Ionic-cli: "ionic serve" fails if there are no external network interfaces

[antoine29]

Hi guys
i'm new with developing ionic apps and i got this trouble when disconnect the internet from my pc

Description:

1. If i have a internet connection (wi fi) i can run "ionic serve" without problems
2. When i disconnect the wifi and i try run "ionic serve" i got this error message
   "Error: It appears that you do not have any external network interfaces. In order to use livereload with emulate you will need one."

Steps to Reproduce:

1. Disconnect from wireless
2. try run "ionic serve"

Output:

"Error: It appears that you do not have any external network interfaces. In order to use livereload with emulate you will need one."

My ionic info:

$ ionic info
cli packages: (/usr/lib/node_modules)
@ionic/cli-utils : 1.9.2
ionic (Ionic CLI) : 3.9.2
local packages:
@ionic/app-scripts : 2.1.3
Ionic Framework : ionic-angular 3.6.0
System:
Node : v6.11.2
npm : 3.10.10
OS : Linux 4.9

Why is this closed?
If all it is is livereload, I should be able to run with --nolivereload and it should work but it does not.

What do I do if I want to develop offline ??

It's not closed... I will be fixing it for 3.10.0 as the milestone states.

This is still an issue, can we get an update on this?

@hornbd96 Can you elaborate? Need ionic serve output and ionic info output.

Here's the ionic serve output in terminal when no internet connection.

events.js:183
throw er; // Unhandled 'error' event
^
