Switch between multiple versions of Python on Mac and python on mac

Switch between multiple versions of Python on Mac and python on mac

Python 2.x is installed on Mac. Sometimes Python 3.x is used for development, but Python 2.x cannot be deleted, which may cause system instability. Therefore, multiple versions of Python must be installed.

1. Install Python 3.x. I have installed Python 3.6.1;

2. Open the terminal and enter sudo vi ~ /. Bashrc;

3. On the top of the pop-up editing page, enter and save:

Alias python2 = '/Library/Frameworks/Python. framework/Versions/2.x/ bin/python2.x' alias python3 = '/Library/Frameworks/Python. framework/Versions/3.x/ bin/python3.x'

Python and Python 3.6 are available on our machine. Replace x with your own version based on your needs.

4. Restart the terminal (terminal) or enter: source ~ /. Bashrc

5. Verify that the input of python2 in the terminal indicates the version of Python2.x, and the input of python3 indicates the version of Python3.x.
