When using import in any .js file

[AlexiRJamal]

Node version: v8.11.1

When using const something = require('lib) everything works fine. But when using import something from 'lib' it shows this:

SyntaxError: Unexpected token import
    at createScript (vm.js:80:10)
    at Object.runInThisContext (vm.js:139:10)
    at Module._compile (module.js:616:28)
    at Object.Module._extensions..js (module.js:663:10)
    at Module.load (module.js:565:32)
    at tryModuleLoad (module.js:505:12)
    at Function.Module._load (module.js:497:3)
    at Function.Module.runMain (module.js:693:10)
    at startup (bootstrap_node.js:188:16)
    at bootstrap_node.js:609:3

I don't know what's wrong, or if I'm doing anything wrong :/
Thanks anyways for any help :)

Basically, when using any ES6 syntax. I tried using 'use strict' but it didn't work.

Make sure that

• Node.js is started using --experimental-modules flag
• Script extension is .mjs

Example: node --experimental-modules script.mjs

another way to use import/export is that install @babel/core and @babel/node

https://babeljs.io/docs/en/babel-node

after adding to your dependencies or devDependencies (I support to second) then run babel-node index.js

That was part of the problem. My extensions were .js only.

Thanks man.

I have babel code installed as global. Dunno why it raised this error in the first place. Ironically when working with React it doesn't happen at all :/

react using webpack with other babel parts to transfer code, babel-node just the lib that is easy to run in time

I think you used it in the wrong way

Do I need to require the babel-node too or...?

Hey @loox37
Was the issue solved?

[GrosSacASac]

Having babel installed will not make Node use babel automatically. You need to be explicit.
babel-node should not be required inside the code. Instead It is a drop in replacement for the node command. So instead of
node index.js
do
npx @babel/node index.js
assuming it is in devDependencies

Thanks for all of you.
The issue was resolved by using babel, I forgot to close this question.
I'm not one of these guys who say "solved, thank you" without leaving the answer:
Install babel
If necessary, do npm link
Then use import.

Thank you!!
