numpy (from versions: none)\nERROR: No matching distribution found for numpy\nWARNING: There was an error checking the latest version of pip.\n

\n

重现步骤

\n

创建新环境：

\n

python3 -m venv venv\nsource ./venv/bin/activate\n

\n

检查我使用的 Python 版本

\n

./venv/bin/python --version\nPython 3.8.10\n\n

\n

和点

\n

\xe2\x9d\xaf ./venv/bin/pip --version\npip 20.0.2 from /home/$USER/projects/venv/lib/python3.8/site-packages/pip (python 3.8)\n

\n

我没有使用代理并且我的防火墙已禁用。

\n

\xe2\x9d\xaf echo "$http_proxy"\n\n\xe2\x9d\xaf echo "$https_proxy"\n\n\xe2\x9d\xaf sudo ufw status\nStatus: inactive\n\n

\n

我可以在同一台计算机上的 Docker 容器中运行相同的步骤，不会出现任何问题。\nMyopenssl.conf没有更改。\n这似乎与我的本地 Python 设置有关。\nMypip config list为空。\n没有配置文件

\n

pip config list -v\nFor variant \'global\', will try loading \'/etc/xdg/pip/pip.conf\'\nFor variant \'global\', will try loading \'/etc/pip.conf\'\nFor variant \'user\', will try loading \'/home/$USER/.pip/pip.conf\'\nFor variant \'user\', will try loading \'/home/$USER/.config/pip/pip.conf\'\nFor variant \'site\', will try loading \'/home/$USER/git/infrastructure-manual-tasks/cropster-csar/resize-login-images/venv/pip.conf\'\n

\n

我使用谷歌DNS

\n

Link 12 (ens4)\n      Current Scopes: DNS    \nDefaultRoute setting: yes    \n       LLMNR setting: yes    \nMulticastDNS setting: no     \n  DNSOverTLS setting: no     \n      DNSSEC setting: no     \n    DNSSEC supported: no     \n  Current DNS Server: 8.8.8.8\n         DNS Servers: 8.8.8.8\n                      8.8.4.4\n                      1.1.1.1\n          DNS Domain: ~.     \n

\n

我注意到，当我强制pip使用不强制执行的不同镜像时，我可以安装软件包HTTPS。所以这个问题似乎与相关SSL，但我找不到它的来源。

\n

这有效

\n

./venv/bin/pip install --upgrade -i http://pypi.douban.com/simple --trusted-host pypi.douban.com numpy\nLooking in indexes: http://pypi.douban.com/simple\nCollecting numpy\n  Downloading http://pypi.doubanio.com/packages/d6/e2/bed33bdbf513cd6d3fcb4377792ef1b8aad941da542a191e1e2a98c6621f/numpy-1.23.3-cp38-cp38-manylinux_2_17_x86_64.manylinux2014_x86_64.whl (17.1 MB)\n     \xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81\xe2\x94\x81 17.1/17.1 MB 6.4 MB/s eta 0:00:00\nInstalling collected packages: numpy\nSuccessfully installed numpy-1.23.3\n

\n

但这在使用时不会HTTPS。

\n

\n

我不知道还能去哪里寻找。

\n

更新

\n

使用卷曲测试

\n

使用 访问存储库curl似乎没问题。

\n

Answer 1

我遇到了同样的问题。结果我通过将环境变量 SSLKEYLOGFILE 设置为后来删除的文件进行了一些调试，如果 pip 无法访问或创建该文件，则 pip 将无法工作。

删除环境变量即可修复
