claude-mem does not appear to be installed.

Error message

claude-mem does not appear to be installed.

What it means

`npx claude-mem uninstall` begins with `isPluginInstalled()`; when it returns false the command warns that claude-mem does not appear installed and, in a TTY, asks whether to clean up leftover registration data anyway. Declining (or cancel) ends with 'Nothing to do.'.

Solutions

1. If leftovers may exist, answer yes to the cleanup prompt; non-TTY runs proceed with cleanup automatically.
2. If you expected an install, check the plugin location and re-run `npx claude-mem@latest install`.
3. Run uninstall again after a successful install if you want everything removed.

import { existsSync } from 'node:fs';
import { join } from 'node:path';
import os from 'node:os';

const pluginInstalled = existsSync(join(os.homedir(), '.claude', 'plugins', 'marketplaces', 'thedotmack'));

When it happens

Trigger: Run the uninstall command when the plugin files/marker are absent — install never completed, a previous uninstall already ran, or the plugin directory was removed manually.

Common situations: Double uninstall, half-failed install, plugin dir deleted by hand, or a different user/npm prefix owning the install.
