Problem with default export after update to 2.1.0

[adascal]

Hi, after updating from version 2.0.1 to 2.1.0 I start getting error for code like:

export default from './Map.jsx';

Stack trace:

Node must be provided when reporting error if location is not provided

I was going to open the exact same issue.

[email protected] with [email protected] work fine for me...
Check installed module, maybe it's 2.1.0? :)

[yvele]

@adascal I'm using the exact same versions as you and I'm having the same error with an index.jshaving export foo from "./foo";

[ljharb]

@adascal you're using proposed syntax https://github.com/leebyron/ecmascript-export-default-from - which isn't part of the language, and is only stage 1. Are you using babel-eslint for this?

@yvele export notDefault from 'path' is in the language. export default from 'path' is not, which is what the OP is using.

[yvele]

@ljharb Yep. I'm not using default but I still have the Node must be provided.. error

[ljharb]

Ah, gotcha, thanks for clarifying.

[adascal]

@ljharb, yes, I'm using babel-eslint

[benmosher]

Hmm, I wonder if it's a babel-eslint change... not sure what would get into that situation. Regardless, we've got a bug here. Thanks for reporting!

So … We can use this way:

export { default } from './Map.jsx';

instead

export default from './Map.jsx';

I'm still getting this issue on 2.21.2

@CalebDelbridge can you file a new issue? it'd be great if you also provided your eslint/plugin versions, as well as the code that's causing this to crash.

sometime, this error maybe occured by export enum in ts file, finally I give up use enum to fix the error. but enum is a nice feature，anyone know how to change the lint rule to use enum

@Jinwan5290
try this way

// .eslintrc.js
'no-unused-vars': 'off',
'@typescript-eslint/no-unused-vars': ['warn']
