Unable to GET // __ ion-dev-server / ionic_lab.html in ionic version 2.1.8

Question

I updated local settings like

• ionic
• Cordova
• NPM
  See System Environment Available on My Machine -

---

******************************************************

Your system information:

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: 5.0.8 
OS: OS X Yosemite
Node Version: v6.2.2
Xcode version: Xcode 7.2 Build version 7C68



******************************************************

after that I started the server by typing -

ion start

It works, but displays only one view in the browser instead of three (android, ios and windows).
When I use another command to get all as-

ion feed -lab (or) ion feed -l

It just shows the error in the browser as -

Unable to GET // __ ion-dev-server / ionic_lab.html

I had questions there in the ion forum , but this will not work for me, as there was no answer.

We hope for help !!!
