我遇到了问题。在我的实时服务器上传laravel 5.4之后，服务器在错误日志中给出了错误
[03-Nov-2017 09:41:10] PHP Fatal error: Couldn't execute method Composer\Autoload\ClassLoader::composer\autoload\classloader::loadclass in Unknown on line 0
[03-Nov-2017 09:41:15] PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 4096 bytes) in /home/hosting_users/skymoontiger/www/vendor/laravel/framework/src/Illuminate/Filesystem/Filesystem.php on line 41
我该怎么办？提前谢谢......
