Installing Deno // Notes of bvfnbk

Deno is easily installed. Simply visit https://github.com/denoland/deno/releases and download the ZIP file matching your platform.

The ZIP file contains a single file executable deno (for macOS and Linux) which can be put into a directory of your choice, e.g.

deno-$VERSION/bin/deno

Please note: (macOS) Running the deno executable might be forbidden (as the developer cannot be verified). Run

xattr -d com.apple.quarantine deno-$VERSION/bin/deno

to remove the quarantine flag.

The following environment variables may be useful:

Environment Variable	Comment	Default
`DENO_DIR`	Cache (transpiled files, remote modules etc.)	`deno/` to be found in the default Operating System Cache directory
`DENO_INSTALL_ROOT`	Location to store scripts installed with `deno install`	`$HOME/.deno/bin`
`DENO_NO_UPDATE_CHECK`	Disable check for newer `deno` version (if set)	Not set

Please note:

Set DENO_DIR and DENO_INSTALL_ROOT for project-specific caches and scripts, e.g. using a .envrc file (managed by direnv).
IntelliJ
- Plugin: “Better Direnv”: The plugin does not (yet) support Deno run configurations.
