github 本地上传远程库失败（error: failed to push some refs to '~~~~~'）

原因：
本地没有更新到最新版本的项目，github远程资源和本地不一致。

解决过程：
1、将远程最新项目下载到本地

（1）尝试git pull，出错

Sunshine@Sunshine-pc MINGW64 /d/gitProjects/DataProcess (master)
$ git pull
warning: no common commits
remote: Enumerating objects: 3, done.
remote: Counting objects: 100% (3/3), done.
remote: Total 3 (delta 0), reused 0 (delta 0), pack-reused 0
Unpacking objects: 100% (3/3), done.
From github.com:sunmingming99/DataProcess
 * [new branch]      master     -> origin/master
There is no tracking information for the current branch.
Please specify which branch you want to merge with.
See git-pull(1) for details.

    git pull  

If you wish to set tracking information for this branch you can do so with:

    git branch --set-upstream-to=origin/ master

（2）尝试git pull origin，依然不正确

Sunshine@Sunshine-pc MINGW64 /d/gitProjects/DataProcess (master)
$ git pull origin
You asked to pull from the remote 'origin', but did not specify
a branch. Because this is not the default configured remote
for your current branch, you must specify a branch on the command line.

Sunshine@Sunshine-pc MINGW64 /d/gitProjects/DataProcess (master)
$

（3）git pull --rebase origin master，正确

Sunshine@Sunshine-pc MINGW64 /d/gitProjects/DataProcess (master)
$ git pull --rebase origin master
From github.com:sunmingming99/DataProcess
 * branch            master     -> FETCH_HEAD
First, rewinding head to replay your work on top of it...
Applying: commite all files

2、push 到远程库

Sunshine@Sunshine-pc MINGW64 /d/gitProjects/DataProcess (master)
$ git push -u origin master
