This is an NPM bug, either update to the latest patch version of NPM or use an alternate package manager.

We also started facing this error in last days in our team. We didn't change the Angular CLI version, nor the npm version.
So I'm wondering what changed that this error started to happen in ng new commands
(Side note: we're building an Angular 3rd party library installable with our custom schematics - that's why we run ng new in our tests often 😉 )

I've also noticed that a workaround to avoid edgesOut error is to use --test-runner=karma (instead of the default vitest)!

So I only guess the problem is caused by some recently-rearranged tree of transitive dependencies behind Angular and/or Vitest that cause conflicting peerDpes constraints, that npm 10 cannot handle and it crushes?

I confirm, switching to Node24+npm11 fixes the problem (i.e. no need for --test-runner=karma workaround)

Here https://angular.dev/reference/versions Angular is listed as compatible with Node ^22.22.3 which according to this: https://nodejs.org/en/about/previous-releases ships with npm version v10.9.8.

Should not Angular v22 bump minimum required node version? Otherwise it is misleading IMHO.

[alan-agius4]

The Node.js compatibility information defines support for the Node.js runtime itself, not the bundled npm version.

Node.js is fully compatible, and this failure is caused by a bug in npm. Package managers including NPM can be updated independently of Node.js, and developers can also use other package managers such as yarn or pnpm. Bumping the minimum required Node.js version would unnecessarily restrict developers whose setups work without issues.
