Importing error with angular 5 prod build

[sukhdevsinghsaggar]

I am importing the module like -

app.module.ts

`import {CountDown} from 'ng4-date-countdown-timer';`
declarations: [
    .. ,
    CountDown
]

While running the ng build --prod command it is giving me the following error -

ERROR in : Unexpected value 'CountDown in /home/jayanth/Documents/Workspace/sozial-front/node_modules/ng4-date-countdown-timer/dist/countdown.d.ts' declared by the module 'AppModule in /home/jayanth/Documents/Workspace/sozial-front/src/app/app.module.ts'. Please add a @Pipe/@Directive/@Component annotation.

Same problem. No solution after more than a year?
