Problem installing node-red-dashboard

Dashboard
1

Hi,

I had a very nice working node-red,tick stack, mosquitto installation on my Rpi4. I was getting better and better in building flows..proud to show them to friends :wink: After a stupid installation of my webcam my whole setup, every file was gone to the owner www data ??.

Anyway I could mount my sdcard from my Synology NAS and save essential files from node-red and after a fresh OS and node-red installation I'm back again with all my flows....but missing my dashboard nodes. I can't install them from the palette nor from the commandline?
Below is my logfile can anyone help me to solve this problem?

Kind regards,

That suggests that possibly you had nodes installed that are not in your package.json
The Port in Use error is because you have not stopped an already running instance of node red before starting a new one.
If you go to your .node-red directory and run
ls -al
what does it show?
Also try the install using the command line and see what happens this time, also from the .node-red directory
npm install node-red-dashboard

Thanks Colin,

Problem solved.
I think Port in Use was the problem cause after installing the node-red-dashboard nodes, one must restart node-RED and if there was an instance of node-RED running I will not see the new dashboard nodes.

I did a commandline install and reboot, and my nodes are back again :wink:

You can do node-red-stop then node-red-start instead of reboot.

Thanks Steve I knew....I thought: sudo reboot now are less characters to type :wink:
