How to disable import of .mjs modules?

Question

JavaScript

Hey!
I have a script that imports a library . The infer library in turn imports another library: And here is the problem with it: When building, I get an error:
import infer from 'tern/lib/infer'
require("acorn-loose")

ERROR in ./node_modules/acorn-loose/dist/acorn-loose.mjs 28:13-17
    Can't import the named export 'Node' from non EcmaScript module (only default export is available)

Its package.json has 2 parameters:

{
  ...
  "main": "dist/acorn-loose.js",
  "module": "dist/acorn-loose.mjs",
  ...
}

If I delete the dist/acorn-loose.mjs file, then the build succeeds.
Tell me how to disable the import of dist/acorn-loose.mjs from the "module" section without interfering with the code of the library itself?
Thank you!
