Ubuntu 20.04 问题：/usr/bin/python3: No module named pip

主要问题为/usr/local/lib/python3.8/dist-packages下没有get-pip.py这个文件
1、
先改权限 sudo chmod 777 /usr/local/lib/python3.8/dist-packages
ps:你输啥命令他提示你permission denied 的时候你就加一个sudo在前面,或者看看权限有没有
2、
cd /usr/local/lib/python3.8/dist-packages
3、
直接wget http://bootstrap.pypa.io/get-pip.py
可以查看一下/usr/local/lib/python3.8/dist-packages里有没有get-pip.py

4.运行文件

lee@lee-virtual-machine:/usr/local/lib/python3.10/dist-packages$ sudo python3 get-pip.py
