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:

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

Using Homebrew:

brew install deno

Using MacPorts:

sudo port install deno

Using Nix:

nix-shell -p deno

Using asdf:

asdf plugin-add deno https://github.com/asdf-community/asdf-deno.git

# To install globally
asdf global deno latest

# To install locally (current project only)
asdf local deno latest

You can also build and install from source using Cargo:

cargo install deno --locked

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

Or using Winget (Windows):

winget upgrade deno

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
