Error: cannot find module @date-io/core/IUtils

[nzacca]

Hello!

Nice refactor! I'm encountering the following error after updating.

ERROR in /<truncated>/node_modules/@date-io/moment/build/moment-utils.d.ts(2,24):
TS2307: Cannot find module '@date-io/core/IUtils'.
ERROR in /<truncated>/node_modules/material-ui-pickers/_shared/BasePicker.d.ts(1,24):
TS2307: Cannot find module '@date-io/core/IUtils'.
ERROR in /<truncated>/node_modules/material-ui-pickers/_shared/WithUtils.d.ts(1,24):
TS2307: Cannot find module '@date-io/core/IUtils'.

I was able to workaround the issue by manually installing the core package but I was wondering if perhaps it should be included as a dependency of the moment/date-fns/etc. packages instead?

This is where the problem is (which goes away after installing core):

@nzacca you are using typescript?

[nzacca]

@dmtrKovalenko Yes. v3.1.6

I have the same problem with TS

[dmtrKovalenko]

Published in v0.0.2 with the fix

@dmtrKovalenko this issue came back in v1.2.0

Issue was introduced here: e0dfb67#diff-3c70df024fb0ca5df014877fa49bcc08L12

May be able to use a type import (ex. import("@date-io/core").IUtils) instead since it is only used to grab the IUtils type def.
