Plugin "${pluginId}" is not installed

Error message

Plugin "${pluginId}" is not installed

What it means

After validating the id format, uninstallPlugin checks both user and project installed-plugin registries via #findInBothRegistries. If the plugin id has no entries in either scope, there is nothing to remove and it throws this error.

Solutions

1. Verify the exact installed id via the plugin list for both scopes, then retry
2. Run from the correct project directory if the plugin was installed in project scope
3. If already uninstalled, no action needed — treat this as success in idempotent scripts
4. Check that the @marketplace part matches where the plugin was installed from

Example fix

// before
await manager.uninstallPlugin("formatter@old-marketplace");
// after
await manager.uninstallPlugin("formatter@community"); // id confirmed via installed-plugins list

const installed = await manager.listInstalledPlugins(); // both scopes
const target = `${name}@${marketplace}`;
if (!installed.some(p => p.id === target)) {
  console.log(`${target} is not installed; nothing to do`);
  return;
}
await manager.uninstallPlugin(target);

try {
  await manager.uninstallPlugin(pluginId);
} catch (err) {
  if (err instanceof Error && err.message.includes("is not installed")) {
    // idempotent uninstall: already gone, treat as success
  } else throw err;
}

When it happens

Trigger: uninstallPlugin("name@marketplace") where neither the user-scope nor project-scope registry contains that id — plugin never installed, already uninstalled, wrong marketplace suffix, or wrong working directory (project registry is project-scoped).

Common situations: Uninstalling from a different project directory than the one where the plugin was project-installed; double-uninstall after the first succeeded; marketplace suffix mismatch (installed from "acme" but uninstalling "name@other").
