Brew Install Python 3.8

3.8

Installing Python 3, with or without Homebrew, and using alias will let you start coding, but it's not a good strategy for the long run. Using pyenv as a simple version management solution to get you off to a good start. See Python for Formula Authors for advice on writing formulae to install packages written in Python. Homebrew should work with any CPython and defaults to the macOS system Python. Homebrew provides formulae to brew Python 3.x. Homebrew provided a [email protected] formula until the end of 2019, at which point it was removed due to the Python 2. For brewed Python, modules installed with pip3 or python3 setup.py install will be installed to the $(brew -prefix)/lib/pythonX.Y/site-packages directory (explained above). Executable Python scripts will be in $(brew -prefix)/bin. Apr 05, 2021 Open up your terminal. You can do this by using MacOS spotlight (command+space) and typing 'terminal'. Now that you're in a command line, you can install the latest version of Homebrew by running this command: /bin/bash -c '$ (curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)'. Jun 30, 2020 After a couple of failed attempts, I finally found the best way to install Python 3.8.0+ on my computer and make Python 3.8.3 the global version of Python. I ended up installing pyenv, the Python version manager, on my computer using Homebrew, and then configuringthe correct path to Python 3.8.3 in my.zshrc file located in my home directory.
