在网页端修改仓库名称
在本机操作如下：
方案一：
git remote set-url origin [new_git_address]

方案二：
git remote rm origin
git remote add origin [new_git_address]

然后验证url的更改情况：
git remote -v

初次 push 的时候需要指定源
git push --set-upstream origin main

试错经历：
如果指定如下操作会出现只修改push源的情况

$ git remote set-url --push origin 
 https://github.com/liangsuli123/liangsuli123.github.io.git

$ git remote -v 
origin  https://github.com/xxx/xxx.github.io.git (fetch)
origin  https://github.com/xxx/xxx.github.io.git (push)


解决办法是先删除各个源，然后再按上面的方法二添加源

$ git remote rm origin                   # remove a first remote
$ git remote -v

# if you see your second origin
$ git remote rm origin                   # remove the second origin

$ git remote add origin <repo-url>       # add new origin

$ git remote -v                          # see all the remotes you have
