I'm getting following error when I build the Angular app using "ng build --prod". This is working when I build with Angular 4 and getting error with Angular 5. With Angular 5 "ng serve" is working perfectly.

ERROR in Error: Cannot determine the module for class TimeAgoPipe in mypath/node_modules/time-ago-pipe/time-ago-pipe.ts! Add TimeAgoPipe to the NgModule to fix it.

Getting error for https://www.npmjs.com/package/time-ago-pipe

Any solutions ?

Check Case Sensitivity

import { MyComponent } from "./User/my-component";

In my case, the problem was that the folder user was created with U as capital in my import statement. But actually on disk it was in small case. When I renamed the folder to user (with u lower case) in my import statement also, it worked for me. 

import { MyComponent } from "./user/my-component";

So check the case sensitivity, of your import path.
