Python Installation on Mac

On Mac, use Homebrew to install Python 3, then use pipenv to manage individual project dependencies.

brew install python3

Add aliases to ~/.zshrc file:

alias python=python3
alias pip=pip3

Test that Python 3.x and pip are working:

python --version
pip --version

Check what packages are installed globally with pip:

pip list

Package    Version
---------- -------
pip        20.1.1
setuptools 49.2.0
wheel      0.34.2

Install pipenv, the per-project package manager:

pip install --user pipenv

which gave me a warning

WARNING: The scripts pipenv and pipenv-resolver are installed in '/Users/rr214/Library/Python/3.8/bin' which is not on PATH.

so I added the directory to my path:

export PATH=$PATH:/Users/rr214/Library/Python/3.8/bin

mkdir my-demo
cd my-demo
pipenv install requests

Now we have a pipenv with our first dependency, requests.

Create a little test script, main.py:

import requests

response = requests.get('https://httpbin.org/ip')

print('Your IP is {0}'.format(response.json()['origin']))

And run:

pipenv run python main.py
