! [rejected]  master -> master (non-fast-forward)

error: failed to push some refs to 'http://git.oschina.net/lightyear/nfc_beta2.git'

hint: Updates were rejected because a pushed branch tip is behind its remote

hint: counterpart. Check out this branch and merge the remote changes

hint: (e.g. 'git pull') before pushing again.

hint: See the 'Note about fast-forwards' in 'git push --help' for details.

好久没有提交git，今天一提交发现和远程分支有了冲突，看了下描述。大致意思是:

由于你推送的分支落后于远程分支，更新失败。这说明你上次pull之后有人改动了源文件.

但是使用pull命令并没有生效，

于是参考了git fetch 拉取而不合并

git pull origin master

结果完成了提交.

git log

能够看到别人提交的记录以及自己的改动.
