I keep getting this error message when i try to run my debugger in VSC. Can anyone please help? Here's a screenshot:

I'm pretty much new to programming and following a course, please keep explanations very basic where possible..

Here's the code for the JS file. I've generated a basic Visual studio code Extension using Yo Code and NPM.

    // The module 'vscode' contains the VS Code extensibility API
// Import the module and reference it with the alias vscode in your code below
import { mands, window } from 'vscode';

// this method is called when your extension is activated
// your extension is activated the very first time the mand is executed

/**
 * @param {vscode.ExtensionContext} context
 */
function activate(context) {

// Use the console to output diagnostic information (console.log) and errors (console.error)
    // This line of code will only be executed once when your extension is 
    activated
    console.log('Congratulations, your extension "content-helper" is now 
    active!');

    // The mand has been defined in the package.json file
    // Now provide the implementation of the mand with  registerCommand
    // The mandId parameter must match the mand field in package.json
    let disposable = mands.registerCommand('extension.helloWorld', function () {
        // The code you place here will be executed every time your mand is executed

        // Display a message box to the user
        window.showInformationMessage('Hello World!');
    });

    context.subscriptions.push(disposable);
}
const _activate = activate;
export { _activate as activate };

// this method is called when your extension is deactivated
function deactivate() {}

export default {
    activate,
    deactivate
}

• Please show us the code causing this error. We will not be able to help you otherwise. – emeraldsanto Commented Apr 19, 2020 at 0:54
• Sure, I basically used "yo code" and NPM to create an Extension. – Shabbir Commented Apr 19, 2020 at 1:02
• Could you add more info for lanch.json – huoxudong125 Commented Jun 3, 2020 at 8:01

VS code extensions are run in a Node environment which does not natively support modules (So no import and export).

yo code only uses import when you create a TypeScript extension. For js extensions, yo code instead uses require:

const vscode = require('vscode');

To use import in a VS Code extension, you must pile the code down to target Node, either using TypeScript or a tool such as webpack
