Webpack build issue with tns-platform-declarations

[kvindascr]

When installed tns-platform-declarations, webpack generate the following error:

Try deleting the platforms folder. From the provided log, I understand you are building for android. Also which versions of typescipt and @ngtools do you use?

Hello,

Sis0k0, I was really building IOS.
In fact I needed to delete android platform at somepoint because for some reason Android issues were getting in between when building IOS.

Regarding versions they are:

• Typescript: 2.0.10
• ngtools?? What exactly do you mean by ng-tools. I looked out in my node_modules but I have no package starting with ng-, not anyone of the described in your link.

Thanks.

You should have a dev dependancy of @ngtools/webpack if you are using the nativescript-dev-webpack plugin. Also try deleting the whole platforms folder and rebuild with npm run build-ios-bundle. Hope that helps! If it does not, please send us a project where you can reproduce the error.

I usually see this error if I have run a non-webpack tns prepare/run/build/debug ... before I run the webpack command. Usually I run tns platform remove ... for both Android and iOS. Strangely, you need to remove it for both, so if I have run and Android build only, and then do an iOS webpack, the iOS webpack will fail and vice-versa.

I don't believe it's related to the tns-platform-declarations, as I had those included in the project before and this issue only popped up with one of the updates a few weeks back.

All my dependencies are up to date with the latest versions ( including all the angular/webpack/nativescript packages, etc. ) with the exception of:
rxjs: 5.0.3
typescript: 2.1.6

I got rid of this error by removing platforms and not executing the "run" command before bundling. Weird.
@DickSmith Thanks!

This is quite annoying. When I debugged it, it's clearly related to the tns-platform-declarations missing in the platforms. (The same file as the OP has)

I suspect this is some hook malfunctioning?

[ishitatsuyuki]

The suspicious folder is platforms/android/src/main/assets/app/tns_modules. Maybe they are not cleaned across builds?
