Error: Unexpected value 'NouisliderModule in ...

When I am building my project for production the following error is appearing.

Error: Unexpected value 'NouisliderModule in /path-to-project/node_modules/ng2-nouislider/src/nouislider.js' imported by the module 'MyModule in /path-to-project/src/my.module.ts'. Please add a @NgModule annotation.

Has anyone a tip for me? I don’t know why this error occurs.

I changed

import {NouisliderModule} from 'ng2-nouislider';

to

import {NouisliderModule} from 'ng2-nouislider/src/nouislider';

and now it is working… But this is not a nice solution. I think there should be added an index.ts that has a reference to the src/nouislider directory.

@iCodr8 This workaround is indeed working. Thank you for that! At least I can continue development until there is an actual fix to the issue.

This seems to be the culprit: https://github.com/tb/ng2-nouislider/issues/113
