Package build error on Pro: Cannot find module '@ionic/ng-toolkit/package'


I have a package build setup on Pro for a very simple test app. In the build log there are two errors:

[ERROR] Error loading @ionic/schematics-angular package.json: Error: Cannot find module ‘@ionic/schematics-angular/package’
[ERROR] Error loading @ionic/ng-toolkit package.json: Error: Cannot find module ‘@ionic/ng-toolkit/package’

I searched the whole project folder and did not find any “ng-toolkit”. And from npm I know this package is deprecated and is changed to @ionic/angular-toolkit.

I suspect this caused the issue that when I tested my app to access fingerprint or camera on my iPhone 6, it always showed an error of cordova_not_available.

Also the log shows that it’s using quite old version of NodeJS and npm.


I think that ng-toolkit as been deprecated in favor of angular-toolkit (I guess you have a Ionic Angular app)

That’s maybe the problem?

Try the following: create on the side a dummy app (ionic start --type=angular) and then compare your libs with the current state of the libs aka compare your package.json with the dummy package.json, maybe you will find that difference. There “force” a clean install in your project (remove package-lock and node_modules and install again)


Thanks @reedirichards for your reply. Yes it’s a Ionic 4 Angular app and I have tried what you have suggested but it’s still the same.

Submitted a Ionic Pro support form 3 days ago and received an email with following texts:

“…The Ionic offices are currently closed for the Labor Day holiday. We will reopen at 9:00 AM CDT(UTC -5) on Tuesday, September 4th. …”


could you display your package.json plz

have you removed package-lock and node_modules and reinstalled everything?
what’s the error now? can’t be ng-toolkit anymore since you don’t reference it


Yes did that exactly. I suspect there is something wrong with the pro build environment. Here is the screenshot of the build log:


effectively something weird if it compiles correctly locally but doesn’t remotely


I am trying to set up a local Mac OS environment to see what happens. If it proves it’s the Ionic Pro build environment then I don’t see why I should keep my Ionic Pro paid service.


let me know what happens locally

why jumping to such a conclusion? you contacted the support, they gonna answer after their holidays


@reedrichards Not sure if you have read my post carefully, it says it will reopen on September 4th… lol


Lol yep that’s a while ago :wink:


To which email did you write?


@reedrichards, I have set up a virtualbox with Mac OS, and can confirm it built successfully without the ng-toolkit error.

Are you able to help to look at two issues with the Pro build environment?

  • @ionic/ng-toolkit error
  • NodeJS is an old version



Unfortunately can’t help more, I don’t use pro


Sorry I thought you are from Ionic. Thanks for trying to help.


Haha no at all :wink:

You didn’t answered my last question, from curiosity, to which support email address did you write to? maybe its just inactive and they are using a new one?
