Manual download Jump to heading#

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.

Testing your installation Jump to heading#

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.

If you see "command not found" Jump to heading#

If deno --version reports command not found, the install directory isn't on your PATH yet. To fix this:

• Open a new terminal window or restart your shell so the updated PATH is picked up. This is the most common cause — the install script updates your shell rc file, but existing shell sessions don't see the change until they reload.
• Confirm the install directory is on your PATH. The shell install script defaults to ~/.deno/bin on macOS and Linux; for npm-based installs, run npm config get prefix to find the directory containing the global bin.
• If you customised the install location, the shell install script's install root can be overridden with the DENO_INSTALL environment variable, in which case the binary lives at $DENO_INSTALL/bin/deno.

Updating Jump to heading#

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

deno upgrade

Or using Winget (Windows):

winget upgrade DenoLand.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
