git: No refs in common and none specified; doing nothing

git push 出错，在网上搜了一下，分享！

用gitolite新建项目，clone后首次push，可能会出现：

$ git push

No refs in common and none specified; doing nothing.

Perhaps you should specify a branch such as 'master'.

fatal: The remote end hung up unexpectedly

error: failed to push some refs to 'file:///xxxxxxx.git'

.这是Git 找不到你要提交的版本了。

解决办法：gitpush origin master
