Exception during adding superuser

[fhamborg]

Following the guide, I get the following error message.

ubuntu@vm1:~/literaturemgmt/SciBib$ bin/cake users addSuperuser
PHP Warning:  Module 'intl' already loaded in Unknown on line 0
Exception: Database driver Cake\Database\Driver\Mysql cannot be used due to a missing PHP extension or unmet dependency in [/home/ubuntu/literaturemgmt/SciBib/vendor/cakephp/cakephp/src/Database/Connection.php, line 170]

Hey,

this error occurs if a PHP extension is missing.

Please install the PHP module for MySQL connections and restart apache.

sudo apt-get install php-mysql

sudo service apache2 restart

That solves the problem, thanks!
