Node-red-start on raspberry pi not working

hary · 15 May 2018 16:40

Hi to everybody.

I had to upgrade nodejs and npm to latest version to be able to use MCP4725 digital to analog converter library on my Raspbian RPi on Stretch.

And now, node red has disapeared from the menu.
But most important, at command line "node-red-start" is not found.

I can only start with the command "node-red" which could be fine but also the command "node-red-stop" isn't found !

And I don't know how to stop node-red ?

Any help too make things working as before with "node-red-start" and "node-red-stop" ?

How did you upgrade ? did you use our upgrade script ?
Which versions of node and npm are you now on ?

If you just use node-red to start then ctrl-c will stop it

node-red-start and-stop should be in the /usr/bin directory if they are still there… but obviously may now be pointed to the wrong place… there are also instructions in our docs to tell you how to e-install them manually -
https://nodered.org/docs/hardware/raspberrypi#adding-autostart-capability-using-systemd

I cant really tell how I upgraded as I tried so many things because I couldn’t get things working at first.
But I don’t think, I’ve used your script.
Version are :
v9.11.1 for nodejs.
5.6.0 for npm.
I’ll have a deeper look at your doc.

Thanks for your reply indeed.

I have the same problem and could not finde a solution. Maybe there is a lak of understanding in linux things?

Situation:
the command ./node-red works to start, but node-red-start fails with the folowing error. To be able to start the Node-RED independend while booting the Raspi, I need to get it working with node-red-start.

Versions
[info] Node-RED version: v0.18.7
[info] Node.js version: v8.11.3
[info] Linux 4.9.41-v7+ arm LE

Hardware: RPi3

what I did
I installed Node-RED somehow some days ago and started playing arround. Becaus I didn't had a entry in a menue like in a tutorial, I desided to upgrade to the newest version of node-RED, what I hadn't. The Upgrade I did with the folowing line.

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

thanks a lot for your ideas and help!

ukmoose · 13 August 2018 17:14

so when you run that script line did everything finish with a tick?
(You can run it again and see...)

If you use the command node-red-log what does it return?

tsknightstorm · 13 August 2018 17:37

Script
This I forgot to mention. The folowing line finishes with a "+". In this part, I am not shure if this is correct. So I just tryed to input "nvm use lts/*" bevore starting with node-red-start.

Using NVM to manage Node.js + please run nvm use lts/* before running ./node-red

Full Script Output

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

All done.
  You can now start Node-RED with the command  ./node-red
  Then point your browser to localhost:1880 or http://{your_pi_ip-address}:1880

Use the node-red-log command to see why the service is stopping.

tsknightstorm · 13 August 2018 19:53

In my last post I added the ouput of the node-red-log, but was not able to finde the problem with it, becaus I don't know what 'exit-code' or "status=127/n/a" should mean.

knolleary · 13 August 2018 19:57

My apologies, I was expected a bit more output from node-red itself... but this shows it isn't even starting the node process at all. Some there must be something fundamentally off here.

When you run node-red manually (by running the command node-red) - can you share the full log output?

I wonder if there's a permissions issue here with the node-red user directory it is trying to use.

dceejay · 13 August 2018 21:23

I suspect it's nvm getting in the way... you may need to do the update to nodejs 8 from within nvm itself as that whole environment is a bit weird.

tsknightstorm · 14 August 2018 05:55

You mean the output direct in the console while starting the process with "node-red"? Here we go.

Sorry if I understand some things wront. I'm about learing all things with linux.

oh maybe I found the problem... I was up to finde out how to update nvm. So I ended up with some thing like "nvm update npm" and got the folowing. By the way, would this be the correct way or do I just update npm with this and not nvm?

After that I checked the disk space, what shows me the reason. It is full... I just had a 8GB SD Card for my RPi arround.

dceejay · 14 August 2018 08:07

Or (seeing as you are starting over) - try the Raspbian minimal install version image which does fit well under 8GB, and then install Node-RED directly (without nvm - as per our docs. https://nodered.org/docs/hardware/raspberrypi

tsknightstorm · 14 August 2018 10:19

thanks a lot for that hint! I was able to fix all my problems with start again with raspian minimal.

what I did to solve the problems

Install Raspbian minimal on a 8GB SD Card for my RPi3
install MQTT Server Mosquitto by command line
install NodeRed from this description https://nodered.org/docs/hardware/raspberrypi
set nodered to startup with sudo systemctl enable nodered.service

oooo . look at you... on 0.19 already !!!

StrongTown · 23 December 2018 15:07

For what it's worth, I have rpi3B running stretch (Debian) with update and upgrade done. When I did the update to node.js 10.14.2 I encountered exactly the same problem. Every time I run node-red-start it tells me

Node-RED is not yet fully installed

and runs the loop.

Suggested fixes here so far have not helped me. I can run NR by using 1 of 2 commands in the CLI, either ./node-red or node-red. Behaviour is fine using either one however I have to leave the terminal window open and cannot now find any way to get NR to start automatically upon boot or restart.

(Oddity: Not sure why NR states "Node.js version: v6.15.1" when it starts, nvm tells me I am using 10.14.2, but an email node wont run cause it too complains I have to have node.js above v8.)

If you haven't tried

sudo rm -rf /usr/lib/node_modules
sudo rm -rf /usr/bin/node

give it a go and then re-run the install script again

Colin · 23 December 2018 15:23

If node red says it using v6.x in the startup log (which I presume is what you mean) then that is the version it is using. I haven't used nvm so don't know much about it.

On the installation problem, delete the file /var/log/nodered-install.log then run the bash <(curl script and post the install log file here.

knolleary · 23 December 2018 15:41

Please don't suggest this without the corresponding caveat that this will be remove all npm modules that have been installed - including any installed unrelated to node-red.

When running as a service, it will not pickup any of your nvm environment configuration and will fall back to your system installed node version.

StrongTown · 23 December 2018 15:46

I wonder now why it says 'nodered' not installed?
