Angular 5

I have followed your instruction and I am trying to implement on Angular 5.
But there is a strange thing that when using ng server everything works fine, but when I am building for production I am getting

main.d32a5818ac6f3d928ac5.bundle.js:1 ERROR Error: Formatter or Parser with name currencyFormat
is not provided as a function via FormatterParser
service or FORMATTER_PARSER InjectionToken.
Did you forgot to provide them?
at n.getFormatParseFunction (main.d32a5818ac6f3d928ac5.bundle.js:1)

Has anyone else found a similar problem with angular 5?

Reproduce the difference between `ng server` and the Angular 5 production build, then inspect the production bundle around the FormatterParser error. Trace why `currencyFormat` is not provided as a function or injection token and confirm the fix by rebuilding for production without the error.
