In the "current" liveBook version, section 2.1.3, there is a missing space before the "--save-dev" option:
 npm install electron–-save-dev

should be:
npm install electron –-save-dev

Makes a difference when you use the liveBook "copy" button.

Double-checked the manuscript and it looks like it's fine in the Word document. I'll follow-up with the publisher.
