尝试了一下午各种姿势安装Flarum，还是失败了。最后clone下代码，执行composer install进行安装。还是得到了以下错误:
[Composer\Downloader\TransportException]
The "http://packagist.org/p/provider-2017-01%245f868bee9804547072ef5db3bceced2841ae55afcf05c
f6fefb544502fa00f7f.json" file could not be downloaded (HTTP/1.1 302 Moved Temporarily)
里面的链接确实是404了。这个如何解决呢？
论坛里安装成功的哥们都是什么样的安装方式？
