Cannot access node-red


#1

Hi. It's been 2 days i have started with node-red, i think i have installed a wrong package.
Before it was working fine then i see that when i tried to run node-red:

Start Node-RED

Once Node-RED has started, point a browser at http://192.168.0.169:1880
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.

Well a couple of things

  1. you have managed to a couple of packages that overlap with existing package names. For now you will have to uninstall them manually. (We are trying to handle this situation better in the next release).

You need to find where they are installed (usually your ~/.node-red/ directory but may vary depending on how you installed.) - and then run npm uninstall node-red-contrib-pushover node-red-contrib-ovia-os

  1. whatever node you have for handling sms is failing to access a directory. Which node is that ? Either there are some more pre-requisites required to et it up correctly or there is a bug in that node.

#3

First can you post the start of the log, from the Welcome message. To see this you can run

node-red-stop
node-red-start

Then sort the Type already registered messages. These probably mean that you have installed two nodes that provide the same node types. Have you installed two pushover nodes? In the case of ovia I suspect possibly you have installed node-red-contrib-os as well as the ovia one. Fix those by uninstalling one of the duplicates and see where that takes you.


#4

Colin the error that is causing the crash is

The duplicate nodes don't help - but...


#5

I suspected there was another problem, but my strategy is always to fix the problems that have obvious solutions first, sometimes you find unexpectedly that it also fixes other problems.


#6

Hi.
Thanks for the reply, i accidently remove the node-red directory because i thought of fixing the problem that way..

how can i remove all the dependencies and start node-red from the start?

Thanks.
Marc.


#7

Which node red directory did you remove?


#8

The node-red directory entirely.
thanks.
marc.


#9

Which node-red directory? Do you mean the .node-red directory in your home folder? If so then all you have to do is to restart node-red and it will recreate the directory with an empty flow.


#10

the node-red directory yes.
i typed node-red-start
and i didnt see any node-red directory :frowning:

thanks.
marc.

thanks for helping me.

#12

As Dave pointed out previously, this missing directory appears to be causing the crash.
Does it exist? If so, what are its permissions? If not, try creating it and restarting node-red.

And you still need to get rid of these duplicate nodes. Have you tried to uninstall them, or do you need help with that also?


#13

type that:
npm uninstall node-red-contrib-pushover node-red-contrib-ovia-os

got that:

Looks like you did not run that from your .node-red directory.

here are my directories:

i cant find it, i accidently erase it :frowning:

#16

It is a hidden directory, since it starts with a dot. Try ls -la from your home directory. Or use
cd ~/.node-red and see if it puts you into that hidden dir. If so, then you should be able to run
npm uninstall node-red-contrib-pushover node-red-contrib-ovia-os

Thank You shrickus , problem solved :slight_smile:

Thanks.

good night :slight_smile:
