bee run 输出中 没有 localhost 什么原因

bee run 输出如下 ``` 2018/09/22 19:01:21 SUCCESS ▶ 0003 Built Successfully! 2018/09/22 19:01:21 INFO ▶ 0004 Restarting 'huliuhe.exe'... 2018/09/22 19:01:21 SUCCESS ▶ 0005 './xxx.exe' is running... 2018/09/22 19:01:21.808 [I] [asm_amd64.s:2361] http server Running on http://:8080 ``` 为什么不是 localhost:8080 其它正常, 127.0.0.1:8080 能访问.
