the ECDSA host key for 'github.com' differs from the key for the IP address

今天克隆项目之后，重新安装npm依赖包报错如下：
```
npm ERR! code 128
npm ERR! An unknown git error occurred
npm ERR! command git --no-replace-objects ls-remote ssh://git@github.com/angular/web-animations-js.git

```

网上搜索一下，原来是git证书过期了，需要删除重新添加一下

```
ssh-keygen -R 20.205.243.166
ssh-keyscan github.com >> ~/.ssh/known_hosts
```
