Start Node-RED
Once Node-RED has started, point a browser at http://192.168.178.33:1880
On Pi Node-RED works better with the Firefox or Chrome browser
Use node-red-stop to stop Node-RED
Use node-red-start to start Node-RED again
Use node-red-log to view the recent log output
Use sudo systemctl enable nodered.service to autostart Node-RED at every boot
Use sudo systemctl disable nodered.service to disable autostart on boot
To find more nodes and example flows - go to http://flows.nodered.org
Starting as a systemd service.

So what device have you installed NR on?
How did you do the install?
I installed nodered on a raspberry pi 4 with the normal install with
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)
nodered was going 4 hours ago there was a power loss in my house and as i restarted it was broke
Had you done anything else related to node.js on this device? The error says it cannot find the node command. That is an odd state to be in after the install script completes.
no i didnt do anything to the node.js i can reinstall nodered but i dont have any backup from the flow thats the real problem
i have the flow saved now so what can i do that i dont have to reinstall nodered
Try running the install script again. Depending on what has been corrupted that may fix it. You might be better to start again with a fresh card though. Make sure you have the full .node-red folder backed up, except for node_modules, which can be rebuilt.
Ok Thanks after reinstall everythig was back to normal
