pip install 生成警告： 'NewConnectionError('<pip._vendor.urllib3.connection.HTTPConnection object at ...>

Question

我花了很多时间搜索是否有人已经遇到了同样的问题，但我没有找到任何东西。

一段时间以来，每次我想用 pip 安装软件包时都会收到警告。安装最终成功，但需要更多时间。该警告包含重复 5 次相同的 WARNING ：

WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<pip._vendor.urllib3.connection.HTTPConnection object at 0x105b71c50>: Failed to establish a new connection: [Errno 61] Connection refused')': /simple/mako/
WARNING: Retrying (Retry(total=3, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<pip._vendor.urllib3.connection.HTTPConnection object at 0x105b6c690>: Failed to establish a new connection: [Errno 61] Connection refused')': /simple/mako/

在这些警告之后，一切似乎都运行良好，但我想删除它们以加快安装速度。

如果您需要更多信息，请随时询问，我不确定应该在哪里挖掘来解决这个问题，所以我不知道需要什么样的信息。

非常感谢您的帮助 ！

sudo apt-get upgrade
sudo apt install python3-pip
