出现问题的原因：

github中的README.md文件不在本地代码目录中

解决办法：

$ git pull --rebase origin master  #执行这一步。warning: no common commitsremote: Counting objects: 3, done.remote: Total 3 (delta 0), reused 0 (delta 0), pack-reused 0Unpacking objects: 100% (3/3), done.From github.com:Tuesdday/pythoncode * branch            master     -> FETCH_HEAD * [new branch]      master     -> origin/masterFirst, rewinding head to replay your work on top of it...Applying: practice

结果：

本地代码目录下出现 README.md 文档

此时 再执行以下操作 代码成功上传至github
