git项目不能push，显示灰色的，也不能切换分支。分支信息为：HEAD->d6b079ff。
1. 查分支状态
查看分支状态，显示不在任何分支上——“Not currently on any branch”：
E:\dwlijx_code\crm_pro>git status
Not currently on any branch.
nothing to commit, working tree clean
2. 建新分支dev
E:\dwlijx_code\crm_pro>git branch dev d6b079ff
根据各自项目的情况，建一个新分支就可以了。
3. 拉已有分支
E:\dwlijx_code\crm_pro>git checkout master
Previous HEAD position was d6b079f Merge branch 'master' of https://gitee.com/cowboy2014/crm_pro into HEAD
Switched to a new branch 'master'
Branch 'master' set up to track remote branch 'master' from 'cowboy'.
4. 合并到当前分支
E:\dwlijx_code\crm_pro>git merge dev
Updating eabaccc..d6b079f

5. 验状态
E:\dwlijx_code\crm_pro>git status
On branch master
Your branch is ahead of 'cowboy/master' by 2 commits.
(use "git push" to publish your local commits)
nothing to commit, working tree clean
看到当前本地代码已经是master分支了，然后就可以再push到master分支了。
