上传一个项目到GitHub

1. 首先在GitHub创建一个项目文件

2. 进入本地创建项目所在文件夹Git init创建本地Git 环境

3. Git add . 将项目加载到暂存区。

4. Git commit -m "备注描述内容"将项目加载到本地仓库区

5. git remote add origin https://gitee.com/MarchWood680/Block.git 关联本地库 同 远端库

6. git push -u origin master（-u表示刚开始远程仓库没有内容，有了内容之后就不用再写了）
   如果新建远程仓库不是空的，例如你勾选了 Initialize this repository with a README。那么你通过命令 $ git push -u origin master是会报错的，如下：

MarchWooddeMacBook-Pro:BlockTest marchwood$ git push -u origin master
To https://gitee.com/MarchWood680/Block.git
 ! [rejected]        master -> master (fetch first)
error: failed to push some refs to 'https://gitee.com/MarchWood680/Block.git'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.
MarchWooddeMacBook-Pro:BlockTest marchwood$ 

这是由于你新创建的那个仓库里面的README文件不在本地仓库目录中，这时我们可以通过以下命令先将内容合并以下：

git pull --rebase origin master

7. git push origin master提交本地项目到远端库
