期间出错：

出错了。
很明显是：
本地没有update到最新版本的项目（git上有README.md文件没下载下来）
本地直接push所以会出错。
【解决过程】
1.看到提示里面，感觉是本地的代码不是最新的。
所以觉得应该是类似于svn中的，先update一下，再去commit，估计就可以了。
所以先去pull试试：
结果直接pull好像是不对的：

$ git pull

* [new branch] master -> origin/master
You asked me to pull without telling me which branch you
want to merge with, and 'branch.master.merge' in
your configuration file does not tell me, either. Please
specify which branch you want to use on the command line and
try again (e.g. 'git pull <repository> <refspec>').
See git-pull(1) for details.
If you often merge with the same branch, you may want to
use something like the following in your configuration file:
[branch "master"]
remote = <nickname>
merge = <remote-ref>
[remote "<nickname>"]
url = <url>
fetch = <refspec>
See git-config(1) for details.

看来需要先搞懂pull的用法。
2.估计是指定对应的要pull的目标即可。
所以再去试试pull origin：

$ 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.

也还是不对。
有空再继续搞懂原理后再弄。。
3.搜：
error: failed to push some refs to
参考：
github – git error: failed to push some refs to – Stack Overflow
去试试：

可以看到，此时已经把github上最新的文件下载下来了：
即，那个README.md文件。
4.接着再去：
git push origin master

即可成功把本地的文件都上传到github上面去了。
5.此时再去github网站上也就可以看到对应文件了：
【注意】
此处注意到，此时所用的用户，是那个当前电脑的名词，很长的那个，而不是crifan：
那是因为之前那个：
【已解决】cygwin中用git去config配置用户名和邮箱出错：error: cannot run vi: No such file or directory
时，当时没有解决掉用户名的问题就去commit了。
所以用户名是当时的，当前电脑的用户名。而不是我自己的crifan。
而此时已经解决了修改用户名的问题。
等下次再去上传，或许可以把用户名变过来了。
