The message is pretty clear, but even running the npm command on root, still getting the problem. One quick fix is executing the same command but with the sudo before the npm

sudo npm install -g learnyounode

It worked for me.

@davidlares I don't understand how you quick fixed it, you're recommending the same command as the OP

On my side I used

mkdir -p /tmp/tuto_node
cd /tmp/tuto_node
npm install learnyounode

then

./node_modules/learnyounode/bin/learnyounode

Note: I've been forced to ^C the npm install and relaunch it because it was stuck

These are not issues with learnyounode, but issues with installing global modules through npm. (this is not learnyounode specific). Thus I am closing this issue. There have been many explanations about this on https://github.com/nodeschool/discussions/issues?q=label%3Ainstallation+is%3Aclosed

Well, for information here is what I found relevant while digging through the given link
