Firebase error on npm run deploy

[Nardol]

I followed all the instruction provided in the README file but when running npm run deploy, I have the following error:
"Error: No currently active project.
To run this command, you need to specify a project. You have two options:

• Run this command with --project <alias_or_project_id>.
• Set an active project by running firebase use --add, then rerun this command.
  To list all the Firebase projects to which you have access, run firebase projects:list.
  To learn about active projects for the CLI, visit https://firebase.google.com/docs/cli#project_aliases

Having trouble? Try firebase [command] --help"
Firstly, I cannot find the firebase binary.
I also tried to modify the deploy command to include my project id but also error.
I didn't find any answer to this question.
What can I do to deploy successfully?
What did I miss in the readme file?

In fact I modified the command to add the firebase login before the deploy --project= so I logged in, but after I have the error: Error: Failed to get Firebase project testsmarthome. Please make sure the project exists and your account has permission to access it.
What is wrong here? My project is well-spelled.

In fact it looks like this project is not deployable, there is alway a new error.
After again modifying something I have an error specifying billing is not enabled, i swtiched engine version from 10 to 8 as specified here: https://stackoverflow.com/questions/63932639/400-billing-account-for-project-is-not-found-billing-must-be-enabled-for-activa
And now, I have a 403 when deploying:
"> rollup -c rollup.config.js

src/my-app.js → public...

After re-trying, I had the error specifying engine version 8 cannot be used now.
Solving an error creates two new errors...

How could it be possible to deploy this project in fact?
I though the readme file provided all instructions to run this project but it does not seems to be the case.
Or a node version requirement issue?
If someone has successfully deployed and was able to test the project recently, I could be really interested please.

@Nardol Thanks for the report, as shown in https://firebase.google.com/support/faq#expandable-9 Firebase Functions now require billing to be turned on for Node.js >= 10, filed #533 for us to update the documentation.
