i dont nknow what the hell i am doing. i was using bitcore before. i think i have messed up my node.

I was frustrated as well I think you can only use v4 and not npm@latest
nvm install v4
I can’t remember the command but it told the os just to use v4

do i have to remove npm and replace it with v4?

no idea
here is the commands I used
sudo apt install curl
curl -o- | bash
nvm install v4
nvm use v4
sudo apt-get install libzmq3-dev build-essential
npm install -g bitcore-node
npm install -g bitcore-node@latest
bitcore-node create mynode
cd mynode
bitcore-node install insight-api
bitcore-node install insight-ui
bitcore-node start
