Install Deno

A secure runtime for JavaScript and TypeScript.

See deno.land for more help.

• Linux manual install:

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

• Linux with Snap - from SnapCraft Mint instructions.

  $ sudo apt update
  $ sudo apt install snapd
  
  $ sudo snap install deno

• macOS:
  • Use curl command as for Linux.
  • Use Homebrew:

    $ brew install deno

macOS Homebrew notes

Installing on Homebrew gave me version 3 minor versions behind. The latest was 1.4. Using Deno's upgrade command got me to 1.7.

$ brew install deno
$ deno --version
deno 1.4 ...

$ brew upgrade deno
$ deno --version
deno 1.7.0 (release, x86_64-apple-darwin)
v8 8.9.255.3
typescript 4.1.3

That seems to have replaced the old one, as I still only have one Deno binary available when I check all with which -a deno.

Though it didn't seem to break Homebrew. But if Homebrew someday allows 1.5, will that downgrade my 1.7 to 1.5?

$ which -a deno
/usr/local/bin/deno
$ brew upgrade deno
Warning: deno 1.4.6 already installed`

Check installed version:

$ deno --version

Upgrade to the latest Deno:

$ deno upgrade
