Python 3.8.5 安装在 MacOS 上，但 python --version 返回 2.7.16 -- 我该如何解决这个问题？

Question

The following is what I see in my terminal (MacOS). I've installed python and it tells me that 3.8.5 is already installed, but when I ask the terminal what version I have, it gives me something different. How do I fix this? Or what am I doing wrong?

Warning: python@3.8 3.8.5 is already installed and up-to-date
To reinstall 3.8.5, run `brew reinstall python@3.8`
user ~ % python --version   
Python 2.7.16

Try using python3 --version . It will return the answer you are expecting.
