I opted for CakePHP version 3 for a new project I am working on. Before starting the project I thought I would play around with the framework a bit. I chose Composer as the installation method. I ran the following command build a project called ctest.
composer create-project --prefer-dist cakephp/app ctest
I recieved the following errors and feedback.

You can also run \`php --ini\` inside terminal to see which files are used by PHP in CLI mode.
I resolved all of these by installing one extension; intl (Internationalization Functions).
sudo apt-get install php-intl
Once php-intl has been installed I removed the the ctest directory and reinstalled with the following feedback.
sudo rm -fR ctest
composer create-project --prefer-dist cakephp/app ctest
