Erro autoload_real.php on line 66 Laravel

Boa tarde!

Estou com um problema ao fazer minha aplicação laravel funcionar.

Fiz a instalação do laravel via composer no servidor locaweb mas esta dando este erro

Warning: require(/home/storage/9/87/59/Usuario/public_html/vendor/composer/../laravel/framework/src/Illuminate/Foundation/helpers.php): failed to open stream: No such file or directory in /home/storage/9/87/59/Usuario/public_html/vendor/composer/autoload_real.php on line 66Fatal error: require(): Failed opening required '/home/storage/9/87/59/Usuario/public_html/vendor/composer/../laravel/framework/src/Illuminate/Foundation/helpers.php' (include_path='.:/usr/share/pear71:/usr/share/php71') in /home/storage/9/87/59/Usuario/public_html/vendor/composer/autoload_real.php on line 66

A pagina autoload_real.php:

	Alguém já teve este problema?
