  • What you were trying to do (and why) I am trying to install brew on clean macOS Catalina (10.15) using the following command: /usr/bin/ruby -e "$(curl -fsSL Skip to content.
  • How to install Homebrew on Mac What you need. Before you install Homebrew on Mac, you’ll need to make sure you have the following: A 64-bit Intel CPU or an Apple Silicon CPU (i.e., an M1 Mac) You can check if you have a compatible Mac by pressing cmd + spacebar, typing “About This Mac”, pressing return, and then checking the Processor.
  • Install PostgreSQL using Homebrew. In Terminal run the following command to install PostgreSQL on Mac using Homebrew. $ brew install postgres. We can check the version of PostgreSQL using the psql command. $ psql -version psql (PostgreSQL) 11.5.
  • So I'm running macOS 10.15.2 Catalina and try to install mariadb (10.4.11, the lastest version) with Homebrew. After running brew install mariadb, brew warned that the postinstalllation didn't complete successfully.

Mac users with macOS Mojave and macOS Catalina, and new operating systems in place can now install Command Line Tools from the Xcode IDE without needing to install the entire Xcode package, or opening an Apple developers account.

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 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 The version shipped with OS X may be out of date from theofficial current Python release,which is considered the stable production version.

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 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

If you have OS X 10.12 (Sierra) or older use this line instead

Now, we can install Python 3:

Brew Install Openssl Mac Catalina

This will take a minute or two.

Pip¶

Homebrew installs pip pointing to the Homebrew’d Python 3 for you.

Working with Python 3¶

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.

will launch the Homebrew-installed Python 3 interpreter.

will launch the Homebrew-installed Python 2 interpreter (if any).

Macos

will launch the Homebrew-installed Python 3 interpreter.

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 python 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. Rocket league on. 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.

So, onward! To the Pipenv & Virtual Environments docs!
