Import packge.json (using esm)

[vashian]

Do you want to request a feature or report a bug?

This is a bug report

What is the current behavior?

using oclif with esm and need to import package.json
running the command: oclif manifest and here's the output error:

mycli: Module 
    "file:///path/package.json" needs an import 
    assertion of type "json"
    Code: ERR_IMPORT_ASSERTION_TYPE_MISSING

but after following the instruction and import packge.json like this:

import pkg from '../package.json' assert { type: 'json' };

then I've got a warning:
ExperimentalWarning: Importing JSON modules is an experimental feature. This feature could change at any time

OS: Ubuntu 22.04.1 LTS x86_64
@oclif/core: 1.13.10

Hi @vashian, I don't think this issue is related to oclif but feel free to re-open this issue if I'm incorrect.

Both the error and the warning you're describing come directly from nodejs. Which version of nodejs are you using? Node didn't start supporting importing JSON files as modules until version 17.1.0.

See (these docs](https://nodejs.org/docs/latest-v19.x/api/esm.html#json-modules) for more info about the warning.
