我最近尝试使用 pip 安装软件包，当我输入 pip install... 命令并按回车键时，什么也没发生，该过程似乎停止了或在循环运行。没有输入，我关闭了终端。
与此同时，我更新了 python。我怀疑我可能做错了什么，但作为终端新手，我不确定可能出了什么问题。
我想我应该尝试重新安装 pip，但返回了下面给出的错误。
知道该去哪里调查吗？

还有另一种简单的方法，即使用 Curl 和 python 安装 pip。
sudo apt-get update
curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py"
python get-pip.py
现在验证 pip 安装：在终端上写入 pip。你可以看到一些代码。
如果你想检查版本
pip -V
