Unable to install a worldmap node

Dashboard
1

Hello, I've created my Node-RED dashboard via Raspberry Pi. My Node-RED and my PI did not let me install the worldmap.

Like the other poster, I got the exact same error when I tried to install node-red-contrib-web-worldmap.

On my Pi directory, I have entered cd /home/pi/.node-red/ npm install node-red-contrib-web-worldmap. I only got a bunch of error dialogues as per screenshot below.

Any assistance much appreciated.

Does the PI have internet connectivity?
Is it behind a proxy?

Quick test - try ping 8.8.8.8 and curl www.google.com - do you get a good response?

Is the pi connected to your network and the internet? Try
ping -c 3 8.8.8.8
which will ping google 3 times
[EDIT] Ahh @Steve-Mcl beet me by micro seconds!

Hi @Steve-Mcl, @zenofmud
Thank you for the fast response!

Seems to me like my Pi is connected to my home network (not a proxy).

Any other idea why I cannot install the worldmap node?

Your device is not reaching the internet (3 errors) you need to fix that then you can install.

Ahh ok, I didn't realise the 3 errors means my device doesn't reach the Internet.

I did everything in this website, but my Node-RED still doesn't install the worldmap. Could you kindly advise on any other way I can let my device connect to my Internet?

Is the pi connected to your router by wifi or by ethernet or not connected to the router at all?

It's connected to my router by wifi.

What do you see if you run
ifconfig

[Edit] Also what do you get for
traceroute 8.8.8.8

[Further edit] Also probably worth posting /etc/wpa_supplicant/wpa_supplicant.conf and /etc/dhcpcd.conf Blank out any sensitive information obviously.

So here's what I got so far:

ifconfig

ipconfig

traceroute 8.8.8.8

traceroute
traceroute819Ă—109 7.74 KB

12

For the /etc/wpa_supplicant/wpa_supplicant.conf and /etc/dhcpcd.conf
I only got Permission denied.
denied

13

You need to use

sudo cat /etc/wpa_supplicant/wpa_supplicant.conf
sudo cat /etc/dhcpcd.conf

1- Also what OS are you running on the Pi
2 - did you install NR using the bash script?

14

What came after that in the traceroute? It may take a little time to complete.
What to you see if you run the same traceroute 8.8.8.8 in the PC? If you are using windows you might need to google to find how to do the equivalent on the PC.

tracert 8.8.8.8

For sudo cat /etc/wpa_supplicant/wpa_supplicant.conf, I got:

For sudo cat /etc/dhcpcd.conf I got a very lengthy response:

@zenofmud
I'm on Windows 10 and yes, I used a bash script to install NR.
First I typed in

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

then sudo systemctl enable nodered.service , reboot sudo reboot

That all looks ok, I think we need the full response from the traceroute on pi and PC. something is blocking your internet access.

19

missing a default gateway and perhaps also missing a dns host setting

I did the traceroute on pi and PC (I assume you meant cmd?)

For the Pi, it looks the same old and the full response.
