Question

im trying to install a nodejs application but I keep getting the same error about "node-gyp" failing to rebuild.

Answer 1

It seems you have a conflict with an older package that is getting in the way.
Try below commands helped me to resolve the issue, might help you too... these commands might need sudo access
npm cache clean -f
npm install -g n
n stable
npm install npm -g
So above solves the problem when there is any conflict in packages version.... but by looking at logs it says make: g++: Command not found Which means you need to install developer tools

Answer 2

have you tried installing node-gyp via apt-get install:
apt-get install node-gyp

Answer 3

The command g++ is not found, so you need to install the g++ package (along with build-essential which includes other packages that are required to build/compile programs):
sudo apt-get install build-essential g++
