Mac OS X comes with Python 2.7 out of the box.
The steps to install pip3 are simple and easy to follow. Once you have python 3, use the following command to install pip3: sudo apt-get update sudo apt install python3-pip. Python3 get-pip.py. When you run this command, it installs the applications used to build python modules. Download Mac OS X 64-bit/32-bit x86-64/i386 Installer; Python 2.6.9 - Oct. No files for this release. Python 3.3.2 - May 15, 2013.
You do not need to install or configure anything else to use Python 2. Theseinstructions document the installation of Python 3.
The version of Python that ships with OS X is great for learning, but it’s notgood for development. The version shipped with OS X may be out of date from theofficial current Python release,which is considered the stable production version.
WARNING: for a modern macOS (2019) this can install python3, and for python2 you really need to do: brew install python@2. Install python3: brew install python3 UPDATE: Python 3. If you install python3, pip will be installed automatically. Brew install python3 NEW 2019: now to use pip version 3, use pip3, or you can execute: python3, to. $ mkvirtualenv cv342 -p python3 $ pip install opencv-contrib-python3.4.2 $ deactivate $ $ # next environment $ mkvirtualenv cv343 -p python3 $ pip install opencv-contrib-python3.4.3 Max Lee September 19, 2018 at 12:41 pm.
Doing it Right¶
Let’s install a real version of Python.
Before installing Python, you’ll need to install GCC. GCC can be obtainedby downloading Xcode, the smallerCommand Line Tools (must have anApple account) or the even smaller OSX-GCC-Installerpackage.
Note
If you already have Xcode installed, do not install OSX-GCC-Installer.In combination, the software can cause issues that are difficult todiagnose.

Note
If you perform a fresh install of Xcode, you will also need to add thecommandline tools by running
xcode-select--install
on the terminal.While OS X comes with a large number of Unix utilities, those familiar withLinux systems will notice one key component missing: a package manager.Homebrew fills this void.
To install Homebrew, open
Terminal
oryour favorite OS X terminal emulator and runThe script will explain what changes it will make and prompt you before theinstallation begins.Once you’ve installed Homebrew, insert the Homebrew directory at the topof your
PATH
environment variable. You can do this by adding the followingline at the bottom of your ~/.profile

Now, we can install Python 3:
This will take a minute or two.
Pip¶

At this point, you have the system Python 2.7 available, potentially theHomebrew version of Python 2 installed, and the Homebrewversion of Python 3 as well.

If the Homebrew version of Python 2 is installed then
pip2
will point to Python 2.If the Homebrew version of Python 3 is installed then pip
will point to Python 3.The rest of the guide will assume that

references Python 3.Pipenv & Virtual Environments¶
The next step is to install Pipenv, so you can install dependencies and manage virtual environments.
A Virtual Environment is a tool to keep the dependencies required by different projectsin separate places, by creating virtual Python environments for them. It solves the“Project X depends on version 1.x but, Project Y needs 4.x” dilemma, and keepsyour global site-packages directory clean and manageable.
For example, you can work on a project which requires Django 1.10 while alsomaintaining a project which requires Django 1.8.
