Git 提示fatal: remote origin already exists 错误解决办法

1、先删除远程 Git 仓库

git remote rm origin

2、再添加远程 Git 仓库

git remote add origin https://github.com/XXXXXXXXXXX/design-patterns.git

注： 如果执行 git remote rm origin 报错的话，我们可以手动修改gitconfig文件的内容

        vi .git/config

        把 [remote “origin”] 那一行删掉就好了。

注：若出现“Updates were rejected because the tip of your current branch is behind”
