This allows for easy upgrades, and still includes the ability to have MySQL start on boot. As a result, we now recommend installing and maintaining MySQL using Homebrew. Over the years, it has become difficult to ensure that the script works on all of the versions of macOS still in use, and support from MySQL for macOS is slow. So if you don’t have Python 3 installed, Homebrew will install it while installing opencv.In the past, we maintained a script for automating the installation of MySQL on macOS. Homebrew has also made it compulsory to compile and install Python bindings for both Python 2 and Python 3. Various options such as –with-qt, –with-tbb etc are also removed in the updated formula and CUDA support is also dropped. They have now renamed opencv3 to opencv and opencv to

Install python3 at /usr/local/bin/python3.

Install python2 at /usr/local/bin/python2.

Earlier homebrew used to install python2 as /usr/local/bin/python. NOTE : Recently Homebrew made some changes in Python formula. Python version (2.6 or 2.7, 3.5 or 3.6) installed on your machine is required to determine path of Python’s site-packages. Which python3 # it should output /usr/local/bin/python3 Which python2 # it should output /usr/local/bin/python2 # Check whether Python using homebrew install correctly

# Upgrade the python using new homebrew formulae. # NOTE : If you have python already installed using homebrew, # else skip the 3 lines below and upgrade. # If installing python for the first time using Homebrew,
