                           ~~~~~~~~~~~~~~~

please resolve

Closing that. Here is a repo where auto-linked @date-io/type module works like a charm

yarn tsc succed

For me the missing type was added after configuring the locale

import { MuiPickersUtilsProvider } from '@material-ui/pickers';
import MomentUtils from '@date-io/moment';
import moment from 'moment';
import 'moment/locale/pl';

moment.locale('pl');
...
      <MuiPickersUtilsProvider utils={MomentUtils} locale="pl">
...

The missing type comes with @date-io/moment

For Clarity: The package is the only thing in the repo. No Im not using yarn

Closing due to silency

thats one of the first things i tried actually… ! Right now as a temporarily “fix” i added "skipLibCheck": true, to my tsconfig file because we are using it in a project that we use at my company and we need build to pass 😄 But i’m going to look into it today or tomorrow for an alternative) because i do not want to have this options set !

Here is https://github.com/dmtrKovalenko/date-io/tree/master/packages/date-fns/type

Actually one thing you need is to make

declare module "@date-io/type" {
  export type DateType = Date;
}

Further details are here: https://github.com/dmtrKovalenko/date-io/issues/52

Though I’ve still not been able to solve it. Ideas are welcome.

@dmtrKovalenko I am seeing the same thing with @date-io/date-fns@1.3.7 and there is no @date-io/lib installed locally (mentioned in https://github.com/mui-org/material-ui-pickers/issues/1074#issuecomment-497763923)

As far as I can tell, the only occurrence I have of this is in node_modules/@date-io/date-fns/type as a manual type declaration or augmentation.

I’m now confused. Where is the source of @date-io/type and why is it referred to as a package when it is neither published nor installed as such?
