Fatal error: require_once(): Failed opening required '/home/songhaowen/haoche/app/application/library/Jpush/src/JPush/Http.php' (include_path='.:/usr/share/pear:/usr/share/php') in /home/songhaowen/haoche/app/application/library/Jpush/autoload.php on line 7

按如下代码调用，调试报错，请教一下是不是我哪里出错了？谢谢
$client = new \JPush\Client(JPUSH_KEY, JPUSH_SECERT);
$device = $client->device();
$device->addTags($registration_id, $tag);
