Installation

Deno works on macOS, Linux, and Windows. Deno is a single binary executable. It has no external dependencies.

On macOS, both M1 (arm64) and Intel (x64) executables are provided. On Linux and Windows, only x64 is supported.

Download and install

deno_install provides convenience scripts to download and install the binary.

Using Shell (macOS and Linux):

curl -fsSL https://deno.land/x/install/install.sh | sh

Using PowerShell (Windows):

iwr https://deno.land/x/install/install.ps1 -useb | iex

Using Scoop (Windows):

scoop install deno

Using Chocolatey (Windows):

choco install deno

Using Homebrew (macOS):

brew install deno

Using Nix (macOS and Linux):

Build and install from source using Cargo:

Deno binaries can also be installed manually, by downloading a zip file at github.com/denoland/deno/releases. These packages contain just a single executable file. You will have to set the executable bit on macOS and Linux.

Docker

Testing your installation

To test your installation, run deno --version. If this prints the Deno version to the console the installation was successful.

Use deno help to see help text documenting Deno’s flags and usage. Get a detailed guide on the CLI here.

Updating

To update a previously installed version of Deno, you can run:

deno upgrade

This will fetch the latest release from github.com/denoland/deno/releases, unzip it, and replace your current executable with it.

You can also use this utility to install a specific version of Deno:

deno upgrade --version 1.0.1
