Now install some python using pyenv and then switch to it with the pyenv local command (you can see all your versions with pyenv versions). This is how we’ve completely uninstalled Office 2011 and all corresponding files from Mac. If command -v pyenv 1>/dev/null 2>&1 then

The pyenv repo is pretty detailed on how to install for different systems and what it's actually doing, but here's the basic steps for mac:

Modify your shell environment ( PATH) with shims so that when you do pyenv local 3.8.1, calling python will invoke the new interpreter instead of your system python.

Doing pyenv install 3.8.1 will install python 3.8.1 under ~/.pyenv/versions/3.8.1.

Install different python versions under some directory.

Essentially, pyenv can do two key things for you: In this tutorial, you have learned how to create a list of alternate Python versions for update-alternatives and set the default.I recommend using pyenv to manage your local python versions (both 2.x and 3.x) instead of installing new versions directly with homebrew or building new python versions from source manually. Now check the default Python version has changed: Type the number of the version you wish to set as the default and press ENTER. Sudo update-alternatives -config python There are 3 choices for the alternative python (providing /usr/bin/python). Now you can change the default version of Python using the following command: Note - the number at the end of each command is the priority number. Update-alternatives: using /usr/bin/python2.7 to provide /usr/bin/python (python) in auto mode Update-alternatives: using /usr/bin/python3.9 to provide /usr/bin/python (python) in auto mode

Sudo update-alternatives -install /usr/bin/python python /usr/bin/python3.6 1 sudo update-alternatives -install /usr/bin/python python /usr/bin/python3.9 2 sudo update-alternatives -install /usr/bin/python python /usr/bin/python2.7 3 update-alternatives: using /usr/bin/python3.6 to provide /usr/bin/python (python) in auto mode Now run the following commands changing the version numbers to suit what you have. You may also want to list Python 2.* versions if you want to add one of them as an option:

Start by listing all the installed versions of Python 3 so you can choose the version options to add. To update Python to the latest version installed on your system, we can use update-alternatives to change the python shortcut command to point to Python 3.9.īefore we do this, we need to add Python 3.9 as an option in update-alternatives. If you have followed my article on how to install Python 3.9 on Ubuntu, you will notice that 3.9 is not the version used when running the following command: In this article, we will learn how to change the default Python version so that it can be used without explicitly typing a version number. After installing the latest version of Python 3 on your system, you will notice that an older version is still used when executing Python VIA the python and python3 commands.
