I'm receiving the same error:
Error:Error:line (15)TS2693: 'LocaleUtils' only refers to a type, but is being used as a value here.

Seems to occurr because LocaleUtils is exported as an interface and not as a const like DateUtils and ModifiersUtils in react-day-picker?

Was this issue not resolved by this? gpbl/react-day-picker#834

[mprotasov]

I used to fix problem with Error:Error:line (15)TS2693: 'LocaleUtils' only refers to a type, but is being used as a value here. It was fixed in version 7.3.2 of react-day-picker, then broken in version 7.4.0, then again fixed in current unreleased master.

I changed my package-lock.jsonin following way:

1. Remove "react-day-picker": "^7.3.2" from "requires" section
2. Add "react-day-picker": { "version": "7.3.2" }
   to "dependencies" section (force datetime to use specific version of lib)
3. Delete node_modules dir and rerun npm install

It is temporary fix, the problem should be fixed after release of new version of react-day-picker.

Hope this helps

I have the same issue, as this is fixed on master - would it be possible to release the fix? That would be awesome.
