I decided to learn symfony, so I tried installing it. After getting the composer, as the website says, I ran the following command to create the project and get symfony2
composer create-project symfony / framework-standard-edition Website / test
and unfortunately I received this as a message:
> Installing symfony / framework-standard-edition (v2.7.1)
- Installing symfony / framework-standard-edition (v2.7.1)

and I got PHP version 5.5.9 and ubuntu 14.04 as OS.
Can someone explain to me why I get these errors and how to solve them?
