After upgrade from 6 -> 7

I've upgraded with below composer.json but when running php artisan optimize i get this:

PHP Warning: require(/var/www/myproject_dev2/myproject/vendor/composer/../../src/Illuminate/Foundation/helpers.php): failed to open stream: No such file or directory in /var/www/myproject_dev2/myproject/vendor/composer/autoload_real.php on line 41 PHP Fatal error: require(): Failed opening required '/var/www/myproject_dev2/myproject/vendor/composer/../../src/Illuminate/Foundation/helpers.php' (include_path='.:/usr/share/php') in /var/www/myproject_dev2/myproject/vendor/composer/autoload_real.php on line 41

Any idea ?

Composer.json
