Ioinic updated, serve fail, Gulpfile.js can't be found

Ionic Framework ionic-v3
18

Oh, you were on 2.0.0-beta.10 - that changes everything :frowning: :confused: But of course makes sense as it is from Nov 3, 2016.

On the other side now makes sense that stuff didn’t work before and requires a bit more work to get it working.

New plan:

  1. I would checkout this version that you build your app from into a new, clean folder.
  2. Then create a new Ionic project in another folder with ionic start blank blank. (folder will be named “blank” then)
  3. Copy the scripts part of the blank’s package.json to your project’s.
  4. Remove your devDependencies and replace it with this:
"devDependencies": {
  "@ionic/app-scripts": "0.0.47",
  "typescript": "2.0.9"
}

(this is from https://github.com/ionic-team/ionic/releases/tag/v2.0.0-rc.4 which is the closest to you version I could find)
5. Then run ionic info on it. What does it tell you?
6. If no errors, try ionic serve. What does it tell you?
