Downloading NVM

NVM (Node Version Manager) has two main implementations:

1. nvm-windows: For Windows operating systems
2. nvm-sh: For Linux, macOS, and Windows Subsystem for Linux (WSL)

This guide will help you download the appropriate version for your operating system.

NVM for Windows

Latest Release

The latest stable release of NVM for Windows can be downloaded from the official GitHub repository:

Download NVM for Windows

Look for the latest release and download one of the following files:

• nvm-setup.zip: The installer package (recommended for most users)
• nvm-noinstall.zip: For manual installation without the installer
• nvm-setup.exe: Direct executable installer (if available)

System Requirements

• Windows 7 or later
• Administrator privileges for installation
• PowerShell or Command Prompt

Next Steps

After downloading NVM for Windows, proceed to the Windows installation guide for step-by-step instructions.

NVM for Linux and macOS (nvm-sh)

For Linux, macOS, and WSL, you don't need to download a separate file. The installation is done directly through a shell script.

Installation Script

You can install nvm-sh using either curl or wget:

Using curl:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.5/install.sh | bash

Using wget:

wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.5/install.sh | bash

Manual Download

If you prefer to download the script manually:

1. Visit the nvm-sh GitHub repository
2. Check the latest version number (currently v0.39.5)
3. Download the install script:

curl -o install_nvm.sh https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.5/install.sh

4. Make the script executable:

chmod +x install_nvm.sh

5. Run the script:

./install_nvm.sh

System Requirements

• Linux, macOS, or Windows Subsystem for Linux (WSL)
• Bash, Zsh, or other compatible shell
• curl or wget for downloading the installation script
• Git (required for the installation process)

Next Steps

After downloading the installation script, proceed to the Linux/macOS installation guide for detailed instructions.

Verifying Downloads

NVM for Windows

To verify the integrity of your NVM for Windows download:

1. Check the file size against the value shown on the GitHub releases page
2. Run a virus scan on the downloaded file
3. Verify the digital signature of the installer (if available)

NVM for Linux/macOS

The installation script automatically verifies the integrity of the downloaded files. If you want to manually verify:

1. Check the script content before running:

cat install_nvm.sh

2. Verify the GitHub repository URL is correct: https://github.com/nvm-sh/nvm.git

Troubleshooting Download Issues

Windows Download Issues

• If you're having trouble downloading from GitHub, try using a different browser or a download manager
• If your antivirus blocks the download, temporarily disable it or add an exception
• If you're behind a corporate firewall, try downloading from home or use a VPN

Linux/macOS Download Issues

• If you cannot access GitHub, check your network connection or firewall settings
• If you're in a region with restricted access to GitHub, consider using a VPN
• If curl or wget commands fail, ensure they are installed on your system:

# For Debian/Ubuntu
sudo apt install curl wget

# For macOS
brew install curl wget

# For CentOS/RHEL
sudo yum install curl wget

Alternative Download Methods

Using a Package Manager

On some systems, you can install NVM through a package manager:

macOS (using Homebrew)

brew install nvm

Linux (using package managers)

Note: It's generally recommended to use the official installation script instead of package managers for the most up-to-date version.

Using a Mirror

If you're having trouble accessing GitHub or need faster downloads, you can use a mirror:

For nvm-windows

Download from a mirror and then proceed with the normal installation process.

For nvm-sh

You can specify a mirror during installation:

export NVM_NODEJS_ORG_MIRROR=https://npmmirror.com/mirrors/node
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.5/install.sh | bash
