Please help, error after upgrading from rc0 to rc2

Hello, After upgrading and running the app I get a black screen and the following error in the console:

It looks like something went wrong in the build process, but it wont error at all.
Any help will be greatly appreciated !

I would try to delete your node_modules folder and run another npm install. Make sure you have the current ionic build too.

Hi, this is a clean install straight from git, What do you mean by check i have the current Ionic build?
I’m using the latest packages:


What’s $ionic info return?

c:\devl\work\wit_mobile>ionic info

Your system information:

ordova CLI: 6.4.0

Try without the carets like ionic2-app-base.

Hi, tried it, deleted my nodeModules, changed and installed, no change…,

I have this same issue here.



add declarations.d.ts to src/

Hi, I already had this file, it came with ionic seed.

Check you’re on latest CLI:

npm install ionic@latest -g

Then build using ‘ionic build browser’ as ionic serve sometime doesn’t flag build errors. If that works, your good. Notice that originally you had the old angular-cli installed but presume thats now updated (run npm install just to be sure)

I had this exact issue with projects freshly-generated from the examples, and posted here. It seems to be resolved, now - my solution was to run:

npm uninstall -g ionic cordova

I then cleared the npm-cache directory (same location as the npm directory, that’s Roaming appdata for me on windows) and my temporary directory before reinstalling both and running ionic start again. I don’t know how an existing project will go down, but I think it should just work.

Edit: It was working, but only briefly - seemingly randomly the same issue has happened.

I finally got a solution to this problem after reading this

  1. I changed the scripts in my package.json file to look like this:

    "scripts": {
       "build": "ionic-app-scripts build",
       "watch": "ionic-app-scripts watch"
  2. I ran npm run build and then ionic serve

And all errors gone

thants, I have the same problem. and fied it by this way!!
