Npm error when installing Zigbee2mqtt

When following the guide to install zigbee2mqtt on my pi with rasbian buster lite I get the following error when trying to get the version number of npm. What am I doing wrong? Everything up to this error looked okay.

-bash: npm: command not found

Is it installed?
Try this :

I thought it would be installed when using this:
sudo apt-get install -y nodejs git make g++ gcc as described.

I have tried on stretch lite and here it works fine.

I’ve not tried Buster yet. So I’m not sure.
I run on stretch as well. Works great.
If it’s not mission critical I would stick with stretch.

Unless someone else knows .

I will stick to stretch for now and try to pair some devices
thanks :slight_smile:
