Mac OS Ping：Ping必须以root用户身份运行

Question

在 mac os 10.13.6 iterm3终端

中

➜ ping baidu.com 
ping: ping must run as root

但何时：

➜ sudo ping baidu.com   
PING baidu.com (220.181.57.216): 48 data bytes   
56 bytes from 220.181.57.216: icmp_seq=0 ttl=54 time=59.912 ms   
56 bytes from 220.181.57.216: icmp_seq=1 ttl=54 time=48.389 ms

没关系。

添加到您的zshrc
