Latest versionReleased:
Manage different versions of homebrew packages
Project description
Manage multiple versions of your Homebrew packages with ease!Homebrew makes this difficult as a design decision, but sometimes old packagesneed to be installed and we need a way to do so easily.
Installation
Homebrew Install Python 3.8
With pipx
Or just with pip:
Usage
Switch to a specific version:
Installing from taps:
When no bottle is found for taps it will proceed with searching thelocal tap repository for the correct version and installing from the bottledefined in the formula if it exists, otherwise from source.
This is very slow for the main homebrew repository so this behaviour is disabledwhen a bottle for a homebrew-core package cannot be found. You can supplythe option brewv switch --slow ... to perform this search.
Warnings
Proper SHA256 verification is not done when downloading bottles from themain bottle repository. This is because to get the expected SHAs would mean searchingthe huge homebrew-core repository.
While homebrew bottles exist for most operatingsystems, if the bottle is not found then parsing old formulas fails quite oftensince Homebrew updates their code frequently.

tldr; install brew; brew install python
Homebrew is a great installer for Mac and its main job is to make it easier to install packages.
Step 1: Download Homebrew here
'brew' hosts its package information here as “formulae“.
Step 2: Use brew to install the latest version of Python
$ brew install python --verbose
Brew Python 3.6
Now you can run python3 in your terminal
> python3
More details: So what happens when I run brew install?
When you run the command, brew will look for the package in the “formulae” list and run the installation script for the package.
Brew installs *all* packages into its own directory on your computer at /usr/local/Cellar .
Take a look with $ ls /usr/local/Cellar.
Brew Python3-dev
After installation, brew creates a symlink which is basically a shortcut that will allow your system to run the new command > python3.
