git报错`There is no tracking information for the current branch``

错误1：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  
If you wish to set tracking information for this branch you can do so with:

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

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

其中第一个master为远程分支的名字，第二个为本地分支的名字

错误2：fatal: refusing to merge unrelated histories

命令行输入：

git pull origin master --allow-unrelated-histories
