尝试为我的git生成一个公钥。使用Powershell。
PS>ssh-keygen -t rsa -b 4096 -C "my@emailaddress.com"
Generating public/private rsa key pair.
Enter file in which to save the key (//.ssh/id_rsa):
Could not create directory '//.ssh': Read-only file system
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Saving key "//.ssh/id_rsa" failed: No such file or directory
如果我提供文件的位置并运行
ssh -vT git@github.com
它不会检查要使用的公钥的自定义位置

PS>ssh-keygen -t rsa -b 4096 -C "my@emailaddress.com" Generating public/private rsa key pair.

命令无法保存您的密钥。在您具有写访问权限的位置指定文件：
ssh-keygen -t rsa -b 4096 -C "my@emailaddress.com" -f /path/to/key
这会保存/path/to/key中的私钥和/path/to/key.pub中的公钥。
成功的时候
而不是错误消息，你会看到类似的东西：
Your identification has been saved in /path/to/key. Your public key has been saved in /path/to/key.pub. The key fingerprint is: 76:f7:82:04:1e:64:eb:9c:df:dc:0a:6b:26:73:1b:2c The key's randomart image is: +--[ RSA 2048]----+ | o | | o . | | + | | + + | | S o . | | . = = o | | E * + o | | o.++ o | | *o.. | +-----------------+
然后，让ssh在自定义位置查找文件，
使用-i标志：
ssh -i /path/to/key -vT git@github.com
可替换地， 如果您正在运行身份验证代理， 您可以使用以下代码将密钥添加到代理：
ssh-add /path/to/key
代理商存储密钥后，您可以执行以下操作：
ssh -T git@github.com
响应应该类似于：
Hi USER! You've successfully authenticated, but GitHub does not provide shell access.
您可以继续使用以下命令克隆您的存储库：
git clone git@github.com:USER/REPO
答案 1 :(得分：1)
这对我有用：ssh-add '/home/user/.ssh/id_rsa'
答案 2 :(得分：0)
对我来说，ssh-keygen命令似乎仅在使用cmd时失败：
您的标识已保存在[...] /。ssh / id_rsa中。 fdopen [...] /。ssh / id_rsa.pub失败：没有这样的文件或目录
已生成私钥，但使用0个字节创建了公钥文件。
如果我在Windows的Git Bash中运行该命令，它将起作用。
