-------------------
If the --global flag is not set, adds dependencies to the local project's configuration

is specified, installs all dependencies listed in package.json.

  deno install
  deno install @std/bytes

Global installation
-------------------

  deno install --global --allow-net --allow-read jsr:@std/http/file-server
  deno install -g https://examples.deno.land/color-logging.ts

To change the executable name, use -n/--name:

The executable name is inferred by default:
  - Attempt to take the file stem of the URL path. The above example would
    become 'file_server'.
  - If the file stem is something generic like 'main', 'mod', 'index' or 'cli',
    and the path has no parent, take the file name of the parent path. Otherwise
    settle with the generic name.
  - If the resulting name has an '@...' suffix, strip it.

To change the installation root, use --root:

  deno install -g --allow-net --allow-read --root /usr/local jsr:@std/http/file-server

To change the executable name, use -n/--name:
  deno install -g --allow-net --allow-read -n serve jsr:@std/http/file-server

The executable name is inferred by default:
  - Attempt to take the file stem of the URL path. The above example would
    become 'file_server'.
  - If the file stem is something generic like 'main', 'mod', 'index' or 'cli',
    and the path has no parent, take the file name of the parent path. Otherwise
    settle with the generic name.
  - If the resulting name has an '@...' suffix, strip it.

To change the installation root, use --root:
  deno install -g --allow-net --allow-read --root /usr/local jsr:@std/http/file-server

The installation root is determined, in order of precedence:
  - --root option
  - DENO_INSTALL_ROOT environment variable
