Git新建本地分支與遠程分支關聯問題：git branch --set-upstream
git在本地新建分支， push到remote服務器上之後，再次pull下來的時候，如果不做處理會報以下提示：
You asked me to pull without telling me which branch you
want to merge with, and 'branch.production.merge' in
your configuration file does not tell me, either. Please
specify which branch you want to use on the command line and
try again (e.g. 'git pull <repository> <refspec>').
See git-pull(1) for details.
If you often merge with the same branch, you may want to
use something like the following in your configuration file:
[branch "debug"]
remote = <nickname>
merge = <remote-ref>
[remote "<nickname>"]
url = <url>
fetch = <refspec>
See git-config(1) for details.git本地新建一個分支後，必須要做遠程分支關聯。如果沒有關聯，git會在下面的操作中提示你顯示的添加關聯。關聯目的是如果在本地分支下操作： git pull, git push ，不需要指定在命令行指定遠程的分支．推送到遠程分支後，你只要沒有顯示指定，git pull的時候，就會提示你。
解決方法：
使用命令git branch --set-upstream ;實例如下，其中debug爲創建的分支
git branch --set-upstream debug origin/debug
命令的最終修改都是針對config文件。
使用－－set-upstream去跟蹤遠程分支。
