Codex marketplace ${MARKETPLACE_NAME} is already registere

Error message

  Codex marketplace ${MARKETPLACE_NAME} is already registered from another source; replacing it with ${marketplaceRoot}.

What it means

`registerCodexMarketplace` runs `codex plugin marketplace add <root>`. When that fails because MARKETPLACE_NAME is already registered pointing at a different source, the installer warns, runs `codex plugin marketplace remove MARKETPLACE_NAME`, then re-adds from the new root. The warning means the old registration was detected and replaced.

Solutions

1. No action required — the installer removes and re-adds the marketplace automatically.
2. Verify afterwards: `codex plugin marketplace list` should show the new root.
3. If the warning appears on every install, remove the marketplace manually (`codex plugin marketplace remove claude-mem`) and reinstall.

import { spawnSync } from 'node:child_process';

const list = spawnSync('codex', ['plugin', 'marketplace', 'list'], { encoding: 'utf8' });
const staleRegistration = list.stdout.includes('claude-mem') && !list.stdout.includes(expectedMarketplaceRoot);
if (staleRegistration) {
  spawnSync('codex', ['plugin', 'marketplace', 'remove', 'claude-mem']);
}

When it happens

Trigger: Codex already has the claude-mem marketplace registered from a different path (old install location, moved checkout, different npm cache dir) while a new install registers a new marketplaceRoot.

Common situations: Reinstalling after moving the repo, switching between local dev and npm installs, or npm cache paths changing between Node versions.
