About NVM
NVM is a version manager for Node.js, designed to be installed per-user and invoked per-shell. It works on any POSIX-compliant shell (sh, dash, ksh, zsh, bash) and supports platforms like Unix, macOS, and Windows WSL.
Installation and Updates
Install & Update Script
To install or update NVM, run the following script using either curl or wget:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.2/install.sh | bash
wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.2/install.sh | bash
This script clones the NVM repository to ~/.nvm and updates your shell profile to load NVM automatically. If the script updates the wrong profile file, set the $PROFILE environment variable to the correct file path and rerun the script.
