remote: error: the work tree to HEAD.
   remote: error: 

 remote: error: You can set 'receive.denyCurrentBranch' configuration variable to 

 remote: error: 'ignore' or 'warn' in the remote repository to allow pushing into 

 remote: error: its current branch; however, this is not recommended unless you

   remote: error: other way. 

remote: error: To squelch this message and still keep the default behaviour, set
   remote: error: 'receive.denyCurrentBranch' configuration variable to 'refuse'.
   To ...

需要配置一下ｇｉｔ的接收配置，执行如下命令即可正确提交：

git config receive.denyCurrentBranch ignore
