Trynode -v to see whether you've installed node. I think your node not works.

nvm is the environment managment for node. If you are using nvm, you should brew install nvm, and use nvm install version-of-node-you-want-to-install to install node, and use nvm use the-version to let node works.

Whole install chain is:

• brew install nvm, to install nvm, which is environment/version management for node.

• nvm install 10.3.0, to install node and npm

• npm install -g yarn, to install yarn

• use node -v, npm -v, nvm -v, yarn -v to check if they all works.
