Как решить эту проблему?

Answer 1

[Владислав]

"Unfortunately the latest release of Laravel does not support Symfony 3.1 components.

It looks like they are planning to support them in Laravel 5.3, but until that is released it won't be possible to installed stable versions of Laravel and Symfony 3.1 together"
