BACK-END DEVELOPMENT Quote API

I don’t know you: but i’m simple doing this project i" Quote API "n Full Stack Engineer Path.

Project requires to install their files and then start install the express server, but when i try to install and run, i always have this back in my terminal:

Blockquote
code: ‘MODULE_NOT_FOUND’,
requireStack: [ ‘/Users/lucalucci/Desktop/example_backend/server.js’ ]
}

Now, i have everything downloaded from the challenge project page, and it doesn’t work.
When i try to install alone an express.js server, it works. I think this is a bug, possible? Or someone could help me?

Thank you!
