Open php.ini file and you can find ;extension=php_fileinfo.dll remove the semi-coloumn to extension=php_fileinfo.dll will work perfectly then restart the your apache server or xampp ,wampp whatever environment you are using
I think is the WAMP Web Server's Bug. I switched to XAMPP Web Server and it works fine.
Thanks alot by the way.
uncomment this line in php.ini into php folder.
extension=php_fileinfo.dll
and restart the server(enter 'php artisan serve' again). This way will works!
