在尝试运行 sudo npm install -g aws-amplify/cli 时，我收到错误The authenticity of host 'github.com (192.30.255.112)' can't be established

阅读The authenticity of host 'github.com (192.30.252.128)' can't be established 后，我运行了 ssh -T git@github.com 并获得了 Permission denied (publickey)。错误。现在，如果我再次运行 aws-amplify 安装，我会得到：

npm ERR! code 128
npm ERR! command failed
npm ERR! command git ls-remote ssh://git@github.com/aws-amplify/cli.git
npm ERR! git@github.com: Permission denied (publickey).
npm ERR! fatal: Could not read from remote repository.

帮助？

标签： github ssh aws-amplify

【解决方案1】：

至少从完成您的 known_hosts 开始：

ssh-keyscan -Ht rsa github.com,192.30.255.112 ~/.ssh/known_hosts

（虽然你可能想double-check the fingerprint with nmap first）

其次，尝试ssh -Tv git@github.com 看看考虑了哪些键。
确保拥有例如~/.ssh/id_rsa.pub registered to your account。

或者，强制 npm 使用 HTTPS URL：

 git config --global url."https://github.com/".insteadOf git@github.com:
