我试图在我从 git hub 克隆的文件夹中运行以下命令：
git submodule update --init --recursive
然后我收到错误消息，说权限被拒绝(公钥( 我尝试搜索此内容并运行此评论以创建ssh密钥：
ssh-keygen -t rsa -C "xxx@xxx.com"
并通过网站添加了ssh密钥，并运行以下命令以检查是否已修复：
ssh -T git@github.com
但它告诉我我已经成功进行身份验证，但 GitHub 剂量不提供 shell 访问。然后我运行以下命令进行调试：
ssh -vT git@github.com
这是输出：

有人知道如何解决这个问题吗？ 多谢！
我在帖子中运行了第一个命令：
git submodule update --init --recursive，它仍然告诉我Permission denied (publickey)
这取决于子模块的 URL，您可以在存储库的.gitmodules文件中读取该 URL。
或者它可能取决于一个子模块的子模块的 URL，但是如果没有克隆子模块，如果立即显示错误，则问题应仅限于直接的第一级子模块。
因此，请仔细检查.gitmodules文件中存在的 URL：其中一个可能引用您的身份验证无法访问的专用存储库。
这很好，不是错误。
这意味着您的密钥可以工作，您应该能够使用git命令访问您的存储库。
即使 git 使用 ssh 协议和登录机制，你也不允许在 Github 的服务器上通过 ssh 进入完整的 shell 会话。但无论如何你都不需要它。
