Answer 1

My problem was that my node version was on 8.x.x but angular >= 8.x.x requires a node version >= 10.x.x

Im using nvm to change node version. Install it with like so (check link for windows usage)

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.2/install.sh | bash

after installation install node version 10.x.x

nvm install 10

then switch in terminal like this

nvm use 10
