By default High Sierra and Mojave are coming with Python 3.7 now. It is extremely important to use Python 3.6. We’ll also install prerequisites for building OpenCV from source. In this section we’ll ensure that Python 3.6 is installed. Step #3: Install OpenCV prerequisites using Homebrew Once you’re back in bash, source your bash profile: $ source ~/.bash_profile

If you’re using nano, you’ll see the shortcut keys at the bottom of the window which demonstrate how to save (write) and exit.

Once you’re actively editing the file, append the following lines to the end to update your PATH : # Homebrewįrom there, save the profile. If you’re more comfortable with vim or emacs, then go for it.Įdit your bash profile with nano using the following command: $ nano ~/.bash_profile For simplicity, I suggest the nano text editor. This script is run each time you launch a terminal. Let’s update the Homebrew definitions: $ brew updateĪnd now let’s edit our Mac’s bash profile. When you’re ready, copy the entire command below to install Homebrew: $ /usr/bin/ruby -e "$(curl -fsSL )" Homebrew runs on Ruby which is a popular programming language. Step #2: Install Homebrewįor this step we’re going to install the Mac community package manager, Homebrew. You can install the tools via: $ sudo xcode-select -installįigure 2: Installing Apple Command Line Tools on macOS.Ĭlick the “Install” button and wait about 5 minutes for the installation to complete. This is required, so that you’ll have make, gcc, clang, etc. Once you’ve accepted the license agreement, let’s install Apple Command Line Tools. To accept the license, simply scroll down and accept it. Launch a terminal and enter the following command: $ sudo xcodebuild -license To install Xcode, launch the App Store, find Xcode, and run the installation.Īfter Xcode has installed we need to accept a license agreement. You’ll need to wait patiently as this figure indicates: Figure 1: Xcode is a dependency for Homebrew and therefore OpenCV 4 on macOS. To install Xcode, fire up the Apple App Store, find the Xcode app, and install. I’ll cover alternative methods (pip and Homebrew) in future installation guides (neither of these methods can be covered until OpenCV 4 is officially released).įinally, we’ll test out our OpenCV 4 install and get our feet wet with a real OpenCV project.

Compiling from source allows us to have full control over the compile and build as well as to install the full OpenCV 4 build. I post links to all my OpenCV install tutorials there.įirst, we’ll install Xcode and set up Homebrew.įrom there, we’ll establish Python virtual environments. Note: If you landed on the wrong install tutorial (perhaps you want to install OpenCV on Ubuntu or your Raspberry Pi), then you should visit my OpenCV installation guides page. OpenCV 4 is packed with new features, many of which are deep-learning focused. In this blog post we’re going to install OpenCV 4 on macOS. Looking for the source code to this post?
