如何正确导入草坪模块

Question

This should be straigh forward.

yarn add turf

and then - according to documentation :

// Import your module of interest
var collect = require('@turf/collect');
// or in ES6
import collect from '@turf/collect';

But, when I try any of these, it does not work. I get

Unable to resolve module @turf/collect .

When I check the node_modules folder, I see that turf installed properly (at least there are folders and there is something in them).

I tried this in a react-native project:

1. watchman watch-del-all
2. Delete node_modules and freshly yarn install
3. Reset Metro's cache with yarn start --reset-cache

Answer 1

I was led to this question for a related problem.

To import a specfic module with a name that is more than one word it becomes camel case like so:

import nearestPointOnLine from '@turf/nearest-point-on-line';
import booleanPointInPolygon from '@turf/boolean-point-in-polygon';

Answer 2

The namespace changed. Turf must be installed with @turf/turf , ie yarn add @turf/turf
