"`
nvm alias default
"`
Replace `
"`
nvm alias default 14.17.3
"`
7. You can verify the installation by typing the command "node -v" in the Terminal and pressing Enter. If the version is displayed, it means Node.js is successfully installed.
Pros:
– NVM allows you to easily manage multiple versions of Node.js on your Mac.
– You can switch between different Node.js versions depending on your project requirements.
– NVM provides a flexible and user-friendly way to install and manage Node.js versions.
