Node-RED - Node install - Error: `gyp` failed with exit code: 1

I need to install "red-contrib-socketcan" - https://flows.nodered.org/node/red-contrib-socketcan Problem is that I can't install it because node-gyp failes with exit code 1. Until now I couldn't find any solution. I am using a Banana Pi - M4 and it's running Debian 10 Buster lite

Here's the output:

10 Jan 12:05:02 - [warn] Installation of module red-contrib-socketcan failed:

Solution

In my case I completely missed the line that says:

ImportError: No module named ast

Normaly Python should have been installed. So I just checked it to be sure if python & python3 is installed. And it wasn't installed!

So I did the following:

Installing Python:

apt-get install python3-dev python3-pip
apt-get install python-dev python-pip

and checking/installing ast:

pip3 install ast 
pip install ast

Everything works fine now! Thank you for the Comment @hardillb. Otherwise I always would have missed this line.
