SyntaxError: Unexpected token 'export'

[ali-heidari]

Describe the bug

It seems there is a problem with exporting different versions inside of uuid. My project is using uuidv4 which is using uuid.

To Reproduce

Steps to reproduce the behavior:

1. Install 'uuidv4'
2. Run project (commonJs style)
3. See error

Expected behavior

Expected to run without problem.

Runtime

• OS: Win10
• Runtime: Node.js
• Runtime Version: 14.3.0

Additional context

You can see the error here:

...\node_modules\uuidv4\node_modules\uuid\dist\esm-browser\index.js:1
export { default as v1 } from './v1.js';
^^^^^^

SyntaxError: Unexpected token 'export'

[TrySound]

This point is not clear. Is it node project or some bundler, which bundler?

Run project (commonJs style)

[ali-heidari]

It is node project... I guess it happens because of my node written in commonJs and uuid is es6!

[TrySound]

Nope. UUID is distributed as commonjs by default.
https://unpkg.com/browse/uuid@8.2.0/dist/index.js

How do you import uuid? And provide please minimal reproduction.

[ali-heidari]

But my console shows an error

node_modules\uuidv4\node_modules\uuid\dist\esm-browser\index.js:1
    export { default as v1 } from './v1.js';
    ^^^^^^

    SyntaxError: Unexpected token 'export'
        at compileFunction (<anonymous>)
        at wrapSafe (internal/modules/cjs/loader.js:1116:16)
        at Module._compile (internal/modules/cjs/loader.js:1164:27)

which pointed to this file:

export { default as v1 } from './v1.js';
export { default as v3 } from './v3.js';
export { default as v4 } from './v4.js';
export { default as v5 } from './v5.js';

What am i missing here?
what is the root of problem ? uuidv4? uuid? esm-browser????

[TrySound]

Show how do you import uuid, give us a reproduction.

[ali-heidari]

This is how i import:

const { uuid } = require('uuidv4');

[TrySound]

This package?
https://www.npmjs.com/package/uuidv4

[TrySound]

The wrong one. Please read documentation.

[TrySound]

I see. This package is the dependency of your one. Could you switch to using uuid package directly?

[ctavan]

Closing since this seems to be related to a reverse dependency of this package. Please open a bug report in the appropriate issue tracker if the problem persists: https://github.com/thenativeweb/uuidv4/

[riccardoNovaglia]

Hey folks, I think this still might be an issue, getting exactly the same problem, importing uuid directly.

Made a repo here to show the problem.

Versions:

➜  tmp git:(master) node --version
v13.2.0
➜  tmp git:(master) npm --version
6.14.7

Hope it helps

[ctavan]

@riccardoNovaglia your node version has incomplete support for the package.exports feature. It's also not actively supported by Node.js anymore, see https://nodejs.org/en/about/releases/

Please upgrade to Node.js v14 if you want to use ESM or downgrade to v12 if you want to use CommonJS.

[riccardoNovaglia]

@ctavan absolutely right. Can confirm it works with both v12 and v14. Thanks for the help!

[asitbiswas]

update your node. i had the same problem using node 13.3.0 and uuid 8.3.0.

then i upgraded to node 14.12.0 and it worked

[RatonBiswas]

const { v4 : uuidv4 } = require('uuid');

export { default as v1 } from './v1.js';
^^^^^^
SyntaxError: Unexpected token 'export'

How can I solve this?

[TrySound]

@RatonBiswas Why do you mix commonjs and es modules? uuid supports both. And what is your environment? We cannot help without additional information.

[RatonBiswas]

update your node. i had the same problem using node 13.3.0 and uuid 8.3.0.

then i upgraded to node 14.12.0 and it worked

yes, you are right.

[fatihyenidunya]

if it is still not running after updated node, try update uuid npm install uuid

[guillefix]

I still have this issue
