Error:

 Cannot determine the module for class ImageViewerComponent in
            C:/project/node_modules/ionic-img-viewer/dist/umd/src/image-viewer.component.d.ts! Add
            ImageViewerComponent to the NgModule to fix it.

Thats occur only when I try to build with --prod

Did you guys get any solution for this problem? As i am also facing the same issue while compiling for Android

[telran]

I have the same problem, is there a solution for this?

[vidyachilukuri]

Same issue for me also, without --prod its working fine, but for --prod I'm getting Metadata version mismatch for module/node_modules/ionic-img-viewer/dist/es2015/src/module.d.ts, found version 4, expected 3

Hey, it seems that you are not using the right version of the ionic-img-viewer package for you angular version.
Try npm install ionic-img-viewer@latest --save

[anytimegorgeous]

Same error. Updating package does not help

[Riron]

What's your angular version ? It's probably the other way around in fact, if you have found version 4, expected 3 you should use a lower version. I guess you are using Angular 4.x ?

Hi this error is generated at compilation!
./node_modules/ionic-img-viewer/dist/es2015/src/image-viewer-impl.js
Module not found: Error: Can't resolve 'ionic-angular' in 'D:\Mes Projets Ionic\mdc\node_modules\ionic-img-viewer\dist\es2015\src'

Already in my PROBLEMS console I get
{
"resource": "/d:/Mes Projets Ionic/mdc/node_modules/ionic-img-viewer/tsconfig.json",
"owner": "typescript",
"severity": 8,
"message": "File 'd:/Mes Projets Ionic/mdc/node_modules/ionic-img-viewer/ionic-img-viewer.ts' not found.",
"source": "ts",
"startLineNumber": 1,
"startColumn": 1,
"endLineNumber": 1,
