启动服务的时候就出现了这个问题，求各路大神给指点一下~

D:\wamp\www\sot>php artisan serve
{"error":{"type":"ErrorException","message":"file_put_contents(\/meta\/services.
json): failed to open stream: No such file or directory","file":"D:\wamp\www\
sot\bootstrap\compiled.php","line":4158}}

提示这里有问题，然后我看了下那个文件。
public function put($path, $contents)
{
return file_put_contents($path, $contents);
}
这是 第4158行的内容，不知道该如何操作啊。求指点。

我把composer给 update了一下，执行到最后还是 出现 这个错误。
