为什么 pip 无法在 ubuntu 20.04 lts 上干净升级？

pip upgrade 不起作用，显示已升级版本仍然显示旧版本

这是 python/pip 的位置

root@ubuntu:~# which pip
/usr/local/bin/pip
root@ubuntu:~# which pip3
/usr/local/bin/pip3
root@ubuntu:~# which python
/usr/bin/python
root@ubuntu:~# which python3

root@ubuntu:~# pip -V
pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.8)

我将把 pip 干净地指向 pip3，就像我之前做的那样apt install python-is-python3

有没有类似的包裹apt install pip-is-pip3？

我试图避免自己手动创建符号链接

目前基本上就是这样，但如果有人找到类似的非手动方法，apt install python-is-python3请发帖

root@ubuntu:~# rm -rf /usr/local/bin/pip
root@ubuntu:~# ln -s /usr/local/bin/pip3 /usr/local/bin/pip

root@ubuntu:~# rm -rf /usr/lib/python3/dist-packages/pip
root@ubuntu:~# ln -s /usr/local/lib/python3.8/dist-packages/pip /usr/lib/python3/dist-packages/pip

root@ubuntu:~# pip -V
pip 22.0.3 from /usr/lib/python3/dist-packages/pip (python 3.8)
