Issue running Hello World; cannot find module

Thanks for the reply Dist. If I do that, I receive an error starting “Cannot find module hapi.” If I do an npm install hapi (which succeeds) and rerun the command, I get “Cannot find module 'c:…root\manifest.json”

I see the command is looking in the root folder for the manifest and not my project folder. If I change the directory for the command to be:

node services/backend -l manifest.json

I receive the error: Cannot find module ‘c:…\root\my-extension\manifest.json.’ As far as I know, a manifest was not indicated to be created in this directory during this tutorial.
