Error: Unexpected value 'Ng2DragDropModule' imported by the module

Also if I console Ng2DragDropModule just before @NgModule annotation I can see:

function Ng2DragDropModule() {}

@gund , I think this is probably related to using webpack. I haven't tested or added support for webpack yet. (I plan to). If could possibly provide me a plunkr that would really help.

[gund]

@ObaidUrRehman I'm not sure it is possible to use webpack with plunkr =)

Anyway there is really no configuration required for webpack to use your library, I just npm install it and import that should do the job.
But for some reason angular complains.

You can try to create project with angular cli, install your lib and import it to AppModule to see that error in runtime.

@gund what version of ng-cli are you using? Its seems that this is a know problem with older versions of cli. See Also: videogular/videogular2#249

I encountered the same problem with angular-cli 1.0.0-beta-15.0.0 but with v 1.0.0-beta.19-3 its working fine.

[gund]

I do use angular-cli v1.0.0-beta-16 so I will try to upgrade it and try again.
Thanks for referencing an issue.

[gund]

You are right with updated angular-cli (1.0.0-beta.19-3) this is not longer an issue.

Thanks a lot!

fyi - i'm having the same error, using the latest greatest angular-cli (1.0.0-beta.24) with angular 2.3.0. i happen to be using webpack, so not sure if that is a factor after all as suggested above. i tried rolling back to angular-cli 1.0.0-beta.19-3 since that was the apparent solution above, but that didn't resolve the matter for me. suggest we keep this issue open. if i find a solution i'll post.

@sarora2073 can you tell if you are getting that error in AOT mode only?

[sarora2073]

No, i'm not doing this in AOT mode.

[ObaidUrRehman]

This seems to be an issue with angular-cli.
For refrence: angular/angular-cli#3426

I need to look into this in detail.

@sarora2073 I just updated ng2-drag-drop to v0.5.1. Now using ngc to build instead of tsc (among other changes). Its now working on angular-cli v1.0.0-beta.24
