looks like you didn’t run the npm install step of the module install
I’d suggest getting the new module MMM-GoogleAssistant that came out just this week.
it replaces both old modules and it much easier to install.
I’ve tried every variation. I’ve scrapped everything. Starting from scratch again. I guess I’ll come back if still an issue.
That is another issue. snowboy is related with MMM-Hotword, and that error says you didn’t or failed proper installation of that module. Read the instructions of installation.
