Part B: Install Yarn

1. Install yarn via Homebrew and remove node dependencies from Homebrew

   $ brew install yarn

   $ brew uninstall node --ignore-dependencies

2. Checkout node in environment $PATH

   It should be return => /User/<your's-user-name>/.nvm/versions/node/<latest-node-lts-version>/bin/node

3. Checkout brew doctor there should show message WARNING missing yarn dependencies

   $ brew doctor

4. Create symbol link from nvm for Homebrew. Pick a choice which suitable for you.

   a. This is for those who installed only one version via nvm

   $ ln -s ~/.nvm/versions/node/ /usr/local/Cellar/

   b. If you installed multiple node versions via nvm. You should create symbol link by current global version. Following this commands

   $ nvm current => v10.16.0 (Latest LTS: Dubnium) (This should be Global node version)

   $ mkdir /usr/local/Cellar/node

   $ ln -s ~/.nvm/versions/node/<latest-node-lts-version>/ /usr/local/Cellar/node

5. Checkout brew doctor again. There shouldn't have WARNING message.

   $ brew doctor
