Scrapyd 本地部署出现 Bug: twisted.web.error.UnsupportedMethod: Expected one of [b'HEAD', b'object', b'POST']

基本上都是正常操作：启动 Scrapyd 服务，修改.cfg 文件，curl 操作 API，然后就出现了如下的 Bug(我在命令行粘贴下来的)：

2019-04-06T16:31:57+0800 [_GenericHTTPChannelProtocol,35,127.0.0.1] Unhandled Error

  看错误提示，我进入相关文件查看后，找不出异样(emmm......承认自己处理问题的能力), 不知道大家有没有遇到过相同的问题。
