未找到“ComposerAutoloaderInitd00bfc7ec47fbf7b35605d09893589e5”类。 如何调试此错误？

Question

Please help me to come out from this error. It is generated by the following snippet:

?php

// autoload.php @generated by Composer

require_once __DIR__ . '/composer' . '/autoload_real.php';

return ComposerAutoloaderInitd00bfc7ec47fbf7b35605d09893589e5::getLoader()
