Trying to get ionic conference app (https://github.com/driftyco/ionic-conference-app) working. ionic 2.1.13 npm version: 3.10.8 node version: 6.9.1 cordova version: 6.4.0

ionic serve -l results in the following output:

ionic-conference-app@ ionic:serve C:\data\app\mkb

ionic-app-scripts serve "-l"

There was an error serving your Ionic application: There was an error with the spawned command: serve

Any ideas as to what has gone wrong?

Many thanks

I've just tried it and it was working for me. On the package.json, it's showing that it's using the latest rc3 ("ionic-angular": "2.0.0-rc.3-201611211919") so try to do the following:

  1. Update your ionic CLI: npm install -g ionic
  2. Delete your node folder and do again npm install
  3. Now, what do you get with ionic serve ?

the error you get is

listen EADDRINUSE 0.0.0.0:8100

looks like the port 8100 is in use. try running on a different port using

--port=8101

also you can change this value in the run.js file

The error suggests to me that the port is in use already.

In my case I closed my browser instances connected to my Ionic app and also closed down my other VS Code Ionic projects and tried running the ionic serve command again and this appeared to resolve the problem.
