由于 publickey 推送到 github 时权限被拒绝

Question

我正在尝试将存储库推送到 github。我已经成功地将它推送到heroku。当我输入 git push origin master 时，我得到以下信息：

Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

我正在将代码推送到许多其他 github 存储库，因此我知道这不是我的计算机的普遍问题，我不想更改计算机上的默认设置。当我输入 git remote -v 时，我得到以下信息：

heroku  https://git.heroku.com/marketvault.git (fetch)
heroku  https://git.heroku.com/marketvault.git (push)
origin  git@github.com:codeundercoverdev/marketlaunch.git (fetch)
origin  git@github.com:codeundercoverdev/marketlaunch.git (push)

我该如何解决这个问题？我已经尝试过这篇文章：

GitHub Error Message - Permission denied (publickey)

但他们提到的所有内容都涉及更改我整个计算机上的设置，而我的计算机可以正常运行我目前在 GitHub 上拥有的至少 20 个其他应用程序。

运行ssh -Tvvv git@github.com verify的结果：

确保您的私钥生成的公钥与分配给您在 github 上的帐户的公钥相同：

ssh-keygen -yf ~/.ssh/id_rsa

应该打印在您的~/.ssh/id_rsa.pub 中可用的相同内容，并且应该在your github account 中提供相同的内容。
