Install and Update nvm

Install or upgrade nvm from the official source using script, git, or manual methods.

Workflow

1. Identify platform and shell (macOS, Linux, WSL, Alpine; bash/zsh/fish).

2. Install via curl or wget:

   # Using curl
   curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash
   
   # Using wget
   wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash
   

3. Verify the profile was updated (the script writes to ~/.bashrc, ~/.zshrc, or ~/.profile):

   # Required lines in your profile:
   export NVM_DIR="$HOME/.nvm"
   [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
   [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"
   

4. Verify installation:

   # Restart terminal, then:
   nvm --version
   

5. Override PROFILE if the auto-detection picked the wrong file:

   PROFILE=/path/to/custom/profile curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash
   

Notes:

• The install script writes to the detected profile unless PROFILE is explicitly set.
• For restricted networks, use the nvm-mirror-and-auth skill instead.
• Usage, .nvmrc, or troubleshooting belong to other nvm-* skills.
