  To enable extensions, verify that they are enabled in those .ini files:
    - /etc/php5/cli/php.ini
    - /etc/php5/cli/conf.d/05-opcache.ini
    - /etc/php5/cli/conf.d/10-mysqlnd.ini
    - /etc/php5/cli/conf.d/10-pdo.ini
    - /etc/php5/cli/conf.d/20-curl.ini
    - /etc/php5/cli/conf.d/20-gd.ini
    - /etc/php5/cli/conf.d/20-json.ini
    - /etc/php5/cli/conf.d/20-mcrypt.ini
    - /etc/php5/cli/conf.d/20-mongo.ini
    - /etc/php5/cli/conf.d/20-mysql.ini
    - /etc/php5/cli/conf.d/20-mysqli.ini
    - /etc/php5/cli/conf.d/20-pdo_mysql.ini
    - /etc/php5/cli/conf.d/20-pdo_pgsql.ini
    - /etc/php5/cli/conf.d/20-pgsql.ini
    - /etc/php5/cli/conf.d/20-readline.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

Installation failed, reverting ./composer.json to its original content.
