Installation

Install the Deno runtime on your system using one of the commands below. Deno ships as a single executable with no dependencies, making installation quick and easy.

​
Quick Install

Use the installation script with curl:
curl -fsSL https://deno.land/install.sh | sh
Or install via Homebrew:
brew install deno

​
Installation Methods

Choose the installation method that works best for your platform and preferences.

​
Shell Script (Mac, Linux)

The shell script installer is the recommended method for macOS and Linux: 
curl -fsSL https://deno.land/install.sh | sh
This will download and install Deno to ~/.deno/bin/deno. You may need to add this to your PATH: 
export DENO_INSTALL="$HOME/.deno"
export PATH="$DENO_INSTALL/bin:$PATH"
Add these lines to your shell profile (~/.bashrc, ~/.zshrc, etc.) to make them permanent.

​
PowerShell (Windows)

For Windows users, the PowerShell installer is the recommended approach: 
irm https://deno.land/install.ps1 | iex
The installer will add Deno to your PATH automatically.

​
Homebrew (macOS)

If you have Homebrew installed: 
brew install deno
Homebrew will automatically manage updates via brew upgrade deno.

​
Package Managers (Windows)

Windows users have several package manager options: 
choco install deno

​
Verify Installation

After installation, verify that Deno is installed correctly: 
deno --version
You should see output similar to: 
deno 1.x.x (release, x86_64-apple-darwin)
v8 11.x.x
typescript 5.x.x

cargo build --release
The compiled binary will be at ./target/release/deno.

​
Updating Deno

Deno includes a built-in upgrade command: 
deno upgrade
This will download and install the latest version of Deno. To upgrade to a specific version: 
deno upgrade --version 1.40.0

deno upgrade --canary

​
Uninstalling Deno

To uninstall Deno, simply remove the executable and configuration directory: 
rm -rf ~/.deno
Then remove the PATH exports from your shell profile.
If you installed via a package manager, use the package manager’s uninstall command: 
# Homebrew
brew uninstall deno

# Chocolatey
choco uninstall deno

# WinGet
winget uninstall DenoLand.Deno

# Scoop
scoop uninstall deno

​
Environment Setup

For the best development experience, consider setting these environment variables: 
# Set the Deno installation directory (if using shell installer)
export DENO_INSTALL="$HOME/.deno"
export PATH="$DENO_INSTALL/bin:$PATH"

# Configure Deno cache location (optional)
export DENO_DIR="$HOME/.cache/deno"

​
Editor Setup

For the best development experience, install the Deno extension for your editor:
