Missing value for ${argument}.

Error message

Missing value for ${argument}.

What it means

parseMutationArguments looked at the token after a value-taking Nasiko argument (e.g. --version or --install-dir) and found it missing or flag-shaped. The argument named in the message requires a following value token.

Source

Thrown at scripts/nasiko.js:36

Usage:
  ecc nasiko status [--install-dir <absolute-path>] [--json]
  ecc nasiko install --version v0.1.0 --yes [--install-dir <absolute-path>] [--json]
  ecc nasiko install --version v0.1.0 --dry-run [--install-dir <absolute-path>] [--json]
  ecc nasiko uninstall --version v0.1.0 --yes [--install-dir <absolute-path>] [--json]

The installer is opt-in, accepts only ECC-qualified pinned releases, downloads
content-addressed OCI artifacts from registry.nasiko.dev, verifies SHA-256
digests before extraction, and never executes fetched shell or PowerShell code.

Solutions

1. Pass a value immediately after the flag (e.g. `<flag> <value>`); the value was missing or consumed as another flag.

When it happens

Trigger: Triggered when nasiko.js rejects the current invocation: Missing value for <value>.

Common situations: Occurs while running scripts/nasiko.js with invalid arguments, missing flags, or a failing external dependency; the guard at scripts/nasiko.js:36 aborts the command with this message.
