我无法使用 SSH 从 github 克隆任何 repo。以下是控制台输出：

Cloning into 'js'...

fatal: Could not read from remote repository.

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

我做错了什么？谢谢

答案1

我做错了什么？

  1. 除非你有充分的理由，否则你的第一个错误可能是在本地机器上以 root 身份而不是普通用户身份登录签出 github repo。
  2. 您是否已在 github GUI 上为您的帐户声明了 rsa 公钥（单击您的图片 > 设置 > SSH 和 GPG 密钥）？您尝试的 repo 是公开的，因此除了 github 知道它之外，没有其他要求可以通过 ssh 克隆它。
  3. 如果您已经声明了密钥，您确定您没有使用个人帐户公共 RSA 密钥，而是使用了 root 使用的密钥（这又回到了第 1 点）吗？
