Wenn Sie MongoDB bereits installiert haben, versuchen Sie zuerst, mongod als sudo-Benutzer auszuführen. Ich hatte das Problem, weil mongod nicht als Superuser ausgeführt wurde.
Ich habe das O / P für beide Befehle ( Mongod und Sudo Mongod ) ganz unten eingefügt , das können Sie aber auch überprüfen
Versuchen Sie dies zuerst
sudo mongod
nicht das
mongod
Ich hatte MongoDB auf meinem MAC OS X Sierra 10.12.6 installiert, indem ich den folgenden Befehl nacheinander ausgeführt habe.
brew update
brew install mongodb --devel
brew services start mongodb
Anschließend wurde ein Verzeichnis erstellt, in das der Mongod-Prozess die Daten schreibt. Dies ist optional, da der Mongod-Prozess dies standardmäßig übernimmt. Weitere Informationen finden Sie in diesem nützlichen Handbuch unter https://docs.mongodb.com/manual/tutorial/install-mongodb-on-os -x /
sudo mkdir -p /data/db
Schließlich begann der Mongod- Prozess wie folgt
sudo mongod
Ausgabe von mongod (fehlgeschlagen) und sudo mongod (erfolgreich) auf meinem Terminal.

Dann habe ich ein neues Terminal geöffnet, um die MongoDB abzufragen . Es hat funktioniert.
