gitlab 错误处理 error: failed to push some refs to 'file:///xxxxxxx.git'

gitlab 错误处理
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：

git push origin master
