CentOS7.6升级Python到3.9.5后使用pip时出现问题

Question

看大佬https://blog.csdn.net/longzhoufeng/article/details/109879818这个帖子的时候，按着教程来，安装好了以后，输入pip就会出现这个错误

[root@ecs-kc1-large-2-linux-20210423092937 ~]# pip
Traceback (most recent call last):
  File "/usr/bin/pip", line 9, in <module>
    load_entry_point('pip==21.1.1', 'console_scripts', 'pip')()
  File "build/bdist.linux-aarch64/egg/pkg_resources/__init__.py", line 547, in load_entry_point
  File "build/bdist.linux-aarch64/egg/pkg_resources/__init__.py", line 2719, in load_entry_point
  File "build/bdist.linux-aarch64/egg/pkg_resources/__init__.py", line 2379, in load
  File "build/bdist.linux-aarch64/egg/pkg_resources/__init__.py", line 2385, in resolve
  File "/usr/lib/python2.7/site-packages/pip/__init__.py", line 1, in <module>
    from typing import List, Optional
ImportError: No module named typing

有没有人救救我啊？

这个代码给参考

[root@ecs-kc1-large-2-linux-20210423092937 bin]# ll python*
