Installing Python 2 on Mac OS X¶

Mac Bone X comes with Python 2.7 out of the box.

You lot practise not need to install or configure anything else to apply Python. Having said that, I would strongly recommend that y'all install the tools and libraries described in the next section before you offset building Python applications for existent-globe use. In particular, y'all should ever install Setuptools, as information technology makes it much easier for you to install and manage other tertiary-party Python libraries.

The version of Python that ships with Bone X is cracking for learning, but information technology's non practiced for development. The version shipped with OS 10 may be out of date from the official current Python release, which is considered the stable production version.

Doing information technology Correct¶

Let's install a real version of Python.

Before installing Python, y'all'll demand to install a C compiler. The fastest mode is to install the Xcode Control Line Tools by running xcode-select --install . You can besides download the full version of Xcode from the Mac App Store, or the minimal but unofficial OSX-GCC-Installer package.

Note

If yous already have Xcode installed, do not install OSX-GCC-Installer. In combination, the software tin can cause issues that are difficult to diagnose.

Note

If you perform a fresh install of Xcode, you will also need to add the commandline tools past running xcode-select --install on the terminal.

While OS X comes with a large number of Unix utilities, those familiar with Linux systems will find one key component missing: a decent bundle manager. Homebrew fills this void.

To install Homebrew, open Terminal or your favorite Bone 10 concluding emulator and run

                            $              /usr/bin/ruby -e              "              $(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/principal/install)              "

The script will explain what changes it will make and prompt yous before the installation begins. In one case yous've installed Homebrew, insert the Homebrew directory at the elevation of your PATH environment variable. You tin can practise this by calculation the post-obit line at the bottom of your ~/.profile file

                            export PATH="/usr/local/bin:/usr/local/sbin:$PATH"

Now, nosotros tin install Python 2.7:

Because python@2 is a "keg", we need to update our PATH again, to point at our new installation:

                            consign PATH="/usr/local/opt/python@2/libexec/bin:$PATH"

Homebrew names the executable python2 so that you can still run the system Python via the executable python .

                            $              python -V              # Homebrew installed Python 3 interpreter (if installed)              $              python2 -5              # Homebrew installed Python 2 interpreter              $              python3 -V              # Homebrew installed Python 3 interpreter (if installed)

Virtual Environments¶

A Virtual Environment (commonly referred to as a 'virtualenv') is a tool to keep the dependencies required by different projects in separate places, by creating virtual Python environments for them. Information technology solves the "Project X depends on version one.x but, Projection Y needs 4.ten" dilemma, and keeps your global site-packages directory clean and manageable.

For example, you can work on a projection which requires Django i.10 while too maintaining a project which requires Django ane.eight.
