VT Command Installation Guide

The vt command is VibeTunnel’s convenient wrapper that allows you to run any command with terminal sharing enabled. This guide explains how the installation works and how to manage it.

​
Installation Behavior

When you install VibeTunnel via npm, the vt command installation follows these rules:

​
Global Installation (npm install -g vibetunnel)

  • Checks for existing vt command to avoid conflicts with other tools
  • If no vt command exists, creates it globally
  • If vt already exists, skips installation and shows a warning
  • You can still use npx vt or vibetunnel fwd as alternatives

​
Local Installation (npm install vibetunnel)

  • Configures vt for local use only
  • Access via npx vt within your project

​
Platform Support

​
macOS and Linux

  • Creates a symlink to the vt script
  • Falls back to copying if symlink creation fails
  • Script is made executable automatically

​
Windows

  • Creates a .cmd wrapper for proper command execution
  • Copies the actual script alongside the wrapper
  • Works with Command Prompt, PowerShell, and Git Bash

​
Common Scenarios

​
Existing VT Command

If you already have a vt command from another tool: 
# You'll see this warning during installation:
⚠️  A "vt" command already exists in your system
   VibeTunnel's vt wrapper was not installed to avoid conflicts
   You can still use "npx vt" or the full path to run VibeTunnel's vt
Alternatives:
  • Use npx vt (works globally if installed with -g)
  • Use vibetunnel fwd directly
  • Manually install to a different name (see below)

​
Manual Installation

If automatic installation fails or you want to customize: 
# Find where npm installs global packages
npm config get prefix

# On macOS/Linux, create symlink manually
ln -s $(npm root -g)/vibetunnel/bin/vt /usr/local/bin/vt

# Or copy and rename to avoid conflicts
cp $(npm root -g)/vibetunnel/bin/vt /usr/local/bin/vibetunnel-vt
chmod +x /usr/local/bin/vibetunnel-vt

​
Force Reinstallation

To force VibeTunnel to overwrite an existing vt command: 
# Remove existing vt first
rm -f $(which vt)

# Then reinstall VibeTunnel
npm install -g vibetunnel

​
Troubleshooting

​
Permission Denied

If you get permission errors during global installation: 
# Option 1: Use a Node version manager (recommended)
# With nvm: https://github.com/nvm-sh/nvm
# With fnm: https://github.com/Schniz/fnm

# Option 2: Change npm's default directory
# See: https://docs.npmjs.com/resolving-eacces-permissions-errors

​
Command Not Found

If vt is installed but not found: 
# Check if npm bin directory is in PATH
echo $PATH
npm config get prefix

# Add to your shell profile (.bashrc, .zshrc, etc.)
export PATH="$(npm config get prefix)/bin:$PATH"

​
Windows Specific Issues

  • Ensure Node.js is in your system PATH
  • Restart your terminal after installation
  • Try using vt.cmd explicitly if vt doesn’t work

​
Uninstallation

The vt command is removed automatically when you uninstall VibeTunnel: 
npm uninstall -g vibetunnel
If it persists, remove manually: 
rm -f $(which vt)
# On Windows: del "%APPDATA%\npm\vt.cmd"
