* [new branch] master -> origin/master
There is no tracking information for the current branch.
Please specify which branch you want to merge with.
See git-pull(1) for details.
git pull <remote> <branch>
If you wish to set tracking information for this branch you can do so with:
git branch --set-upstream-to=<remote>/<branch> master
执行本地关联远程分支命令：
git branch --set-upstream-to=origin/remote_branch your_branch
其中，origin/remote_branch是你本地分支对应的远程分支；your_branch是你当前的本地分支。
（
$git branch :本地分支
$git branch -vv（两个v），就能够看到本地分支跟踪的远程分支。
）
再执行远程提交：
$ git push origin master
成功。
