写了一天代码，提交时报错。拉取也不行
Can't Update No tracked branch configured for branch master or the branch doesn't exist. To make your branch track a remote branch call, for example, git branch --set-upstream-to=origin/master master (show balloon)
原因：
Git 不知道你要pull远程的哪个分支. 如果此时使用命令行,输入 git pull 可以查看详细的错误提示为: There is no tracking information for the current branch.
解决方法：
提交代码到新仓库时报错，解决方法：
Alt + F12 呼出Terminal，输入以下指令：
git branch --set-upstream-to=origin/master
