this is my little os for study git config --list 出现的问题 1 git pull You asked me to pull without telling me which branch you want to merge with, and 'branch.master.merge' in your configuration file does not tell me either. Please name which branch you want to merge on the command line and try again (e.g. 'git pull <repository> <refspec>'). See git-pull(1) for details on the refspec. If you often merge with the same branch, you may want to configure the following variables in your configuration file: branch.master.remote = <nickname> branch.master.merge = <remote-ref> remote.<nickname>.url = <url> remote.<nickname>.fetch = <refspec> See git-config(1) for details. 1 把现有的branch删除，重新建立过
