React Capstone Jammming, surge: command not found

on the last step of the Jammming project, ran npm install – global surge, Spotify wouldn’t accept any redirect uri in the given format.
Did some digging here, saw that some folks have had success with localhost:3000/callback/, so I entered that in Spotify.js and in the settings of the app.
From the root directory of the project, I ran npm run build and cd into the build directory. When I attempt to to type surge into the command line, I get the message “command not found”.
Saw a suggestion here to try “npx surge”, same result.
Did some more digging online, remembered an issue I had at the introduction of node with Windows 10 and whitespace in usernames. Went back to this link:

tried what this dude did, still no dice. Any suggestions?
