我想从它的开发分支安装typerex。但是我在克隆它时遇到了麻烦,如下所示:
~:~$ git clone git@github.com:OCamlPro/typerex.git
Cloning into 'typerex'...
The authenticity of host 'github.com (204.232.175.90)' 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,204.232.175.90' (RSA) to the list of known hosts.

fatal: The remote end hung up unexpectedly
有谁知道该怎么做?
