NVM

Reference: https://github.com/nvm-sh/nvm

nvm stands for Node Version Manager.  it helps you manage and switch between different Node versions with ease. 

Create .zshrc file

Since macOS 10.15, the default shell is zsh and nvm will look for .zshrc to update, none is installed by default. Create and run the install script:

touch ~/.zshrc

If you use bash, the previous default shell, run touch ~/.bash_profile to create the necessary profile file if it does not exist.

Install NVM

You can install nvm using cURL or Wget. On your terminal, run the following:

Option 1. With cURL:

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

Option 2. Or with Wget:

wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.35.2/install.sh | bash

We can then run these 3 lines in the terminal in order to use NVM right away:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  
# This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

Check nvm install version

Install Multiple version of Node.js

LTS

you can install the most recent LTS release, using:

nvm install --lts

Latest

If you’re not sure what the latest version is, you can use the node alias:

nvm install node

specific version

You can install specific versions by running this command followed by the version you want. For example:

Option 1. Install 13.14.0

nvm install 13.14.1

Option 2. Install 13.14.X

nvm will then install Node.js version 13.14.X, where X is the highest available version. At the time of writing, thesis 1, so you’ll have the 13.14.0 version installed on your system

nvm install 13.14

Switching Between Versions

To switch through installed versions, nvm provides the nvm use command. This works similarly to the install command. So, you need to follow this by a version number or an alias.

Switch to the LTS release version:

nvm use --lts

Switch to the latest Node.js version:

nvm use node

Switch to Node.js version 13.14.0:

nvm use 13.14.0

Set to specific version as a default:

nvm alias default {version}

Listing Installed Instances

At any time you can check which versions you have installed by running:

nvm ls

You can also check what is the current version in use with the command:

nvm current
