原因：误删了centos8环境自带python3.6，重新拷贝以下文件即可

(因为我是用的centos镜像，所以直接拉取一遍镜像先拷贝到宿主机，再拷贝到发生问题的容器即可)。

发生问题时的whereis python

#> whereis python  
python: /usr/bin/python /usr/bin/python3.8 /usr/lib/python3.8 /usr/lib64/python3.8 /usr/local/lib/python3.8 /usr/include/python3.8 /usr/share/man/man1/python.1.gz

问题解决后时的whereis python

#> whereis python
python: /usr/bin/python /usr/bin/python3.8 /usr/lib/python3.6 /usr/lib/python3.8 /usr/lib64/python3.6 /usr/lib64/python3.8 /usr/local/lib/python3.8 /usr/include/python3.6m /usr/include/python3.8 /usr/share/man/man1/python.1.gz
