Run the following command to do it: $ source ~/.profile We need to reload the file to update the environment variables. Open up your ~/.profile file and add the following line: export PATH=/usr/local/bin:$PATH Now that Homebrew is installed, let’s update it and install Python: $ brew update If you don’t have Homebrew, you can install it using the following command: $ ruby - e "$(curl -fsSL Instead of using system Python, we need to use brewed Python (this is basically Python installed using Homebrew).
