git pull push没有指定branch报错的解决方法

从远程分支 checkout 出来的本地分支，称为_跟踪分支(tracking branch)_。跟踪分支是一种和远程分支有直接联系的本地分支。在跟踪分支里输入Git push，Git 会自行推断应该向哪个服务器的哪个分支推送数据。反过来，在这些分支里运行git pull 会获取所有远程索引，并把它们的数据都合并到本地分支中来。在克隆仓库时，Git 通常会自动创建一个名为 master 的分支来跟踪 origin/master。这正是git push 和 git pull 一开始就能正常工作的原因。当然，你可以随心所欲地设定为其它跟踪分支，比如origin 上除了 master 之外的其它分支。刚才我们已经看到了这样的一个例子：git checkout -b [分支名] [远程名]/[分支名]。[plain] view plain copyshuohailhl@SHUOHAILHL-PC /f/ggg/jingwei (master)  $ git checkout --track origin/br-2.1.2.1  Branch br-2.1.2.1 set up to track remote branch br-2.1.2.1 from origin.  Switched to a new branch 'br-2.1.2.1'    shuohailhl@SHUOHAILHL-PC /f/ggg/jingwei (br-2.1.2.1)  $ git status  # On branch br-2.1.2.1  nothing to commit, working directory clean    shuohailhl@SHUOHAILHL-PC /f/ggg/jingwei (br-2.1.2.1)  $ git br  * br-2.1.2.1    br-2.1.2.2    master    shuohailhl@SHUOHAILHL-PC /f/ggg/jingwei (br-2.1.2.1)  删掉刚才track的分支[plain] view plain copyshuohailhl@SHUOHAILHL-PC /f/ggg/jingwei (master)  $ git br    br-2.1.2.1    br-2.1.2.2  * master    shuohailhl@SHUOHAILHL-PC /f/ggg/jingwei (master)  $ git status  # On branch master  nothing to commit, working directory clean    shuohailhl@SHUOHAILHL-PC /f/ggg/jingwei (master)  $ git branch -d br-2.1.2.1  warning: deleting branch 'br-2.1.2.1' that has been merged to          'refs/remotes/origin/br-2.1.2.1', but not yet merged to HEAD.  Deleted branch br-2.1.2.1 (was cec094b).    shuohailhl@SHUOHAILHL-PC /f/ggg/jingwei (master)  $ git br -v    br-2.1.2.2 1dfeab3 [behind 9] 升级META客户端2.1.4.4  * master    89700a3 optimize upload file  使用checkout命令，创建新的分支 br-2.1.2.1，跟踪远程的origin/br-2.1.2.1[plain] view plain copyshuohailhl@SHUOHAILHL-PC /f/ggg/jingwei (master)  $git checkout -b br-2.1.1.1  origin/br-2.1.2.1Branch br-2.1.1.1 set up to track remote branch br-2.1.2.1 from origin.  Switched to a new branch 'br-2.1.1.1'    shuohailhl@SHUOHAILHL-PC /f/ggg/jingwei (br-2.1.1.1)  $ git status  # On branch br-2.1.1.1  nothing to commit, working directory clean    shuohailhl@SHUOHAILHL-PC /f/ggg/jingwei (br-2.1.1.1)    $ git branch -a  * br-2.1.1.1    br-2.1.2.2    master    remotes/origin/HEAD -> origin/master    remotes/origin/br-2.1.2.1    remotes/origin/br-2.1.2.2    remotes/origin/br-2.1.3    remotes/origin/master
