Angular CLI >= 20.1.0 - Error [ERR_REQUIRE_ESM]

[SebastianPost1996]

Which @angular/* package(s) are the source of the bug?

cli

Is this a regression?

Yes

Description

As of CLI version 20.1.0, running any ng command, regardless of the project and even in a global context, results in the error below.
Version 20.0.6 does not result in an error.

Unknown error: Error [ERR_REQUIRE_ESM]: require() of ES Module C:\Users\SebastianPost\AppData\Roaming\npm\node_modules\@angular\cli\node_modules\yargs\helpers\helpers.mjs from C:\Users\SebastianPost\AppData\Roaming\npm\node_modules\@angular\cli\src\command-builder\command-module.js not supported.
Instead change the require of C:\Users\SebastianPost\AppData\Roaming\npm\node_modules\@angular\cli\node_modules\yargs\helpers\helpers.mjs to a dynamic import() which is available in all CommonJS modules.

Please provide the environment you discovered this bug in (run ng version)

Angular CLI: 20.1.0
Node: 22.18.0
Package Manager: npm 10.9.3
OS: win32 x64

Unfortunately, we are unable to replicate the issue as described. This type of error may indicate a local system configuration issue. Potentially involving multiple versions of Node.js installed on the system. Node.js v22.18.0 supports synchronous ESM require usage (https://nodejs.org/api/modules.html#loading-ecmascript-modules-using-require).

Thank you @clydin, it was a local issue in my node setup and after a clean reinstallation it's working again. I'm not sure what exactly the issue was, but I'll list all the steps that I took for reference.

1. Run a system search for "node.exe". I discovered that an older version of my Webstorm had a v22.12.0 installation of nodejs which I deleted.
2. Remove Angular CLI from npm and PATH.
3. Perform a complete removel of nodejs as described in this thread: https://stackoverflow.com/a/20711410/25373102
4. Remove the NODE_OPTIONS environment variable. (I had no-experimental-require-module enabled which might be related to the issue)
5. Restart System.
6. Fresh install of node and Angular CLI
