In case you didn’t find a solution yet, a user by the name sdetweil just helped me with a similar problem with my RPi 3 B+ running the latest Rasbian Stretch.

Here is the link to that discussion for everyone else who is stuck at this step too:

I’m trying to set up MMM-Assistant on my mirror and keep coming across the same issue. I am so close, but whenever I enter…

node google-auth.js

…I get the error below. What am I missing? It looks like it can’t locate “google -client-secret.json” but I don’t see a step anywhere where that should have been created.

node google-auth.js internal/modules/cjs/loader.js:550 throw err; ^ Error: Cannot find module '/home/pi/MagicMirror/modules/MMM-Assistant/assets/google-client-secret.json' at Function.Module._resolveFilename (internal/modules/cjs/loader.js:548:15) at Function.Module._load (internal/modules/cjs/loader.js:475:25) at Module.require (internal/modules/cjs/loader.js:598:17) at require (internal/modules/cjs/helpers.js:11:18) at new Auth (/home/pi/MagicMirror/modules/MMM-Assistant/node_modules/google-assistant/components/auth.js:26:15) at new GoogleAssistant (/home/pi/MagicMirror/modules/MMM-Assistant/node_modules/google-assistant/index.js:21:16) at Object.

Thanks for all your help.

@bhepler This worked, thank you!
