git - 克隆 git repo 导致错误 - 主机密钥验证失败。致命：远端意外挂断

Question

我正在使用 SSH 将 git repo 克隆到我的 Web 服务器，但每次我收到此错误

$git clone git@github.com:aleccunningham/marjoram.git
Cloning into marjoram...
Host key verification failed.

我已经尝试了几乎所有在谷歌搜索中出现的东西，我对为什么这不起作用感到目瞪口呆。有任何想法吗？

另外，我没有使用像 Jenkins 这样的东西。

Answer 1

问题可能是您的 ~/.ssh/known_hosts 文件中不存在 Github。

将 GitHub 附加到授权主机列表中：

ssh-keyscan -H github.com >> ~/.ssh/known_hosts

Answer 2

已解决问题...您需要将 ssh 公钥添加到您的 github 帐户。

1. 验证 ssh 密钥是否已正确设置。
   1. 跑ssh-keygen
   2. 输入密码（保持默认路径 - ~/.ssh/id_rsa）
2. 将公钥 ( ~/.ssh/id_rsa.pub) 添加到 github 帐户
3. 试试git clone。有用！

初始状态（公钥未添加到 git hub 帐户）

foo@bn18-251:~$ rm -rf test
foo@bn18-251:~$ ls
foo@bn18-251:~$ git clone git@github.com:devendra-d-chavan/test.git
Cloning into 'test'...
Permission denied (publickey).
fatal: The remote end hung up unexpectedly
foo@bn18-251:~$

现在，将公钥添加~/.ssh/id_rsa.pub到 github 帐户（我使用过cat ~/.ssh/id_rsa.pub）

foo@bn18-251:~$ ssh-keygen

好吧，从 sourceTree 我无法解决这个问题，但我从 bash 创建了 sshkey，至少它可以从 git-bash 工作。

Answer 4

我也遇到了同样的问题，解决方法很简单，从cmd或者其他windows命令行工具改成git bash就可以了。Windows 有时无法很好地处理 git npm 依赖项。
