请有人可以帮助解决此问题。预先感谢

Answer 1

这不是作曲家问题，作曲家只会从Laravel Framework中运行上Update命令。

尝试" PHP Artisan Clear-Compiled"，您会遇到相同的错误。

检查您的Laravel安装（此问题应该有所帮助：我的作曲家不会与Laravel 4完全更新，它与Artisan陷入困境）

Answer 2

    delete the composer.lock file
run
    composer dump-autoload
    php artisan dump-autoload
then 
composer update
