[Question] Required module not found

[raduchiriac]

EDIT: I am using yarn workspaces and lerna
Probably not a real issue but I am getting flow-geojson. Required module not found when using this.

import type {
  Point2D,
  MultiPoint2D,
  LineString2D,
  MultiLineString2D,
  Polygon2D,
  MultiPolygon2D,
} from 'flow-geojson';

Following this did not help:

Because I now get
Type annotations require valid Flow declaration flowtype/no-types-missing-file-annotation

Thanks for report. I review it in next 4 hours.

@raduchiriac thanks for report, but it just works. =)

Please read about this Flow ESLint plugin rule — no-types-missing-file-annotation. Make sure you have the valid Flow file declaration.

Please tell me about result.

It needed more clarifications from my side as I am actually using yarn workspaces with lerna. (I will edit the original question as well).

I first tried to yarn add inside the subfolder where I needed this package, and since the package will be installed in the root, I am guessing the symlinks are not properly created and I got flow-geojson. Required module not found. Not sure how to debug this case.

The only workaround I found is doing yarn add -W flow-geojson in the root (which is not ideal, I only have jest, eslint, babel in the root) and removing node_modules from my .flowconfig ignore.

Let's leave it closed as it's a very specific case, will come back with more details

If you are using an npm package that supports flow, you should not ignore it.
