[BUG] (node:63871) ExperimentalWarning: CommonJS module using require()

[songyang-dev]

Is there an existing issue for this?

• I have searched the existing issues
• Similar to [BUG] ExperimentalWarning: Support for loading ES Module in require() is an experimental feature and might change at any time #7857

This issue exists in the latest npm version

• I am using the latest npm

Current Behavior

Running npm creates a warning. My installation comes from Homebrew. When I reinstalled the newest version 10.9.1 with the URL in the README, it is still printing the warning.

-> % npm init
(node:64208) ExperimentalWarning: CommonJS module /opt/homebrew/Cellar/node/23.3.0/lib/node_modules/npm/node_modules/debug/src/node.js is loading ES Module /opt/homebrew/Cellar/node/23.3.0/lib/node_modules/npm/node_modules/supports-color/index.js using require().
Support for loading ES Module in require() is an experimental feature and might change at any time
(Use `node --trace-warnings ...` to show where the warning was created)
This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sensible defaults.

See `npm help init` for definitive documentation on these fields
and exactly what they do.

Use `npm install <pkg>` afterwards to install a package and
save it as a dependency in the package.json file.

Press ^C at any time to quit.
package name: (test) npm warn init canceled

Audit creates a different error code.

-> % npm audit
