Issues installing node-red core

General
1

I've tried various ways to install node-red on my Raspberry PI 4 running Debian

It doesn't seem to install the core when I run the command line script

bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)

Running Node-RED install for user empiric-device at /home/empiric-device on debian

This can take 20-30 minutes on the slower Pi versions - please wait.

  • Stop Node-RED \u2714*
  • Remove old version of Node-RED \u2714*
  • Node option not specified : --node18 or --node20*
  • Leave existing Node.js : v20.4.0 Npm 9.7.2*
  • Clean npm cache -*
  • Install Node-RED core \u2718 *
  • Move global nodes to local -*
  • Leave existing nodes -*
  • Install extra Pi nodes \u2714*
  • Add shortcut commands \u2714*
  • Update systemd script \u2714*
  •                                  *

Any errors will be logged to /var/log/nodered-install.log
All done.
You can now start Node-RED with the command node-red-start

  • or using the icon under Menu / Programming / Node-RED*
    Then point your browser to localhost:1880 or http://{your_pi_ip-address}:1880

  • WARNING ###*

  • DO NOT EXPOSE NODE-RED TO THE OPEN INTERNET WITHOUT SECURING IT FIRST*
  • Even if your Node-RED doesn't have anything valuable, (automated) attacks will*
  • happen and could provide a foothold in your local network*
  • Follow the guide at Securing Node-RED : Node-RED*
  • to setup security.*

  • ADDITIONAL RECOMMENDATIONS ###*

    • Remove the /etc/sudoers.d/010_pi-nopasswd file to require entering your password*
  • when performing any sudo/root commands:*
  •  sudo rm -f /etc/sudoers.d/010_pi-nopasswd*
    • You can customise the initial settings by running:*
  •  node-red admin init*
    • After running Node-RED for the first time, change the ownership of the settings*
  • file to 'root' to prevent unauthorised changes:*
  •  sudo chown root:root ~/.node-red/settings.js*

Hello @dnguyen01123 , welcome to the forum.

  1. Just to clarify, your login on the Raspberry Pi is empiric-device?

  2. What do these commands show you?
    ls -al ~
    sudo df -h

  1. Have you looked for clues in this file?

  2. Try this to force a reinstallation of node.js:

bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered) --node18

If it works, you can repeat it but specifying --node20

  1. when I force install using the codes it seems like it works , and then I did the v20 and this is what I got

nodered.service: Scheduled restart job, restart counter is at 2.

Stopped Node-RED graphical event wiring tool.

Started Node-RED graphical event wiring tool.

Your ls -al ~ output shows that /home/empiric-device is indeed the home directory but no .node-red directory has been created there. On the other hand, there is a node_modules directory, which I would expect to see inside .node-red.

I don't know what circumstances might lead to this result, I wondered if the root filesystem was full but df -h shows that it's not.

Did you run the install script using sudo? This might suggest that you did (but you should not have).

Now install Node-RED
sudo: npm: command not found

This is odd - seem like that although it reports the version of nodejs and npm (and thus can find the commands) it then seems to say it can't find them and fails to complete... I'm going to suggest retrying the script (again) but this time add the parameter --node20 to force the re-install of nodejs. Do this as your usual user (not root or sudo).
