ruby-on-rails - 无法推送到 github，ssh : Could not resolve hostname

Question

我无法通过这个，已经多次重新制作存储库，制作了 ssh key

--------------
demo_app <username>$ git remote add origin git@github.com:<username>/demo_app.git

fatal: remote origin already exists.

$ git push -u origin master
---
ssh: Could not resolve hostname git: nodename nor servname provided, or not known
---
fatal: Could not read from remote repository.
---
Please make sure you have the correct access rights
---
and the repository exists.

Checked ssh keys

$ ssh -T git@github.com

Hi <username>! You've successfully authenticated, but GitHub does not provide shell access.

仍然收到相同的消息。

不要添加新的 Remote ，而是尝试使用以下命令更改现有的 Remote :

git remote set-url origin git@github.com:<username>/demo_app.git

编辑:所以，这里有一些命令可以让它在不丢失代码的情况下工作。

1. rm -rf .git
2. git init .
3. git remote add origin git@github.com:<username>/demo_app.git
4. git commit --allow-empty -m 'First commit'
5. git push origin master
