* [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=origin/<branch> master看到第二个提示，我们现在知道了一种解决方案。也就是指定当前工作目录工作分支，跟远程的仓库，分支之间的链接关系。<br>
比如我们设置master对应远程仓库的master分支
git branch --set-upstream master origin/master
这样在我们每次想push或者pull的时候，只需要 输入git push 或者git pull即可。
在此之前，我们必须要指定想要push或者pull的远程分支。
git push origin master
git pull origin master.
