HOW TO BREW INSTALL OPENCV FFMPEG UPDATE
Now that Homebrew is successfully installed and updated, we need to update our ~/.bash_profile file so that it searches the Homebrew path for packages/libraries before it searches the system path.

I have included the command below as reference: $ ruby -e "$(curl -fsSL )"Īfter Homebrew installs you should make sure the package definitions (i.e., the instructions used to install a given library/package) are up to date by executing the following command: $ brew update Installing Homebrew is dead simple - simply copy and paste the command below the “Install Homebrew” section of the Homebrew website (make sure you copy and paste the entire command into your terminal). You can think of Homebrew as the macOS equivalent of the Ubuntu/Debian-based apt-get. We are now ready to install Homebrew, a package manager for macOS. If you haven’t already, be sure you have accepted the Xcode license using the following command: $ sudo xcodebuild -license The actual install process of Apple Command Line Tools should take less than a 5 minutes. Simply click the “Install” button to continue. When executing the above command you’ll see a confirmation window pop up asking you to approve the install: Figure 2: Installing Apple Command Line Tools on macOS. This is a required step, so make you install the Apple Command line tools via: $ sudo xcode-select -install These tools include packages such as make, GCC, clang, etc. Now that Xcode is installed and we have accepted the Apple developer license, we can install the Apple Command Line Tools. If you have already installed Xcode and previously accepted the Apple developer license, you can skip this step. Scroll to the bottom of the license and accept it. Just open up a terminal and execute the following command: $ sudo xcodebuild -license Personally, I think this is easier to do via the terminal. If so, you’ll need to accept the developer license before continuing.
I’m assuming that you’re working with a fresh install of macOS and Xcode. I would suggest installing Xocde in the background while you are getting some other work done or going for a nice long walk. Simply open up App Store, search for “Xcode” in the search bar, and then click the “Get” button: Figure 1: Downloading and installing Xcode on macOS.ĭepending on your internet connection and system speed, the download and install process can take anywhere from 30 to 60 minutes. The easiest method to download and install Xcode is to use the included App Store application on your macOS system.

macOS Sierra: Install OpenCV 3 and Python 3.5īefore we can install OpenCV 3 on macOS via Homebrew, we first need to install Xcode, a set of software development tools for the Mac Operating System.macOS Sierra: Install OpenCV 3 and Python 2.7.If you prefer to compile OpenCV from source with Python bindings on macOS, please refer to these tutorials: The benefit of using Homebrew is that it greatly simplifies the install process (although it can pose problems of its own if you aren’t careful) to only a few set of commands that need to be run.

The remainder of this blog post demonstrates how to install OpenCV 3 with both Python 2.7 and Python 3 bindings on macOS via Homebrew. Install OpenCV 3 on macOS with Homebrew (the easy way) To discover the easy way to install OpenCV 3 on macOS via Homebrew, just keep reading. You lose a bit of control (as compared to compiling from source), but what you gain is an easier to follow path to installing OpenCV on your Mac system. Well, there’s a little more to it than that… but the process is greatly simplified. So, is it really that easy? Just can a few simple keystrokes and commands can be used to avoid the hassle and install OpenCV 3 without the headaches?
It turns out, there is - just use Homebrew, what many consider to be “the missing package manager for Mac”. “Is there an easier way to install OpenCV on macOS? A way that avoids the complicated CMake configuration?” The downside is that determining the correct CMake paths to your Python interpreter, libraries, and include directories can be non-trivial, especially for users who are new to OpenCV/Unix systems. Over the past few weeks I have demonstrated how to compile OpenCV 3 on macOS with Python ( 2.7, 3.5) bindings from source.Ĭompiling OpenCV via source gives you complete and total control over which modules you want to build, how they are built, and where they are installed.Īll this control can come at a price though.
