Cannot use import statement outside a module

[JonathanWilbur]

Hello, when importing this in a Javascript (clarifying that it is not Typescript) program, I get the following error:

(node:64227) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
(Use `node --trace-warnings ...` to show where the warning was created)
[REDACTED]/node_modules/nsfwjs/dist/esm/index.js:46
import * as tf from "@tensorflow/tfjs";
^^^^^^

Even if I go in nsfwjs's package.json and add "type": "module" manually, I get another strange error:

node:internal/modules/esm/resolve:265
    throw new ERR_MODULE_NOT_FOUND(
          ^

}

My application is a single file that has an extension .mjs and I have "type": "module" in my package.json.

My suspicion is that this has been tested with (1) TypeScript that compiles to CommonJS, and (2) Javascript / CommonJS, and the ESM module never worked properly. I am not sure what it would take, though; the package.json looks correct to me.

For reference, I am also importing several other ESM modules in my main.mjs prior to this one, so this isn't a problem with loading ESM modules in general.

I am using Node.js v20.16.0.

Thanks in advance for your help. I'd be happy to offer more information or even contribute code to fix this.

Bump. I have the same issue on nsfwjs@4.1.0 with node v20.16.0 and SvelteKit & vite.

I am having this issue with SvelteKit but using TypeScript not JavaScript. Did anyone figure out how to get this imported

[JonathanWilbur]

I did this in a TypeScript project and it worked for me: import * as nsfwjs from "./node_modules/nsfwjs/dist/cjs/index.js";.

That's obviously sloppy; you shouldn't have to do it. But it works.

Thanks for the temp fix @JonathanWilbur. I got it to work with that but importing the /esm/index.js. Haven't tested my full code yet, this looks more hopeful than manually importing TensorFlow and recreating the library
