解决The current branch is not configured for pull No value for key branch.master.merge found in config

1.在本地工程目录找到config文件（我的是在E:\rocket\rocket\.git）；

2.修改config文件内容为：

[core]
    repositoryformatversion = 0
    filemode = false
    logallrefupdates = true
    [branch "master"] 
        remote = origin 
        merge = refs/heads/master 
    [remote "origin"] 
        url = https://github.com/androidzhaoxiaogang/rocket.git   （修改为自己的url）
        fetch = +refs/heads/*:refs/remotes/origin/*

3.再执行pull方法，发现工作ok了
