Trying on the new Sage Theme
Had to install Yarn (brew install yarn). Already had composer installed. Needed to upgrade my local version of php: https://coolestguidesontheplanet.com/upgrade-php-on-osx/ curl -s http://php-osx.liip.ch/install.sh | bash -s 7.0 Then point to it for php-cli: Add export PATH=/usr/local/php5/bin:$PATH to .bashrc, then source ~/.bashrc, which is the file named .bashrc in my home directory. Confirm with php –version.
