Unexpected value 'NgCytoscapeModule' imported by the module 'AppModule'

[troelssiggaard]

I'm having trouble importing Ng2-Cytoscape. When I compile it gives this error:

ERROR in NgCytoscapeModule is not an NgModule
webpack: Failed to compile.

I'm using the latest Angular 4.4.0-RC.0.

Check #6, as far as I know it might not work because ng2-cytoscape uses angular ^4.3.5, since you use ^4.4.0-RC.0.

[troelssiggaard]

Well, I just downgraded to ^4.3.5 without any changes, the error persists. :(

[ssuperczynski]

Have you tried rm -rf node_modules?
Could you add whole stack trace here.
Could you try import {NgCytoscapeModule} from "ng2-cytoscape"; instead of import {NgCytoscapeModule} from "ng2-cytoscape/dist";

I was seeing this problem when using 4.4.0-RC.0. I have tested this with the newer version of Angular (4.4.3), this is no longer an issue.
