Git:不能 pull

Question

首先，我应该说我运行的是 Windows 7。

因此，今天早上我尝试像往常一样从我的存储库中提取数据，但我做不到。我得到了错误:

The authenticity of host 'github.com (207.97.227.239)' can't be established.
RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'github.com,207.97.227.239' (RSA) to the list of know
n hosts.
Permission denied (publickey).
fatal: The remote end hung up unexpectedly

为此，git's documentation说:

现在，我不太确定如何访问 ~/.ssh 文件夹，因为我在 Windows 上(也可以在网上找到任何东西)所以我尝试运行 ssh-keygen 并按回车键。但这也不起作用。

C:\Users\Ceasar\Desktop\lemonwi.se\lw_reviews\src>ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (//.ssh/id_rsa):
Could not create directory '//.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
open //.ssh/id_rsa failed: No such host or network path.
Saving the key failed: //.ssh/id_rsa.

此时，我尝试搜索错误，但找不到任何运气。

谁能帮我恢复从 repo 中 pull 的能力？

我怀疑这可能是 PATH 变量的问题，因为我几天前不小心删除了它们并且只恢复了我记得的内容，但我完全不确定这里发生了什么。

编辑:使用 Git Bash，我导航到 ./ssh 并制作了一个新 key 。

Ceasar@BAUTISTC-PC ~ (master)
$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/Ceasar/.ssh/id_rsa):
/c/Users/Ceasar/.ssh/id_rsa already exists.
Overwrite (y/n)? y
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/Ceasar/.ssh/id_rsa.
Your public key has been saved in /c/Users/Ceasar/.ssh/id_rsa.pub.
The key fingerprint is:
10:b5:03:59:ec:02:18:fd:90:3c:69:1e:02:a4:93:2d Ceasar@BAUTISTC-PC

然后我将其复制到 https://github.com/account/ssh但我仍然遇到错误:

C:\Users\Ceasar\Desktop>git pull origin master
Permission denied (publickey).
fatal: The remote end hung up unexpectedly 

运行 ssh -vT git@github.com 给我:

编辑 2:所以使用 Git Bash，我可以成功 pull ，这意味着这与 Windows 不知道主目录在哪里有关。尽管根据以下内容，Windows 并未明确具有 home 变量:http://en.wikipedia.org/wiki/Environment_variable#Default_Values_on_Microsoft_Windows所以我还是有点困惑。

Answer 1

管理您的 windows 环境变量并添加 'home' -> 'c:\users\your-windows-account'。重新启动命令控制台。
