Could not parse Codex CLI version from "${output || '<empt

Error message

  Could not parse Codex CLI version from "${output || '<empty>'}". Continuing; plugin marketplace support requires ${MIN_CODEX_MARKETPLACE_VERSION} or newer.

What it means

Variant of the version gate: `codex --version` exits 0 but the combined stdout/stderr contains no \d+.\d+.\d+ semver, so `extractSemver` returns null. The installer warns with the raw output it saw and continues without a version verdict.

Solutions

1. Run `codex --version` and inspect the exact output it prints.
2. Update to a standard Codex CLI release whose --version emits a plain semver.
3. Re-run install afterwards.

import { spawnSync } from 'node:child_process';

const r = spawnSync('codex', ['--version'], { encoding: 'utf8' });
const output = `${r.stdout}\n${r.stderr}`.trim();
const hasSemver = /\d+\.\d+\.\d+/.test(output);
if (r.status === 0 && !hasSemver) {
  // unrecognized --version format: update codex before install
}

When it happens

Trigger: Codex prints a banner, localized text, or empty output for `--version`, so the semver regex finds no match.

Common situations: Dev/custom builds printing non-standard version strings, wrappers injecting extra output, or localization changing the format.
