I'm currently using Mac Pro and downloaded python through brew install python for the latest version (though it downloaded 3.9.12 instead of 3.10.x).

Also, while playing with the command lines, I also installed pyenv (version 2.2.5).

The problem is, I am now unable to get the default python version. The command python --version and python -h all gives me zsh: command not found: python.

However, when I do python3 --version, it gives me Python 3.9.12.

Did I mess things up? Is there are way to go back to the state before I altered anything? (or at least recover my default python version?)

  • `/usr/bin/python3`, you can use `whereis python3` to know it's location – sahasrara62 Apr 04 '22 at 04:45
  • II'm actually trying to look for the default python rather than python3.. Is there a way? The `whereis python` just gives me the result of `python:` – Learner_15 Apr 04 '22 at 04:52

  • hmm.. I'm not being able to get the specific answer I wish to get... Would this mean that I am unable to recover the default python of the macos? (which I remember is the python 2 version) – Learner_15 Apr 04 '22 at 05:08
  • Are you sure you have Python2 installed to begin with? I'm writing from a Mac pro as well, and I'm getting the same results as you are. – Carlo Apr 04 '22 at 06:19
  • really? I guess then this is normal? Cos when I started my python right after I bought Mac pro, I got the results that it had a default python of version 2.7.x. After installing python 3.x.x, the `python --version` disappeared and only the `python3 --version` is showing. – Learner_15 Apr 04 '22 at 14:02

  • I was recommended this page earlier, but it doesn't really answer my question... I'm currently actually guessing that either the default python version was deleted from the mac pro somehow while I was fidgeting around :( – Learner_15 Apr 06 '22 at 01:47

What version of MacOS are you running? Starting in 12.3, Python2 was removed from the system.

Python Deprecations Python 2.7 was removed from macOS in this update. Developers should use Python 3 or an alternative language instead. (39795874)
