Description:
I installed new ionic cli release, and since i'm unable to run application.
The message stop at "[app-scripts] [09:08:10] lint finished in 1.48 s" and then continue to output "Waiting for connectivity with ionic-app-scripts". If I stop the build with ctrl + c and try to rerun again, i get error :
[app-scripts] Error: listen EADDRINUSE :::53703
[app-scripts] at Object.exports._errnoException (util.js:1020:11)

I get this error until I close the terminal, try to run again, get "Waiting for connectivity", same loop.

Steps to Reproduce:
update ionic cli and run "ionic cordova run android --livereload --address [address]

npm run start is work. and "start": "ionic-app-scripts serve --address 0.0.0.0 --port 8100 --livereload-port 35729 --dev-logger-port 53703 --nobrowser", is work.

@dwieeb await isHostConnectable('localhost', port); can't resolve, when dev server started.
https://github.com/ionic-team/ionic-cli/blob/develop/packages/%40ionic/cli-utils/src/lib/project/ionic-angular/serve.ts#L120

so npm run start is work, and ionic serve seems not work. (but background, work)
Sorry, I could't fix it.

imhoffd commented Jul 30, 2018

@rdlabo That's okay, thanks for finding where the CLI is hanging. isHostConnectable() should resolve when a TCP connection can be made:

ionic-cli/packages/@ionic/cli-framework/src/utils/network.ts

Lines 80 to 85 in 49d9493

const sock = net.connect({ port, host });
sock.on('connect', () => {
sock.destroy();
resolve(true);
});

This code exists so that the Ionic CLI knows when to open the browser window.

There must be something going wrong between hosting a server on 0.0.0.0:8100 and attempting connections via localhost:8100.

Hello,

I'm was using command "ionic cordova run android --livereload --address [address]" with my ip address (192.168.254.58:8100) because i need to test on my mobile so i can't have a "localhost" address.

I tried the code in the commit, the application now build and runs but the livereload doesn't work. when i enter the address in a browser i get "ERR_CONNECTION_REFUSED"

I tried again today and livereload, most of the time, doesn't work and I have to relaunch command several times to make it work again, I tried the fix "fix(cli-utils/project): pass the host address as it is" but it doesn't change the situation, i use either the command "ionic cordova run android --livereload --address [address]" or either using ""ionic cordova run android --livereload" and choose address. It looks pretty random, sometimes it works again

Also getting it for my ionic3 project, only when I give --address parameter ;)

There is an open PR that should fix this issue: #3444

For anyone that tried everything here but it still didn't work:
Try running:
npm run clean
and then
npm run ionic:serve

Worked for me.

@amanitequeen @sebmeg Thanks for confirming the issue is resolved!

@sebmeg Please create new issues for new errors.

@fyayc-chrisat Did you try updating the Ionic CLI to 4.0.3? Multiple people have said the original issue is resolved in this version that was just released. If that is not the case, let me know.

Steps that work for me after installing 4.0.3 ionic version:

  • Delete project complete node modules.
  • npm i -g @ionic/app-scripts --save-dev
  • npm i
  • ionic serve

I am still using Ionic 3, and first time I got this error although I didn't update or install any thing related to nodejs or ionic. All I did was connected my laptop to VPN network. When I turned that VPN off it start working again.
