You will need Node.js and npm to be installed on your system. Node.js installer is not recommended, since the Node installation process installs npm in a directory with local permissions and can cause permissions errors when you run npm packages globally. Node version manager like nvm is usually recommended as explained below.

  • nvm: Node version manager to install Node.js and npm:
    • Windows:
      1. Donwload the latest release of nvm-windows.
      2. Click on .exe file to install the latest release.
      3. Complete the installation wizard
      4. When done, you can confirm that nvm has been installed by running:
      nvm -m
    • Unix/MacOS:
      1. In your terminal, run the nvm installer by using cURL or Wget commands depending on the command available on your device. These commands will clone the nvm repository to a ~/.nvm directory on your device:
      curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash

#or

wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
      1. Update your profile configuration: Running either of the above commands downloads a script and runs it. The script clones the nvm repository to ~/.nvm, and attempts to add the source lines from the snippet below to the correct profile file (~/.bash_profile, ~/.zshrc, ~/.profile, or ~/.bashrc). If it doesn't automatically add nvm configuration, you can add it yourself to your profile file:
      export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")" 
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
      1. When done, you can confirm that nvm has been installed by running:
      command -v nvm
      1. If you run into problems, you can check the complete documentation.
  • Node.js and npm: Use nvm to install, and use, the version of Node.js and npm defined in the .nvmrc file: 
    nvm use
    nvm install
    Verify it worked by running: 
    node --version
    npm --version
