CocoaPods is built with Ruby and it will be installable with the default Ruby available on macOS. You can use a Ruby Version manager, however we recommend that you use the standard Ruby available on macOS unless you know what you're doing. Using the default Ruby install will require you to use sudo when installing gems. This will take about 30 minutes. We will be setting up a Ruby on Rails development environment on macOS 10.14 Mojave. Older versions of OS X are mostly compatible so follow along as far as you can and then Google search for any problems you run into.
Note
Check out our guide for installing Python 3 on OS X.
Install Ruby In Mac
Mac OS X comes with Python 2.7 out of the box.
You do not need to install or configure anything else to use Python. Having saidthat, I would strongly recommend that you install the tools and librariesdescribed in the next section before you start building Python applications forreal-world use. In particular, you should always install Setuptools, as it makesit much easier for you to install and manage other third-party Python libraries.
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 The version shipped with OS X may be out of date from theofficial current Python release,which is considered the stable production version.
Doing it Right¶
Let’s install a real version of Python.
Before installing Python, you’ll need to install a C compiler. The fastest wayis to install the Xcode Command Line Tools by running
xcode-select--install
. You can also download the full version ofXcode from the Mac App Store, or theminimal but unofficialOSX-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 decent 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
fileNow, we can install Python 2.7:
Because
python@2
is a “keg”, we need to update our PATH
again, to point at our new installation:Homebrew names the executable
python2
so that you can still run the system Python via the executable python
.Setuptools & Pip¶
Homebrew installs Setuptools and
pip
for you.Setuptools enables you to download and install any compliant Pythonsoftware over a network (usually the Internet) with a single command(
easy_install
). It also enables you to add this network installationcapability to your own Python software with very little work.pip
is a tool for easily installing and managing Python packages,that is recommended over easy_install
. It is superior to easy_install
in several ways,and is actively maintained.Virtual Environments¶
A Virtual Environment (commonly referred to as a ‘virtualenv’) 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.
Install Mac Os From Usb
For example, you can work on a project which requires Django 1.10 while alsomaintaining a project which requires Django 1.8.
To start using this and see more information: Virtual Environments docs.
