Error running ionic serve


My npm is version 3.88

My Nodejs version is v6.0.0

I have just installed npm install -g ionic@beta as of 4/28/2016.

This is my package.json file:

  "dependencies": {
    "angular2": "2.0.0-beta.15",
    "es6-promise": "3.0.2",
    "es6-shim": "^0.35.0",
    "ionic-angular": "2.0.0-beta.6",
    "ionic-native": "^1.1.0",
    "ionicons": "3.0.0-alpha.3",
    "reflect-metadata": "0.1.2",
    "rxjs": "5.0.0-beta.2",
    "zone.js": "0.6.11"
  "devDependencies": {

    "run-sequence": "1.1.5"
  "name": "ionic2_gae",
  "description": "ionic2_gae: An Ionic project",
  "cordovaPlugins": [
  "cordovaPlatforms": [

When I run ionic serve I get the following error:

(node:11980) fs: re-evaluating native module sources is not supported. If you are using the graceful-fs module, please update it to a more recent version.
There is an error in your gulpfile:
Error: Node Sass does not yet support your current environment: Windows 64-bit with false

How can I get this running?


I believe you need to downgrade your node version as Node SASS is not currently up-to-date with Node v6


@polska03 Most probably because of Node v6 as @Mobius77 suggested, more details here:


Yep indeed node version was problem. Thank you
