Issue description

Following instructions as-is just doesn' t work.

Expected Behavior

Working.

Actual Behavior

Not working.

Steps to reproduce

I follow the exact instructions at https://www.npmjs.com/package/node-llama-cpp (npm install and copy/paste code into .js file)

I try running (only changing the line with the .gguf file to using a file on my harddrive) it I get:

Google recommends I change to:

//import {LlamaModel, LlamaContext, LlamaChatSession} from "node-llama-cpp";
const { LlamaModel, LlamaContext, LlamaChatSession } = require('node-llama-cpp');

So I do that (am I wrong or is it impossible for the example given in the README to work...?), and I get:

Node.js v20.5.1

So I put the awaits inside an async:

// Async hell.
(async () => {

    const q1 = "Hi there, how are you?";
    console.log("User: " + q1);
    
    const a1 = await session.prompt(q1);
    console.log("AI: " + a1);
    
    
    const q2 = "Summerize what you said";
    console.log("User: " + q2);
    
    const a2 = await session.prompt(q2);
    console.log("AI: " + a2);
    
})();

now I get:

At that point I just give up...

(Note this is after nearly an hour trying to get this module to work with ts-node, and utterly failing, despite trying DOZENS of things from Google and ChatGPT... I use thousands of modules from npm in ts projects, this is the first time I get this much trouble... whfich is why I failed back to trying to run it with node (instead of ts-node) to simplify the issue, and as you can see above, even that fails...)

I'm at a loss...

Any help welcome.

It's failing because you're using Imports outside of a node module. Nothing to do with this project. The node error message describes a fix - Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.

Therefore, rename your original file that uses Imports from .js to .mjs and run node filename.mjs and it will work

[giladgd]

@arthurwolf node-llama-cpp is an ES module, so you can only import it and cannot use it with require, and to do so your project has to be an ES module as well.

Just like the error you've got says:

(node:2540491) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.

You should add "type": "module" to the package.json of your project, and then the code will work for you.

I'll add a section in the getting started guide to explain this better.
