Sorry, but I am missing something with the install.

[Just-another-pleb]

I admit I had to do some restoration on the RasPi's NR install to get it working, as it was/is a long time since I have used it.

Anyway, I installed it and a very simple flow where I injected "Hello" to the node.

I get this error:

Error: Command failed: python2 "/home/pi/.node-red/node_modules/node-red-contrib-pifacecad/pfc_lcd.py" HelloTraceback (most recent call last): File "/home/pi/.node-red/node_modules/node-red-contrib-pifacecad/pfc_lcd.py", line 1, in import pifacecadImportError: No module named pifacecad

I know I have made a mistake, but am too stupid to really get what that is. Thanks in advance.

you not installed the dependencies. for install dependencies run the below command in your raspberry pi terminal.

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install python{,3}-pifacecad

thanks.

Thank you.

(But....)

This is what I get/see:

Reboot and same error.

Just noticed this too. I don't know if it is me, or what:

The error - first line:

Error: Command failed: python2

Yet I updated python3, yes?

[erfanjahanshahlo]

run below commands:

sudo aptitude install liblircclient-dev cython gcc python{,3}-setuptools python{,3}-dev
git clone https://github.com/tompreston/python-lirc.git
cd python-lirc/
make py2 && sudo python2 setup.py install

git clone https://github.com/piface/pifacecommon.git
cd pifacecommon/
sudo python2 setup.py install

git clone https://github.com/piface/pifacecad.git
cd pifacecad/
sudo python2 setup.py install

I am so sorry I was forgetting to put the 1,1: in front of the text.

All working now.

[Just-another-pleb]

Just a P.S. on this topic: Suggestion: If there is no valid prefix (1,1: for example) make it default to position 1,1
