Node won't install, please help

General

I have tried to install widgetlord node so I can use a Pi-Spi 4-20ma current loop sensor to get data from a sensor, I followed instruction but getting this error..

Widgetlord instruction are at: Getting Started with PI-SPI Libraries – Widgetlords Electronics

Very new to node-red/raspberry pi, please help!

pi@raspberrypi:~ $ npm install node-red-contrib-widgetlords

if you want to use the command line you need to be in your .node-red directory.

Much easier is to use the manage palette option under the menu in node-RED

3

Hi ukmoose

do you mean to:

"node-red-start"

Then type the same code?

"npm install node-red-contrib-widgetlords"

Sorry, just new and am stuck on this one step! I have played with and have had everything else running once I can get this node installed.

thanks

4

no

After you have started node red, go to the menu in node red and from the manage palette option you can install new nodes

5

Okay, this is the log it comes up with through the web dashboard in manage palette

Remove it via commandline npm remove node-red-contrib-widgetlords
Then retry from gui.

If you ever get stuck in npm hell. Generally the quickest and cleanest way - though it shouldn't be the first thing you do generally, better to understand what went wrong if you can - is do simply delete the node_modules folder:

cd ~/.node-red
rm package-lock.json
rm -R node_modules
npm install

That will cleanly reinstall all of the packages marked in your package.json file. So make sure that is correct first. Every time you install a package (as long as you have reasonably up-to-date versions of Node.js and npm) whether from the NR admin ui or command line, it gets added to package.json.

I now always remove the lock file as well if I'm having issues as that can be the cause of some issues. The lock file isn't generally needed in NR installations.

Note, as always, I've assumed you have a "standard" install of Node-RED which puts your userDir as ~/.node-red (and the equivalent on Windows). If you use an installation scheme like mine, it will be in a different place as noted by the command used to start NR.

OK, something in your list of nodes is either itself way out of date or uses another package that is out of date and deprecated.

You will want to find out which. The npm debug log may give you a clue as to which node is causing the issue.

By the way, I've just posted my previous advice to my blog since this seems to be cropping up a lot at the moment.

It should appear here in a short while:

18

I would also note that this node only has 2 commits 1 year ago. That wouldn't seem to bode well for its maturity or stability.

19

I really appreciate your help. I have had this working, it was until last week when I tripped over a power cable which shorted supply to the pi and corrupted it, lost it all and building up again. But I am stuck on getting only the widgetlords node going. I have a water pressure sensor sitting on a 4-20ma current loop board attached to the pi, I believe this node is the only way to get that data value in, if there is another, then I will be okay.

Sorry for the questions or naivety, I am fairly novice and new so unsure about a fair but. Such as finding the npm log or what might be causing my issue.

Thanks

Sorry, not familiar with that and this is the first time I've noticed that node. I can't really make sense of their library but it seems to be written just for their hardware? There have only been 3 releases for their libraries which means that either the code quality is amazingly high or they really aren't investing in software development. That's just an opinion of course since I've not looked in detail nor tried their products. At a casual glance, the software would certainly put me off.

Either way, first thing now is to find out which node is causing the install issues. Then to try to get the node developers to fix things.
