Got error when following tutorial of Animal-Kingdom

I received the following messages when I run ‘npm run start’ from my MacBookPro with MacOS Sierra 10.12.6. Has anyone ever encountered it before?

Js-MacPro:animal-kingdom wangjohnson$ npm run start

It has been fixed after updating the version of node in my system.
Would the required version be mentioned in the Tutorial?

1 Like yes, it should. I’ll mention that in the tutorial. Thank you for the suggestion.
