There is no tracking information for the current branch.

新建本地分支后将本地分支推送到远程库, 使用git pull 或者 git push 的时候报错

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 wi

    git branch --set-upstream-to=origin/<branch> master

 

是因为本地分支和远程分支没有建立联系  (使用git branch -vv  可以查看本地分支和远程分支的关联关系)  .根据命令行提示只需要执行以下命令即可

$ git branch --set-upstream-to=origin/master master

然后就可以使用拉取的命令了。

第二个问题：fatal: refusing to merge unrelated histories

git pull origin master --allow-unrelated-histories
