I have similar problem.. but only when I use "ng build --prod"

RROR in : Unexpected value 'Ng2Permission in ...../node_modules/angular2-permission/dist/module/ng2-permission.module.d.ts' imported by the module 'AppModule in ..../src/app/app.module.ts'. Please add a @NgModule annotation.

w/out the --prod flag is working correctly.

Any ideas ?

Actually it seems to be related to AOT flag, if it is set to false the build is OK...
