Dependency conflict issue when running npm install in Builder Angular example project

[dhruvesh9]

Hi,

I cloned the Builder Angular example project (https://github.com/BuilderIO/builder/tree/main/examples/angular) to test it locally.

After running npm install, I encountered the following error:
npm error code ERESOLVE npm error ERESOLVE unable to resolve dependency tree npm error npm error While resolving: builder-angular-example@undefined npm error Found: [email protected] npm error node_modules/zone.js npm error zone.js@"^0.14.8" from the root project npm error npm error Could not resolve dependency: npm error peer zone.js@"0.14.7" from @builder.io/[email protected] npm error node_modules/@builder.io/angular npm error @builder.io/angular@"^3.1.1-0" from the root project npm error npm error Fix the upstream dependency conflict, or retry npm error this command with --force or --legacy-peer-deps npm error to accept an incorrect (and potentially broken) dependency resolution.

It seems like @builder.io/angular v3.1.1-0 requires [email protected], but the project installs [email protected], which causes a conflict.

Questions:

1. Is @builder.io/angular version 3.1.1-0 incompatible with [email protected]?
2. Should I try to install the dependencies using --force or --legacy-peer-deps, or is there a recommended fix for this issue?

To Reproduce:

1. Clone the Builder Angular example project
2. Run npm install

Expected behavior: Node modules should install successfully without dependency issues.

Additional context: My current environment details:

Node.js version: v22.9.0
npm version: 10.8.3

OS: Windows 10 x64

Thanks in advance for your help!

I'm not sure what else I need to do besides manually test this solution, but I have created a pull request that makes the zone.js peer dependency more lenient.
