Install NVM, NodeJS, Yarn via Homebrew

install-nvm-nodejs-yarn-homebrew.md

Prerequisites

• Homebrew should be installed (Command line tools for Xcode are included).

Getting start

Part A: Install NVM and NodeJS

1. Install nvm via Homebrew

   $ brew install nvm

2. Add following line to your profile. (.profile or .zshrc or .zprofile)

   # NVM
   export NVM_DIR=~/.nvm
   source $(brew --prefix nvm)/nvm.sh

3. Close and open your terminal again. Or Choose one from the following command once for reload your profile. (.profile or .zshrc or .zprofile)

   Example

   • $ source ~/.profile
   • $ source ~/.zshrc
   • $ source ~/.zprofile

4. Verify nvm is installed

   $ nvm --version

5. Check all available version by this command

   $ nvm ls-remote

6. Install NodeJS (Recommended to install LTS version. Current LTS is Fermium)

   $ nvm install --lts=Fermium

7. Check installed NodeJS in your machine.

   $ nvm ls

8. Set global nodejs version to environment.

   $ nvm use default

See more about nvm : https://github.com/creationix/nvm

Part B: Install Yarn and Linked nvm node to Homebrew

1. Install yarn via Homebrew

   $ brew install yarn

2. Remove node dependencies from Homebrew

   $ brew uninstall node --ignore-dependencies

3. Checkout node in environment $PATH

   $ which node

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

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

   $ brew doctor

5. Create blank folder and create symbol link node folder from nvm for yarn in Homebrew.

   $ nvm current => v14.15.0 (Latest LTS: Fermium) (This should be Global node version)

   $ mkdir /usr/local/Cellar/node

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

6. Overwrite node, npm and npx from linked node in /usr/local/Cellar/node to /usr/local/bin/ homebrew

   $ brew link --overwrite node

7. Checkout ls -la /usr/local/bin to see overwrited node, npm and npx

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

   $ brew doctor

9. Prevent Homebrew upgrading node version

   $ brew pin node

10. Enjoy ! ❤️

Part C: Upgrading, To change node.js version and Re-configure Homebrew

1. Checkout nvm for to use node version (For this example case I will use LTS Fermium)

   $ nvm list

   $ nvm list
   ->      v12.13.1
           system
   default -> 12.13.1 (-> v12.13.1)
   node -> stable (-> v12.13.1) (default)
   stable -> 12.13 (-> v12.13.1) (default)
   iojs -> N/A (default)
   unstable -> N/A (default)
   lts/* -> lts/erbium (-> v12.13.1)
   lts/argon -> v4.9.1 (-> N/A)
   lts/boron -> v6.17.1 (-> N/A)
   lts/carbon -> v8.16.2 (-> N/A)
   lts/dubnium -> v10.17.0 (-> N/A)
   lts/erbium -> v12.13.1

   * See more about nvm : https://github.com/creationix/nvm

2. Remove the symbol link which we linked node in Homebrew /usr/local/Cellar/node

   $ rm -rf /usr/local/Cellar/node

3. Unpin node in Homebrew for upgrading yarn

   $ brew unpin node

4. Upgrade yarn

   $ brew upgrade yarn

5. Continue on Part B 2. - 10. steps again.
