node fs imports problems

[einar-hjortdal]

Flow version: 0.193.0

Expected behavior

no errors

Actual behavior

Importing fs/promises causes an error

import {
  readFile,
  writeFile,
  cp,
  mkdir
} from "fs/promises";
/**
 * results in the following error
 * Cannot resolve module `fs/promises`.Flow(cannot-resolve-module)
 */

importing fs.copySync causes an error

import { cpSync  } from "fs";
/**
 * results in the following error
 * Cannot import `cpSync` because there is no `cpSync` export in `fs`. Did you mean `rmSync`?Flow(missing-export)
 */

Hi,
as a temporary (or not so temporary) solution you could install flow-typed node environment. which support fs/promises.
https://flow-typed.github.io/flow-typed/#/env-definitions

For cpSync, better to add it here in core definitions I guess.
