It’s been a while since I did a fresh install so I don’t remember if the node version matters. I’m surprised you’re still getting a 5.0.0 error if you deleted the version from your package.json. Try running:
npm install serialport
from the command line. Then, from the folder where your package.json is saved, run:
npm install
Then try to start the server.

Me too! And it was quite difficult then. I had ZERO knowledge of Raspberry Pi at that time. Now I cannot remember how I did it. Here we go…
pi@raspberrypi:~/Downloads/smartthings-nodeproxy $ npm install serialport
npm WARN deprecated mkdirp@0.5.4: Legacy versions of mkdirp are no longer supported. Please update to mkdirp 1.x. (Note that the API surface has changed to use Promises in 1.x.)

Thank you for using serialport!

Since the warning calls out mkdirp being an old version, you probably also need to run:
npm update
to get node.js to update all of its installed packages. Then try the lines I posted again to install serialport.
Ok. And you’re sure that USB0 is the right port?
Affirmative.
Still getting that same error.
Try:
npm install mkdirp
and/or:
npm update mkdirp
I had hopes…but alas…

Maybe it’s time to do a complete wipe of raspbian and install completely fresh?
For the fifth time in 24 hours? LOL
oh! ouch.
ok. What if I send you an image of my Raspbian and you install that image on your Rpi? Then just change the plugins to Russound?
Sounds good to me 
ok. I’m running a Pi Zero W so i’m not entirely sure if that will work on yours.
I don’t think that it will. Thanks anyway.
OK, I think that I have a running version. Does anyone have an autoboot rc.local file they would be willing to share?
Here are my step by step instructions for setting up autoboot. It’s for a different plugin, but everything should be the same.
Was working well 2 hours ago. Unplugged the RPi. Ate dinner. Plugged it back in. Now it won’t do anything but turn the speaker on/off. Nothing else. It was throwing this error before and was working. Not working now. Any thoughts?
