fatal: remote origin already exists

今天使用Idea 上传项目到已创建的github repository提示 fatal:remote origin already exists。
解决方法：
git bash 中输入：

>git remote --verbose

删除远程的origin

>git remote remove origin

查看远程origin

>git remote --verbose

>git init
>git add README.md
>git commit -m "first commit"
>git remote add origin https://github.com/username/remote-repository
>git remote --verbose

git push -u origin master
