Uncaught TypeError: Failed to resolve module specifier "mathjs". Relative references must start with either "/", "./", or "../".

Hi.

I downloaded mathjs using npm, but i'm having trouble actually using it. I need to use the complex numbers tools that the libray provides in one of my project's modules (a js file), but merely trying to import mathjs (as the documentation shows):

import { complex } from "mathjs";

Is enough to give this error:

Uncaught TypeError: Failed to resolve module specifier "mathjs". Relative references must start with either "/", "./", or "../".

Everything else in my project is working just fine.

Project folder structure:

How to reproduce the error and observe it:

1. Install mathjs using npm;
2. Try to import 'complex' from the mathjs library to the main.js module using the import { complex } from "mathjs command;
3. Open the html file inside the browser using Live Preview and then go the console.

I have also tried doing this:

import { complex } from "../node_modules/complex.js/complex.js"

, which returns this error in the browser's console:

Uncaught SyntaxError: The requested module '../node_modules/complex.js/complex.js' does not provide an export named 'complex'

Hi Jos.

I added the project's folder structure and how to reproduce the error in the main comment.

After cracking my head for hours, the solution i've found was to use a module bundler (Vite) and to use the import { create, all } from 'mathjs'; syntax to get it working. I didn't want to use Vite for such a small project, but that's how things have come to be.

Jos, before closing the issue, i'd like to know if there was a way to use the library without resorting to a module bundler, because it bloats my project massively. The documentation also doesn't mention the necessity of using one.

So I understand that you want to use the library as ES module and without any bundlers like discussed in #1928?

You can use the browser bundle if you don't want to use a bundler, like mathjs/lib/browser/math.js.

Yes, correct. That was my intention.

Thanks, i will use this solution next time i need to use the library.
