如何将代码从cloud9推送到Github？

​我试了很多次，但都失败了。我的步骤如下所示

在my github中添加cloud9的SSH密钥，并将cloud 9与my github连接

新的回购协议称为

git@github.com：XXX/XXX.git

​

在cloud 9中输入文件

git远程添加源git@github.com：XXX/XXX.git

​​

git推送-u原始主机​

---

这是典型的在GitHub端创建的非空的新回购协议（意思是使用

README.md

或

许可证

或…）

---

如果您尝试创建一个实际上为空的GitHub repo，您将不会看到错误消息，也不需要在推之前执行

git push

尝试在推之前执行

git pull origin master

。谢谢！信息技术worked@QiyuZhang伟大的别忘了读书

Can some one help me? Thanks a lot!
