Answer 1

I got the same problem while upgrading an app from zf2 to zf3.
I solved the problem by loading the module Zend\Router. There are some more modules coming with ZF3, so I ended up using this in the modules.config.php:
return [
'Zend\Cache',
'Zend\Form',
'Zend\Hydrator',
'Zend\InputFilter',
'Zend\Paginator',
'Zend\I18n',
'Zend\Filter',
'Zend\Router',
'Zend\Validator',
'Zend\Navigation',
...
];
I got the modules.config.php and the new application.config.php from the zf3 skeleton application.
