emmmmmm 报错信息是这样的

$ git push -u origin master
Warning: Permanently added the RSA host key for IP address '13.229.188.59' to the list of known hosts.
To github.com:magicmshing/Tm.git
 ! [rejected]        master -> master (non-fast-forward)

嗯嗯，报错信息有点多啊，，，
先看第一条Warning: Permanently added the RSA host key for IP address '13.229.188.59' to the list of known hosts.叫我们把那个地址添加添加到本地。
那就添加呗

linux的话，就在 /etc/hosts添加：

# set github
13.229.188.59 github.com

windows的话就编辑/c/Windows/System32/drivers/etc/hosts文件

也是添加一样的内容

记住无论是linux还是windows都需要管理员权限才能修改

再次运行

$ git push -u origin master
To github.com:magicmshing/Tm.git
 ! [rejected]        master -> master (non-fast-forward)
error: failed to push some refs to 'git@github.com:magicmshing/Tm.git'

还是有报错，嗯嗯，本人是个英语渣，慢慢吭。

嗯嗯，经过我漫长的百度之后，发现貌似是创建库的时候我写了一个README.md的Markdown文件

解决： 把仓库下拉到本地，在上传

$ git pull --rebase origin master
From github.com:magicmshing/Tm
 * branch            master     -> FETCH_HEAD
 * [new branch]      master     -> origin/master
First, rewinding head to replay your work on top of it...
Applying: first commit my wechat miniprogram

然后再继续上传

$ git push -u origin master

   c4c56ce..0dbd8a6  master -> master
Branch 'master' set up to track remote branch 'master' from 'origin'.

就成功了。我这应该只是坑之一，也只是解决的方法之一。
