Could you copy and paste the logs please.
Also, what version of node-RED are you using.
[ERROR TypeError: Cannot read property 'forEach' of undefined]
and after failed install, dont run again node red, and i must remove package heart-rate node that created in package module, to run again node red.
node red version: v1.2.5
Excuse me, I not typing English well.
I see that there is a problem with the node-red-contrib-ble-heart-rate node, already reported, but unfortunately not fixed - package.json error · Issue #1 · tomo-makes/node-red-contrib-ble-heart-rate · GitHub
You could try contacting the node author requesting that it is fixed.
so thankful for you.
try LoRa node, you are problem or not ...?
and how contact the node author ...?
Can you go to your user directory (on a Raspberry Pi it will be home/pi/.node-red) and then install the node by npm install node-red-contrib-lorawan
You will then see the full node install log, copy the whole of the log, and paste it, so we can see what is happening. There will be quite a few lines.

You have not run the node install command from within your user directory.
I don't use Windows, but isn't it \Users\<Username>\.node-red (perhaps a Windows user could confirm).
In your case that would be C:\Users\Mohammad\.node-red.
Also we don't recommend node 15 - for exactly these sorts of reasons. Many modules with native dependencies may not compile correctly. Please drop back to node14 or12.
Thanks bro.
Its worked. (version 12)
