I was trying to use homebridge-ui to update home bridge and one of its plugins today when this error message popped up:

execvp(3) failed.: No such file or directory.

To get around it, I logged in to the headless Mac mini, opened Terminal, and pasted in:

npm install -g homebridge@1.6.0

It installed without a hitch. Returning to homebridge-ui in a web browser I was able to initiate the plugin update and this time it worked. I’m not sure why, but I’ll take it as a win and move on.
