This looks like a permission issue. npm is notorious for spawning new shells, and when it does the permissions of the sudo are lost. Try this instead.

su   <- enter your root password
npm install -g https://github.com/sfeakes/homebridge-sprinklerd.git

How to change root passwords?

[sfeakes]

That depends on a ton of things. On a new install you can usually run ‘sudo password root’
