Error: Can't resolve './data/fr.js'

[spras]

I Try to use the format-currency-precise filter

I Begin without Loading FormatJS Data , but run in a [Vue warn]: Error in render function: "TypeError: _vm._f(...) is not a function" error

Then I try to loading FormatJS Data :

import IntlRelativeFormat from 'intl-relativeformat'
import relativeFr from './data/fr.js'
IntlRelativeFormat.__addLocaleData(relativeFr)

But of course i run in a Module not found: Error: Can't resolve './data/fr.js' error. Where can i found the data/fr.js ?

Thank's for your help
