git pull报错:Auto Merge Failed; Fix Conflicts and Then Commit the Result.

1.出错场景:

协同开发时,我们从远程服务器上pull下代码的时候,出现以下提示信息:
Auto Merge Failed; Fix Conflicts and Then Commit the Result.

2.原因分析:

利用git status,输出如下:

root@hyk-virt:/etc# git status

On branch master # Your branch and ‘origin/master’ have diverged, # and have 2 and 2 different commits each, respectively. # # Unmerged paths: # (use “git add/rm …” as appropriate to mark resolution) # # both modified: apt/sources.list # # Changes not staged for commit: # (use “git add …” to update what will be committed) # (use “git checkout – …” to discard changes in working directory) # # modified: cups/subscriptions.conf # modified: cups/subscriptions.conf.O # modified: mtab # modified: update-manager/release-upgrades

no changes added to commit (use “git add” and/or “git commit -a”)

从git status的结果可以发现:其中sources.list这个文件存在合并冲突
而进一步分析git pull的原理,实际上git pull是分了两步走的,(1)从远程pull下origin/master分支(2)将远程的origin/master分支与本地master分支进行合并
以上的错误,是出在了第二步骤

3.解决方法

方法一:如果我们确定远程的分支正好是我们需要的,而本地的分支上的修改比较陈旧或者不正确,那么可以直接丢弃本地分支内容,运行如下命令(看需要决定是否需要运行git fetch取得远程分支):
:gitresethardorigin/master:git reset –hard ORIG_HEAD
解释:
git-reset - Reset current HEAD to the specified state

–hard
Resets the index and working tree. Any changes to tracked files
in the working tree since are discarded.

方法二:我们不能丢弃本地修改,因为其中的某些内容的确是我们需要的,此时需要对unmerged的文件进行手动修改,删掉其中冲突的部分,然后运行如下命令
:gitaddfilename:git commit -m “message”

方法三:如果我们觉得合并以后的文件内容比价混乱,想要废弃这次合并,回到合并之前的状态,那么可以运行如下命令:
$:git reset –hard HEAD
