Three-gpu-pathtracer Installation Issue

Based on your error, it seems that three-mesh-bvh is a dependency of three-gpu-pathtracer that isn't being automatically installed. This is likely because it's a peer dependency rather than a direct dependency.

Solution

You need to install three-mesh-bvh separately:

BASHCopied
npm install three-mesh-bvh

This is a common pattern with ThreeJS addons and extensions - they often have peer dependencies that need to be installed manually.

Additional Context

When working with ThreeJS and its ecosystem of addons, it's important to:

1. Check the package's documentation for required peer dependencies
2. Make sure all dependencies are using compatible versions
3. Install all required packages explicitly

If you're using a bundler like Vite, you'll also need to make sure your import paths are correct. As mentioned in the ThreeJS documentation, import paths can differ between npm installations and CDN usage.

After installing three-mesh-bvh, your application should work correctly assuming there are no other missing dependencies.
