碰到一个问题，我试着发布到 cocoaPods 上去，执行pod --verbose spec lint这个命令的时候是验证通过了的，但每次pod trunk push都出现这个错误You are not allowed to push new versions for this pod，详细：

-> "HTTP/1.1 403 Forbidden\r\n"
-> "Date: Thu, 10 Mar 2016 03:37:03 GMT\r\n"
-> "Connection: keep-alive\r\n"
-> "Strict-Transport-Security: max-age=31536000\r\n"
-> "Content-Type: application/json\r\n"
-> "Content-Length: 66\r\n"
-> "X-Content-Type-Options: nosniff\r\n"
-> "Server: thin 1.6.2 codename Doc Brown\r\n"
-> "Via: 1.1 vegur\r\n"
-> "\r\n"
reading 66 bytes...
-> "{\"error\":\"You are not allowed to push new versions for this pod.\"}"

有人知道是什么原因吗？
