node.js – 找不到MongoDB数据/ db

/usr/local/Cellar/mongodb/3.2.6/data/db

执行以下步骤以创建绑定到mongodb文件夹

sudo mongod --directoryperdb --dbpath /usr/local/Cellar/mongodb/3.2.6/data/db --logpath /usr/local/Cellar/mongodb/3.2.6/log/mongodb.log --logappend -rest

在终端中初始化sudo mongod时,会出现以下错误：

你能解释一下有什么问题吗？为了与MongoDB一起正常工作,你可以展示一些常见的做法吗？

要么你需要使用sudo,例如sudo mkdir -p / data / db

或者你需要做su – 成为超级用户,然后使用mkdir -p / data / db创建目录
