这是我第一次访问GitHub,我没有使用控制台的经验。我在MacBook上使用Bash。当我尝试访问GitHub时,我得到了这个:

git clone git@github.com: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页面上关于拒绝许可的说明进行操作。

当我使用ssh -vT git@github.com时,我得到以下结果:

OpenSSH_6.2p2, OSSLShim 0.9.8r 8 Dec 2011

接下来,eval "$(ssh-agent -s)"返回"Agent pid 2314", 但是ssh-add -l返回“代理没有身份”。

这就是我被困住的地方。

2019年macOS Sierra & High Sierra & Catalina的答案:

PS:大多数其他答案会让你创建一个新的ssh密钥…但你不需要这样做:)

正如https://openradar.appspot.com/27348363上详细描述的那样,macOS/OS X直到Yosemite曾经记住命令SSH -add -K <key>添加的SSH密钥

下面是我为了让它起作用而采取的4个步骤:

1: ssh-add ~/。ssh/PATH_TO_YOUR_SSH_PRIVATE_KEY(例如~/.ssh/id_rsa)

2:在“~/.ssh/config”中增加如下内容

Host * 
  AddKeysToAgent yes
  UseKeychain yes
  IdentityFile PATH_TO_YOUR_SSH_PRIVATE_KEY (e.g. ~/.ssh/id_rsa)

3:确保删除任何使用osxkeychain helper的gitconfig条目:

4:重启终端生效。

其他回答

我意识到的另一个元素是。ssh文件夹通常创建在Mac OS X /Users/的根文件夹中。如果您尝试从另一个文件夹使用ssh -vT git@github.com,即使您添加了正确的密钥,它也会给您一个错误。

您需要从当前文件夹中再次添加密钥(ssh-add '正确的路径到id_rsa')以成功进行身份验证(假设您已经将密钥上传到Git中的配置文件中)

详情请在此回答。

总而言之,当ssh-add -l返回“代理没有身份”时,这意味着ssh使用的密钥(存储在~/。ssh / id_rsa ~ /。Ssh /id_dsa等)要么丢失,Ssh -agent(身份验证代理)不知道它们,要么它们的权限设置不正确(例如,world writable)。

如果您的密钥丢失或没有生成任何密钥,请使用ssh-keygen -t rsa,然后ssh-add来添加密钥。

如果密钥存在,但ssh-agent不知道(比如密钥在非标准文件夹中),则使用ssh-add /path/to/my-non-standard-ssh-folder/id_rsa添加密钥。

如果您在ssh-add或ssh-agent上遇到问题,请参阅此答案。

有时检查~/.ssh/config可能很有用

应该是这样的

Host github.com
 IdentityFile ~/.ssh/id_rsa

如果链接不同的密钥,Id_rsa可能不同。

这可能导致任何新终端,代理id是不同的。 您需要为代理添加私钥

$ ssh-add <path to your private key>

这也适用于我: Chmod 700 .ssh Chmod 600 .ssh/id_rsa . exe Chmod 644 .ssh/id_rsa.pub

然后,输入ssh-add ~/.ssh/id_rsa
