Install PyQt on Mac

Installing Python 3 and PyQt5 on Mac OS X with Homebrew.

Homebrew is a package manager for OS X.
It allows to install and manage easily hundreds of “packages” or programs via the command lines.
This method has been tested on OS X Yosemite and works for all versions of OS X.
3 steps are required.

Step 1: installation of XCode

• Go to the App Store to download the latest free version of XCode.
  Once installed, open the Terminal (located in Applications/Utilities) and enter the following command line:
  xcode-select --install

• A pop-up should appear asking for confirmation to start the installation. Click Install and complete the installation.

Step 2: installation of Homebrew

• Enter the following command line in the Terminal:
  /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

• Note:
  the installation requests several times to validate command lines by pressing on the “Enter” key and even enter the password to run a sudo command.

• Once the installation is complete, run the “brew doctor” command, which is designed to detect if Homebrew is installed on your system:
  brew doctor

• Note:
  If you get the message /usr/bin occurs before /usr/local/bin, run the following command as recommended on the Homebrew website:
  echo 'export PATH="/usr/local/bin:$PATH"' >> ~/.bash_profile
  The purpose of this command is to move the Brew component to a location on the disk where it will be accessible globally on your computer.
  You can then run the Brew command from any path in the command line.

Step 3: installation of Python 3 and PyQt5

• Enter the following command lines in the Terminal:
  brew update
brew install python
pip3 install PyQt5 PyQtWebEngine
