新手刚用Git，Push的时候出现错误：
To ssh://*******.com/HRC
e06a5d2..265df95 master -> master
! [rejected] R8 -> R8 (non-fast-forward)
! [rejected] reserved -> reserved (non-fast-forwaritolite@******.com)
error: failed to push some refs to 'ssh://g/HRC'
hint: Updates were rejected because a pushed branch tip is behind its remote

hint: specify branches to push or set the 'push.default' configuration

根据他的提示，我做了如下操作，
git config --global push.default "current"
然后继续push就成功了。
