## Installation
|
|
|
|
Deno works on macOS, Linux, and Windows. Deno is a single binary executable. It
|
|
has no external dependencies.
|
|
|
|
### Download and install
|
|
|
|
[deno_install](https://github.com/denoland/deno_install) provides convenience
|
|
scripts to download and install the binary.
|
|
|
|
Using Shell (macOS and Linux):
|
|
|
|
```shell
|
|
curl -fsSL https://deno.land/x/install/install.sh | sh
|
|
```
|
|
|
|
Using PowerShell (Windows):
|
|
|
|
```shell
|
|
iwr https://deno.land/x/install/install.ps1 -useb | iex
|
|
```
|
|
|
|
Using [Scoop](https://scoop.sh/) (Windows):
|
|
|
|
```shell
|
|
scoop install deno
|
|
```
|
|
|
|
Using [Chocolatey](https://chocolatey.org/packages/deno) (Windows):
|
|
|
|
```shell
|
|
choco install deno
|
|
```
|
|
|
|
Using [Homebrew](https://formulae.brew.sh/formula/deno) (macOS):
|
|
|
|
```shell
|
|
brew install deno
|
|
```
|
|
|
|
Build and install from source using [Cargo](https://crates.io/crates/deno):
|
|
|
|
```shell
|
|
cargo install deno --locked
|
|
```
|
|
|
|
Deno binaries can also be installed manually, by downloading a zip file at
|
|
[github.com/denoland/deno/releases](https://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.
|
|
|
|
### 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](./command_line_interface.md).
|
|
|
|
### Updating
|
|
|
|
To update a previously installed version of Deno, you can run:
|
|
|
|
```shell
|
|
deno upgrade
|
|
```
|
|
|
|
This will fetch the latest release from
|
|
[github.com/denoland/deno/releases](https://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:
|
|
|
|
```shell
|
|
deno upgrade --version 1.0.1
|
|
```
|
|
|
|

Information about how to build from source can be found in the `Contributing`
|
|
chapter.
