Ionic-cli: ionic serve -l is broken

[adjhernandez]

System Info

Cordova CLI: 6.4.0
Ionic Framework Version: 2.0.0-rc.2
Ionic CLI Version: 2.1.8
Ionic App Lib Version: 2.1.4
Ionic App Scripts Version: 0.0.43
ios-deploy version: Not installed
ios-sim version: 5.0.11
OS: OS X El Capitan
Node Version: v7.1.0
Xcode version: Xcode 8.0 Build version 8A218a

When running ionic serve --lab from the terminal this is the output:

ionic-hello-world@ ionic:serve /Users/aaronhernandez/Documents/IonicProjects/simpletabtest
ionic-app-scripts serve "--lab"

[18:16:43] ionic-app-scripts 0.0.43

[18:16:49] watch ready in 5.53 s
[18:16:49] dev server running: http://localhost:8100/

When the browser launches it tries to go here:
http://localhost:8100//__ion-dev-server/ionic_lab.html

Displayed on the page is:
Cannot GET //__ion-dev-server/ionic_lab.html

Not sure what's happening here. I can still emulate either platform and deploy to devices fine but the lab just simply doesn't work. As an alternative I can launch the lab from the "Ionic Lab" desktop app and it works fine.

Please verify your package.json

https://github.com/driftyco/ionic-app-scripts

"scripts": {
"build": "ionic-app-scripts build",
"watch": "ionic-app-scripts watch"
},

Remove "ionic-build"

[gtejwani]

package.json and remove "ionic:serve"

"scripts": { "ionic:build": "ionic-app-scripts build", "ionic:serve": "ionic-app-scripts serve" },

Remove "ionic:serve"

"scripts": { "ionic:build": "ionic-app-scripts build" },

Thanks for the issue! This issue appears to be associated with an old version of the Ionic CLI. Please update to the latest CLI version, which supports all versions of the Ionic Framework. If the issue is relevant and if it persists after updating to the latest CLI version, please create a new issue.

Thank you for using Ionic!
