Si vous avez déjà installé MongoDB, essayez d'abord d'exécuter mongod en tant qu'utilisateur sudo, j'étais confronté au problème car je n'utilisais pas mongod en tant que superutilisateur.
J'ai collé l'o / p pour les deux commandes ( mongod et sudo mongod ) tout en bas, vous pouvez vérifier cela aussi mais
Essayez d'abord ceci
sudo mongod
pas ça
mongod
J'avais installé MongoDB sur mon MAC OS X Sierra 10.12.6 en exécutant la commande suivante dans l'ordre.
brew update
brew install mongodb --devel
brew services start mongodb
puis créé un répertoire dans lequel le processus mongod écrira les données, ceci est facultatif car le processus mongod les prend par défaut, voir ce guide utile à https://docs.mongodb.com/manual/tutorial/install-mongodb-on-os -X/
sudo mkdir -p /data/db
Finalement commencé le processus mongod comme suit
sudo mongod
Oputput des commandes mongod (échoué) et sudo mongod (réussi) sur mon terminal.
