Install Brew On Osx
Homebrew users can just run “brew install postgis” and tends to be a favorite for more advanced users since there are brew scripts for most of the popular PostgreSQL extensions, not always present in other Mac distributions. The EnterpriseDb OSX PostgreSQL combination from EnterpriseDB includes generally latest stable minor version of PostGIS. Brew tap pothosware/homebrew-pothos brew update brew install limesuite. Windows only, OSX and Linux users do not need to install drivers for USB support. Then run the brew install octave command again. Note: If brew complains about not having a formula for octave, the following command should fix it: brew tap -repair. The command below upgrades Octave and its dependencies to the latest Homebrew-supported versions: brew update && brew upgrade octave. # Homebrew brew install gpatch brew install opam # MacPort port install opam. See also howto setup Emacs.app for Opam usage. Versions 18.04 and newer. There is a ppa available that contains the current stable version of opam. Add-apt-repository ppa:avsm/ppa apt update apt install opam Versions older than 18.04. Use the binary distribution. If you perform a fresh install of Xcode, you will also need to add the commandline tools by running xcode-select-install on the terminal. While OS X comes with a large number of Unix utilities, those familiar with Linux systems will notice one key component missing: a decent package manager.

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.
Install Brew On Osx Windows 10
Upgrade mac os lion to catalina. 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 The version shipped with OS X may be out of date from theofficial current Python release,which is considered the stable production version.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 runningxcode-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 run
The 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 file
Install Brew On Mac Mojave
Now, we can install Python 2.7: Upgrade from os x mountain lion to mojave.
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_installin 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.
For example, you can work on a project which requires Django 1.10 while alsomaintaining a project which requires Django 1.8.
