Node-red bash curl script install fails on Coral Dev board

wb666greene · 25 August 2019 19:18

Google used some "weird" and apparently poorly documented "Mendel-Chef" Debian variation. I managed to get OpenCV 4.0.0 to build on it following some instructions I'd found via Google search (although trying 4.1.0 failed horribly with these instructions). My AI code runs nicely on this, about the same a the Pi4B. The main advantage is its a nice small package with the TPU build in as opposed to being an external Dongle and it has a built in fan. The Pi4 needs a fan to run the AI workload. Now I need to install node red to complete the system.

Unfortunately the bash curl install script fails:

All packages are up to date.

Sudo apt-get install npm fails.Nodejs in installed and is 4.8.2. Curious that a "Google" product would be so out of date with nodejs.

Am I out of luck, or is there some reasonably easy fix?

Try installing node manually. You would need to apt uninstall the v4 version first. Then follow the instruction on the nodejs web site. Hopefully that would get node 10 installed. Then retry the script

wb666greene · 27 August 2019 20:18

I finally got around to trying it, and got nodejs and npm installed from the nodejs web site arm64.xz file and re-ran the bash curl script. But when I got to:

All done.
  You can now start Node-RED with the command  node-red-start

when I did node-red-start:

mendel@Coral:~$ node-red-start

Node-RED is not yet fully installed

Fetching Node-RED update.
...

So I let the update run.

When I got to:

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

Would you like to start Node-RED now (y/N) ? y

It appears I'm stuck in an installation/update loop.

Node-RED is not yet fully installed

Fetching Node-RED update.

 
This script will remove versions of Node.js prior to version 7.x, and Node-RED and
if necessary replace them with Node.js 10.x LTS (dubnium) and the latest Node-RED from Npm.

Any ideas on how to fix?

dceejay · 28 August 2019 18:42

hmm - so what do the commands node -v and npm -v report ? and which node ?
(we may have to go fully manual on this - but no matter)
Once we get nodejs back to a decent state (ie node 10.x and npm 6.x) - we should be able to do
sudo npm i -g --unsafe-perm node-red
This won't install the service files etc - but they may already (now) be in place having run the script several times :-)...
Then try node-red-start - if that fails - just try node-red - which won;t stat it as a service but hopefully will at least then run. (we can work from there)

wb666greene · 28 August 2019 19:23

mendel@Coral:~$ node -v
v10.16.3
mendel@Coral:~$ npm -v
6.11.2
mendel@Coral:~$ which node
/usr/bin/node

This is the symlink I made following the nodejs.org installation instructions. I removed the 4.8 nodejs that got installed as part of the initial failure before re-runing the bash curl script after installing node.

Nothing of note (to me) in the log file from the last "loop":

mendel@Coral:~$ cat /var/log/nodered-install.log

I'm stuck and stumped. The Coral Development board would make a nice AI host, cost is good for the performance considering it has the TPU "built-in", but its a weird system and documenting how to set it up so a "normal" person could just buy one and follow along and expect it to work at the end is beyond me at this point.

I can do what I do with node-red in other ways, but the strength of the node-red that I use is its "portability" I've used it on Jetson Nano, Odroid XU-4, AtomicPi, I3 "MiniPC" along with my desktop development system. The dashboard let me make a simple UI that "normal" people can use to control the system from a cell phone web browser.

not really... - it's the failure for the install to add the links into the correct place that is the problem.
can you try the raw command node /home/mendel/AI/LorexAI/node-v10.16.3-linux-arm64/lib/node_modules/node-red/red.js

How do I fix it so the "normal" node-red-start and systemctl enable commands work?

What symlinks do I need to make, or scripts do I need to edit to make up for what the installer script failed to do?

create symlinks to both of those lines above - one to /usr/bin/node-red the second to /usr/bin/node-red-pi

Thanks for all you help.

It appears to be working correctly now. I'll know for sure after I reboot it, but the sudo systemctl enable nodered.service seems to have completed without errors. I installed the dashboard and a couple of other extra nodes I use.
