git---如何解决The authenticity of host can't be established.

新生成密钥的时候，git clone或者push的时候，可能会报这样的错误：

```

The authenticity of host 'gitee.com (xxx.xxx.xxx.xxx)' can't be established.

ECDSA key fingerprint is SHA256:xxxxxxxxxxxxxxxxxxxxxxxx.

```

Google之后明白，文件夹内少了一个known_hosts文件，本来密钥文件应该是三个，现在只有两个，便报了这样的错误，此时输入yes回车之后，生成了缺少了的known_hosts文件，便可解决这个问题：

```

Are you sure you want to continue connecting (yes/no)? //输入yes，回车

Warning: Permanently added 'gitee.com,xxx.xxx.xxx.xxx' (ECDSA) to the list of known hosts.

ssh_packet_read: Connection closed

```
