拒绝Github权限：ssh添加代理没有标识

Question

这是我第一次访问GitHub，我没有使用控制台的经验。我正在使用Bash的MacBook上。当我尝试访问GitHub时，我得到的是：

git clone [e-mail]:dhulihan/league-of-legends-data-scraper.git
Cloning into 'league-of-legends-data-scraper'...
Permission denied (publickey).
fatal: Could not read from remote repository.

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

我试着按照Github页面上关于拒绝权限的说明操作。

OpenSSH_6.2p2, OSSLShim 0.9.8r 8 Dec 2011

这就是我被困住的地方。

详细情况请参阅本答案。

总之，当ssh-add-l返回“代理没有标识”时，这意味着ssh使用的密钥（存储在~/.ssh/id_rsa、~/.ssh/id_dsa等文件中）丢失，作为身份验证代理的ssh-agent不知道这些密钥，或者它们的权限设置不正确（例如，world ；writable）。

如果缺少密钥或未生成任何密钥，请使用ssh-keygen-t rsa，然后使用ssh-add添加它们。

如果存在密钥，但ssh-agent不知道这些密钥（如它们位于非标准文件夹中），请使用ssh-add/path/to/my-non-standard-ssh-folder/id_rsa添加这些密钥。

如果使用ssh-add或ssh-agent遇到问题，请参阅此答案。
