Trying to run nodejs script with npm run build

Question

I was trying to run this script: https://github.com/drenther/bdnd_example, but then I got this error: npm ERR! Invalid name: "Line up the heroes"

I've tried reinstalling everything multiple times.

Error log:

the npm package name must not contain space or capital letters change the name in your package.json file to something like lineuptheheroes (just for test) and try again, also check the documentation here for how to write a valid name.
