ubuntu 22.04系统中报错：Python 3.6 is no longer supported by the Python core team...解决方式

今天我在ubuntu 22.04中执行一下：docker-compose --version命令报以下错误：

[email protected]:~# docker-compose --version
/snap/docker/2746/lib/python3.6/site-packages/paramiko/transport.py:32: CryptographyDeprecationWarning: Python 3.6 is no longer supported by the Python core team. Therefore, support for it is deprecated in cryptography. The next release of cryptography (40.0) will be the last to support Python 3.6.
  from cryptography.hazmat.backends import default_backend
docker-compose version 1.29.2, build unknown

/snap/docker/2746/lib/python3.6/site-packages/paramiko/transport.py:32: CryptographyDeprecationWarning: Python 3.6 is no longer supported by the Python core team. Therefore, support for it is deprecated in cryptography. The next release of cryptography (40.0) will be the last to support Python 3.6.

  from cryptography.hazmat.backends import default_backend

原因：

这是属于加密弃用警告：Python核心团队不再支持Python 3.6

我上网查了一下，有说降级，升级的

不过我用不到python其他的功能，只是一个docker-compose的依赖

解决思路：

docker-compose必须为2.X，之后您需要将旧命令引用到新命令

解决方式：

做一个别名，执行以下命令

alias docker-compose='docker compose'

就ok了

重新执行命令报错就没了
