Cast : failed to install

General
1

I am trying to install node-red-contrib-cast, but I get the message 'failed to install'.
Nodered is running on a Raspberry pi 2. So far I had no problems with other installs.
I did already run an update and upgrade.

Any idea how to fix ?

In a terminal change to the .node-red directory and run
npm install node-red-contrib-cast
and copy/paste the full result here. Preferably copy/paste rather than screenshot if possible.
Also tell us which version of node-red and nodejs you are using (node -v for the latter) and how you installed node-red.

here is the result

pi@theone ~ $ npm install node-red-contrib-cast

and here the version

I guess I installed node-red as root

kind regards

I don't think you did the first part of that.

When I asked how you installed node red I meant what you did in order to install it. The recommended way of installing for a Pi is
https://nodered.org/docs/getting-started/raspberrypi
If you didn't do that then it might be best to run the script there before doing anything else, then you can be confident you have a consistent set of tools.

Solved !

  1. the Original install was located in root. Ater a full re-intall of node-red it is now in located in home/pi
  2. I was not able to intall cast from palette. Eventually did it in the raspberry pi console. A clear error came out > not the right permissions… installed it as root. works fine now.

thanks

Once again you have failed to tell us the exact error, so we can only guess as to the exact cause, but a permissions error installing a node often means you have files in your home folder that are owned by root, which can happen if you install nodes locally using sudo. The solution is to change the ownership of all files in the .node-red folder to the correct user.
