OS X el captain (10.11.4) 下装 flarum 用的 PHP 7 报错了

目前已有

$ php -v

PHP 7.0.3 (cli) (built: Feb 6 2016 03:16:24) ( NTS )

$ brew --version

$ httpd -v

$ mysql --version
mysql Ver 15.1 Distrib 10.1.11-MariaDB, for osx10.11 (x86_64) using readline 5.1

现在的环境出现下面这个错误是咋回事儿

Notice: Undefined property: stdClass::$data in /Users/my-username/Sites/vendor/flarum/core/src/Http/Controller/ClientView.php on line 326

需要看我的 httpd.conf 和 httpd-vhosts.conf 吗？
