Thanks for filing a report. I'd love to take a look at this but I'm not sure how I can reproduce this error on my end. Do you have a repository you can share where we can run the given command deno run -A npm:yo webapp to reproduce the error?

I believe

$ deno run -A npm:yo webapp

is a very neat equivalent, compared to node

$ npm install --global yo generator-webapp
$ yo webapp

And yeoman generate project scaffold.

So, should run command within any empty directory.

Thank you for providing the steps to reproduce this issue. I can see the error on my machine now.

Can confirm that the issue is that deno doesn't shim the module.parent property. For reference: Node's documentation has a little passage on how it's supposed to work: https://nodejs.org/api/modules.html#moduleparent .

I just tried on Deno v2.1.2 and this works correctly: deno run -A --unstable-unsafe-proto npm:yo webapp.
