Facebook PHP SDK 4.0根本不起作用-在Facebook类内部

晚安。

嗯，我的问题有点奇怪而且很长。我正在开发一个应用程序，我创建了一个开发环境来测试Facebook SDK PHP（4.0）。我的环境是Xubuntu，PHP 5.9，Apache2.2。所有人都在全力研究其他libs。我第一次犯错误已经好几天了，我的项目交付已经晚了。

请注意，他说找不到的文件就在那里。他到底在找什么。。。

我试过使用自动加载和composer。同样的错误，只是它在FacebookSession.php或FacebookRequest.php上。

问题是，我哪儿也做不到工作。

不管怎样，谢谢你的回复。

我讨厌Facebook现在
