[iOS - Cocoapods] Authentication token is invalid or unverified

Before registering a cocoapods you can view the pods library info like：

$ pod trunk info Fabric

Fabric

    - Versions:

      - 1.2.1 (2014-05-19 22:07:59 UTC)

      - 1.2.2 (2014-05-19 22:08:07 UTC)

    - Owners:

      - Xiangwei Wang <billwangxw@gmail.com>

But you got the following error when:

$ pod trunk me

[!] Authentication token is invalid or unverified. Either verify it with the email that was sent or register a new session.

That means you hasn't registered yet, but I couldn't understand why I became a owner. Haha, anyway, just to register it as:

$ pod trunk register billwangxw@gmail.com 'Peter Wang' --description='iOS development'
