Right Way To Install Python On Mac

68

In this chapter, you learn how to install Python on MacOS, Windows, and Linux. We will look at multiple installation methods per platform and discuss what I think is the best option to choose from.

Most of the time, it’s not advisable to use the official installer from the python.org website. Instead, it’s better to go for the version packaged by your operating system. The advantage of OS supplied version, is that you’ll get automatic updates.

Install Python on Windows

There are three methods you can choose from on Windows.

Using The Microsoft Store

Microsoft hosts a community release of Python 3 in the Microsoft Store. This is the recommended way to install Python on Windows because it handles updates automatically and can be uninstalled easily too.

To use this method:

  • In this video we will learn how to setup your local dev environment for the Mac using Homebrew. We will install Git, Python3, pip and virtualenv.Links:Sign u.
  • The other way is install direct from python.org This will install a python into /usr/local/bin I think this installs a python and python3 executable. The issue with Homebrew is that it assumes that things in /usr/local are installed by it and so brew doctor will report these python.org pythons and libraries as issues and as this question shows.
  • What's written below is a helpful way to install Python (+ others) on a Mac if you are doing analytics/data science. FWIW, what is written by the OP is the 'right way' for non-data scientists. If you are using Python for analytics, I recommend using Anaconda (specifically Miniconda) for as much as you can, instead of Pip.
  • By the way, if you're wondering why I keep referring to Python 3.x – the x is a stand-in for sub-versions (or point releases as developers call them.) This means any version of Python 3. How to Install Homebrew on Mac. First you need to install Homebrew, a powerful package manager for Mac. Open up your terminal.

  • Pick the newest version and install it

With the official installer

You can download a Python installer from the official Python download website too. This method does not give you automatic updates, and I would recommend it only if you don’t have access to the Microsoft store.

Inside WSL

Right Way To Install Python On Mac

If you’re familiar with Windows Subsystem For Linux, you may want to consider that option too. It’s what I use myself, and I’m truly loving it. It offers me the advantages that Windows has to offer (mainly great hardware support), while still enjoying Linux which is, in my opinion, the best platform for Python development.

To install in WSL, you’ll first need to install WSL itself. Go for WSL2 if you can. It’s much better. After that, simply follow the Linux installation instructions below!

Installation on MacOS

On most versions of MacOS before Catalina, a distribution of Python is already included. Unfortunately, it’s almost certainly an old version, Python 2.7. Luckily, there are two ways to install Python 3 on a Mac with ease.

Homebrew

First and foremost, I recommend looking into Homebrew. It allows you to install almost anything easily. The added benefit is that it’s also easy to upgrade to newer versions later on.

Once you are up and running with homebrew, installing Python on MacOS is as easy as:

Alternatively, you can download an installer from the Python download website. The downside to this approach is that you won’t get automatic updates.

Install Python on Linux

There are several ways to install Python on Linux, that is, if you need to install it at all!

Check what’s installed first

Most Linux distributions include Python. Many will include both Python 2 and Python 3.

If you enter python --version on the command line, you’ll see the version number. It’s probably version 2.7:

You don’t want Python 2, but some OS’es still ship with it, unfortunately.

Now try python3 --version. If you get a “command not found,” you need to install Python 3. If your output looks similar to this, you’re in luck:

Using a package manager

Depending on the distribution of Linux you are running, you can install Python with the default package manager: Yum, APT, etcetera. You’ll need to find out for your specific Linux distribution which package manager is used and how to use it.

If you’re on Ubuntu, Linux Mint, or Debian, you can install using apt:

Homebrew

Another interesting option for Linux is using Homebrew. That’s right, the package manager for Macs also works on Linux.

The major advantages of using Homebrew:

  • You’ll get the latest version of Python, instead of the version your OS shipped with
  • You don’t need root access to your system. All the software installed with Homebrew is installed in your home directory

I find myself using Homebrew more and more while working under Linux — give it a try!

Python in your browser

If you don’t feel like installing Python, or you are unable to install it for whatever reason, I’ll offer an alternative too: you can use Python right from your browser; no installation necessary!
