git pull origin master命令后發生沖突

問題說明：

$ git pull origin master

error: Pulling is not possible because you have unmerged files.
hint: Fix them up in the work tree, and then use 'git add/rm <file>'
hint: as appropriate to mark resolution and make a commit.
fatal: Exiting because of an unresolved conflict.

解決方法：

1.git pull會產生merge操作導致沖突，需要將沖突的文件resolve掉之后才能成功pull

所以執行下列命令即可：

git add -u
git commit -m "注釋"
git pull

2.放棄本地更改也可以解決沖突

放棄本地更改git reset --hard FETCH_HEAD，其中FETCH_HEAD表示上一次成功pull之后的commit點，然后git pull即可
