Warning: Error closing watcher:

Error message

Warning: Error closing watcher:

What it means

FileWatcher.stop() warns when closing an individual fs.FSWatcher throws. Watchers are iterated and each close() is wrapped in try/catch so one failing close doesn't abort shutdown of the rest.

Solutions

1. Ignore — the watcher is being torn down anyway; the warning is cosmetic
2. Avoid double-stop: guard stop() with a running flag
3. Ensure watched directories still exist before stop, or detach deletions first
4. Upgrade the CLI if double-close was fixed in a newer version

Example fix

// before
stop() {
  this.watchers.forEach(w => w.close());
}
// after — idempotent stop
stop() {
  this.watchers.forEach(w => { try { w.close(); } catch {} });
  this.watchers.clear();
  this.running = false;
}

// Make close idempotent so double-stop never throws
if (!this.running) return;

this.watchers.forEach(w => { try { w.close(); } catch (e) { /* swallow: teardown */ } });
this.watchers.clear();

When it happens

Trigger: watcher.close() throwing on an already-closed or invalidated watcher (EBADF), or on some platforms when the watched directory was removed before close.

Common situations: Watched project directories deleted or renamed before stop(); rapid start/stop cycles (resume calls stop) closing watchers twice; platform quirks on Windows/network mounts.
