Cannot install a new app to my DAO

Trying to add address-book to my DAO

dao install <dao address> address-book.aragonpm.eth --environment rinkeby

keeps returning the same error regarding truffle.js file not being present

It's true that the path to helpers/truffle.js doesnt exists:

> ls ~/.nvm/versions/node/v12.22.8/lib/node_modules/@aragon/cli/
aliases  config  dist  LICENSE  node_modules  package.json  schemas

Worth mentioning: node versioning issues, where yarn required v14, but I could only install aragon with node v12.

But also where is supposed to be this truffle.js file and what should be in it? I did follow the app building guide.

Thanks for opening your first issue in the Aragon apps repo! Someone will circle back soon ⚡

I copied truffle.js from ./dao-templates/templates/bare/truffle.js in the address-book app and it seems to help.
But still some issues about truffle

Error: Cannot find module '@aragon/os/truffle-config

Is this expected? Why isn't truffle.js not included in each app sub-folder in this project ?
