上传本地代码到GitHub远程仓库

1、在本地文件目录下，选中要提交的文件，右键点击Git Bash Here进入文件目录



2、链接远程仓库：git remote add origin git@github.com:134251796/lxy.git（远程仓库地址）
3、添加当前目录的所有文件到暂存区：git add .(点的意思是所有文件)
4、提交文件：git commit -m “描述信息”
5、上传本地分支到远程仓库：git push -u origin master
【注】如果git push报错 error:failed to push some refs to 'git@github.com:134251796/lxy.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.

原因： 
GitHub远程仓库中的README.md文件不在本地仓库中。 
解决方案：

$ git pull --rebase origin master
$ git push -u origin master
