But I am always getting version 8.10:

Solution

I am using nvm to switch between nodejs versions.
https://github.com/nvm-sh/nvm
Install nvm:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash
restart terminal
Install node 10.x:
nvm install 10
Switch to node 10.x:
nvm use 10
Check node version:
node -v
