A new Laravel project produces "SessionHandlerInterface not found"

Question

I created a new Laravel 5.2 project and got stuck with the error:

local.ERROR: Symfony\Component\Debug\Exception\FatalErrorException: Interface 'SessionHandlerInterface' not found in /pathto/theproject/vendor/laravel/framework/src/Illuminate/Session/FileSessionHandler.php:10

It is running on a freebsd-10.3 server with ngingx-1.10 and PHP 7.

The .env file contains:

APP_ENV=local
APP_DEBUG=true
APP_KEY=secret-key
APP_URL=http://localhost

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=secret-dbname
DB_USERNAME=secret-uname
DB_PASSWORD=secret

CACHE_DRIVER=file
SESSION_DRIVER=file
QUEUE_DRIVER=sync

REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379

MAIL_DRIVER=sendmail

All other files are untouched. What did I wrong?

PS: a new project with Laravel 5.1.33 works.
