终于解决了.如果您使用本地 DNS 服务器，请将以下内容添加到您的主机中.

Finally Solved. Add the following to your hosts if you use a local DNS server.

::1 localhost
127.0.0.1 localhost
255.255.255.255 broadcasthost
fe80::1%lo0 localhost

引用答案:

用户可以通过更改 DNS 服务器来解决问题本地一个(由接入点提供)到 Google DNS 服务器(8.8.8.8).

User was able to fix the problem by changing the DNS server from the local one (provided by the access point) to Google DNS server (8.8.8.8).

它看起来像 Mac OS Lion 和更高版本不首先使用/etc/hosts 文件，优先考虑 DNS 服务器，因此 localhost 可能没有解决(虽然，目前还不清楚为什么它不回落到/etc/hosts).

It looks like Mac OS Lion and later doesn't use /etc/hosts file first, giving priority to DNS servers, hence it's possible that localhost may not resolve (though, it's unclear why it doesn't fall back to /etc/hosts).
