[Bug]: Claimed Node.js >= 16.10.0 support missing in Rsbuild >= 1.4.2

[aweebit]

Version

npmPackages:
    @rsbuild/core: 1.4.5 => 1.4.5

Details

Running Rsbuild >= 1.4.2 with Node.js 16.10.0 results in the following error:

node_modules/@rsbuild/core/dist/index.js:20
import promises, { constants as promises_constants } from "node:fs/promises";
                   ^^^^^^^^^
SyntaxError: The requested module 'node:fs/promises' does not provide an export named 'constants'
    at ModuleJob._instantiate (node:internal/modules/esm/module_job:124:21)
    at async ModuleJob.run (node:internal/modules/esm/module_job:179:5)
    at async Loader.import (node:internal/modules/esm/loader:178:24)
    at async main (node_modules/@rsbuild/core/bin/rsbuild.js:16:22)

The reason is that the node:fs/promises module only exports constants starting from Node.js versions 16.17.0 and 18.4.0 (reference).

The current workaround is to use a patch for node_modules/@rsbuild/core/dist/index.js that includes this:

-import promises, { constants as promises_constants } from "node:fs/promises";
+import promises from "node:fs/promises";
+import { constants as promises_constants } from 'node:fs';

(unnecessary, see commands below)

Reproduce Steps

npm init -y
npm i -D @rsbuild/core
nvm install 16.10.0
npx rsbuild

I will fix this. It's worth mentioning that we plan to drop support fot Node 16 in Rsbuild 1.5, so it's recommended to upgrade to a newer version of Node.js.

[chenjiahan]

Unfortunately, the import { constants } from 'node:fs/promises' is introduced in a third-party dependency (open) so it's not easy for us to fix it.

I will set the correct engine requirement to fix this, see #5567
