某些功能报错：Call to a member function on a non-object已解决 悬赏5积分

出现蛮多次的：

Call to a member function getProductBuildPairs() on a non-object

Call to a member function getById() on a non-object 

Call to a member function getProjectBuilds() on a non-object

 the control file /var/www/ZT/module/release/control.php not found

都是一些莫名其妙的错误。按照文档部署的。
