Problem with the dependency of latest @babel/runtime helpers

[hijiangtao]

I met a problem when I install and use deck.gl I traced the error and found it's a problem of viewport-mercator-project's dependency.

The error shows as below:

Module not found: 
Can't resolve '@babel/runtime/helpers/esm/assertThisInitialized' in
'/site/node_modules/[email protected]@viewport-mercator-project/dist/esm'

The package's version is 5.3.0.

Install deck.gl in your project with npm install deck.gl(first time, or use @latest tag when install the package) and run any code that includes deck.gl can reproduce the problem, here is my code:

import React, { Component } from 'react';
import DeckGL, {LineLayer} from 'deck.gl';

class SpatioTemporalMap extends Component {
  render() {
    const viewState = {
      longitude: -122.41669,
      latitude: 37.7853,
      zoom: 13,
      pitch: 0,
      bearing: 0,
    };

    const data = [{sourcePosition: [-122.41669, 37.7853], targetPosition: [-122.41669, 37.781]}];

    const layers = [
      new LineLayer({id: 'line-layer', data}),
    ];

    return (
      <DeckGL viewState={viewState} layers={layers} />
    );
  }
}
  
export default SpatioTemporalMap;

There is a similar problem in luma.gl visgl/luma.gl#805 , and I don't know if there is any other dependency of deck.gl exists the same problem.

I thought downgrade the version of related dependencies should work.

It seems @babel/runtime renamed es6 to esm and caused the can't find module problem. See more at babel/babel#8266 (comment) .

Because of the repo I developed itself can't modify its' babel version casually (@babel/runtime before v7.0.0-beta56)， currently I can only copy the folder in @babel/runtime/helpers/es6 to @babel/runtime/helpers/esm and solve the problem temporarily.

@hijiangtao Which version is specified in your project? Is it exact or with caret?

@TrySound Also see discussion in visgl/luma.gl#805.

@TrySound I specified the version to v7.0.0-beta46 and I thought I found the reason of it. More details can be found in the discussion visgl/luma.gl#805 (comment) .

And I think the issue can be closed, since that's not an internal problem of viewport-mercator-project or other deck.gl related dependencies.
