Если вы уже установили MongoDB, сначала попробуйте запустить mongod от имени пользователя sudo, я столкнулся с проблемой из-за того, что mongod не запускался в качестве суперпользователя.
Я вставил o / p для обеих команд ( mongod и sudo mongod ) в самом низу, вы тоже можете это проверить, но
Сначала попробуйте это
sudo mongod
не этот
mongod
Я установил MongoDB на свой MAC OS X Sierra 10.12.6, последовательно выполнив следующую команду.
brew update
brew install mongodb --devel
brew services start mongodb
затем создал каталог, в который процесс mongod будет записывать данные, это необязательно, поскольку процесс mongod принимает его по умолчанию, см. это полезное руководство по адресу https://docs.mongodb.com/manual/tutorial/install-mongodb-on-os -Икс/
sudo mkdir -p /data/db
Наконец, начал процесс mongod следующим образом
sudo mongod
Вывод команд mongod (сбой) и sudo mongod (успешно) на моем терминале.
