从 gitlab 拉/推导致权限被拒绝（公钥）答案

【问题标题】：pull/push from gitlab results in Permission denied (publickey)从 gitlab 拉/推导致权限被拒绝（公钥）
【发布时间】：2020-06-16 13:17:54
【问题描述】：

我同时使用 git bash 和 VS 代码连接到我的 gitlab 存储库。一切正常，直到我创建了一个新的存储库并尝试通过 git bash 在本地克隆它。我收到的错误是：

git@gitlab.com: Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.

我尝试更改 ./ssh 文件夹和公钥的权限，将 ssh 添加到代理，但这些都不起作用。

执行ssh -Tv <user name>@gitlab.com 显示以下输出：

首先，确保您拥有registered the content of id_rsa.pub to your GitLab SSH keys profile page。

如果它仍然不起作用，请尝试重新生成该密钥，无需密码（用于测试，并排除任何 ssh-agent 问题，该问题仅用于缓存密码）

ssh-keygen -m PEM -t rsa -P ""

确保您的 Git for Windows 是最新的 (2.27)。

确保set GIT_SSH=（意思是未设置GIT_SSH，不应指putty.exe）。
