Production build with AoT throws error - Error encountered resolving symbol values statically

[naveedahmed1]

When trying production build with AoT in Angular CLI, it throws the below error:

ERROR in Error encountered resolving symbol values statically. Calling function 'makeDecorator', function calls are not supported. Consider replacing the function or lambda with a reference to an exported function, resolving symbol NgModule in /node_modules/ic-datepicker/node_modules/@angular/core/src/metadata/ng_module.d.ts, resolving symbol NgModule in /node_modules/ic-datepicker/node_modules/@angular/core/src/metadata.d.ts, resolving symbol NgModule in /node_modules/ic-datepicker/node_modules/@angular/core/src/core.d.ts, resolving symbol NgModule in /node_modules/ic-datepicker/node_modules/@angular/core/index.d.ts, resolving symbol IcDatepickerModule in /node_modules/ic-datepicker/dist/src/ic-datepicker.module.d.ts, resolving symbol IcDatepickerModule in /node_modules/ic-datepicker/dist/src/ic-datepicker.module.d.ts

ERROR in ./src/main.ts
Module not found: Error: Can't resolve './$$_gendir/app/app.module.ngfactory' in '\src'
 @ ./src/main.ts 4:0-74
 @ multi ./src/main.ts

I have imported the IcDatepickerModule module like this in my module:

import { IcDatepickerModule } from 'ic-datepicker/dist';

If I update the import to the following:

import { IcDatepickerModule } from 'ic-datepicker';

and delete all contents of node_modules\ic-datepicker
and then copy paste the contents of node_modules\ic-datepicker\dist in node_modules\ic-datepicker. It works. Can you please have a look?

I'm looking into the build issues now but it's going to take some research from my side - is this not a duplicate of #3?

Yes indeed, I am sorry I just realized.
