使用Git時如何解決權限被拒絕（公鑰）錯誤？ - How to solve Permission denied (publickey) error when using Git?

問題：

I'm on Mac Snow Leopard and I just installed git . 我在Mac Snow Leopard上，而且剛剛安裝了git 。

I just tried 我剛試過

git clone git@thechaw.com:cakebook.git

but that gives me this error: 但這給了我這個錯誤：

Initialized empty Git repository in `/Users/username/Documents/cakebook/.git/`
Permission denied (publickey).
fatal: The remote end hung up unexpectedly

What am I missing? 我想念什麼？
I've also tried doing ssh-keygen with no passphase but still same error. 我也嘗試過使用ssh-keygen而不設置密碼，可是仍然存在相同的錯誤。
