1.创建新项目上传

cd parent_dir //进入项目父目录mkdir gitDemo  //创建项目目录 gitDemocd gitDemo //进入项目目录 git init //初始化空的 git 仓库 touch README.md git add README.md //这两行添加简单的 README.md 文件 git commit -m "first commit" //提交时附加的信息 git remote add origin https://coding.net/codingTutorial/gitDemo.git //添加一个名为 origin 的远端（ url 为 git 地址） git push -u origin master //将该目录下的文件推送到远端（origin）上的 "master" 分支

可能会遇到的问题

a.如果是首次使用，会提示你先设置好用户名和邮箱，可以在 cmd 中输入：

  git config --global user.email "you@example.com"

  git config --global user.name "Your Name"

b.git push失败，出现以下提示

 ! [rejected]        master -> master (fetch first)

error: failed to push some refs to '/dummymare/Hello-World.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.

解决方法：

原因：本地版本和主干上的有差异先pull远端的版本，解决了冲突才能push

  git pull -u origin master

然后再

 git push -u origin master
