git 出现错误 Could not resolve host:

原来是因为github.com没有被主机给解析，

第一步 ping github.com

PING github.com (192.30.255.112): 56 data bytes

64 bytes from 192.30.255.112: icmp_seq=0 ttl=43 time=144.449 ms

64 bytes from 192.30.255.112: icmp_seq=1 ttl=43 time=140.965 ms

^C

--- github.com ping statistics ---

2 packets transmitted, 2 packets received, 0.0% packet loss

round-trip min/avg/max/stddev = 140.965/142.707/144.449/1.742 ms

先 ping 看一下主机地址

然后 编辑文件etc/hosts

sudo vi /etc/hosts

i  启动编辑模式

::1             localhost

192.30.255.112  github.com

然后添加github的地址

esc 退出编辑模式

:wq退出vi
