Upgraded to node v8.9.0 from v6.10.2, homebridge wont' start

Was running homebridge successfully using node v6.10.2. I upgraded to 8.9.0 by doing the following. nvm install 8 nvm reinstall-packages 6.10.2 nvm use 8 npm uninstall -g homebridge npm install -g homebridge

Then i manually started homebrigde sudo -u homebridge /home/pi/.nvm/versions/node/v8.9.0/bin/homebridge -U /var/homebridge/

received that error that i paste below.

I tried npm rebuild and receive the same error when trying to start. i’ve tried npm uninstall of all my homebridge plugins and re-installed them all. Same error. I can’t seem to figure this out! Any ideas would be appreciated.

I had the same issue. Try this, it’s solved my problems

sudo npm install --unsafe-perm mdns 
cd /usr/local/lib/node_modules/homebridge
sudo npm rebuild --unsafe-perm

I had this too with nvm, where I had node 10 as default although I am using node 8 for homebridge. My systemd script to start homebridge using a bash login shell would load node 10 and try to run the homebridge from node 8, and it would have the version mismatch error. Setting node 8 as my default fixed it, although I think updating the systemd script to switch node version should also work.
