【问题描述】：
我正在尝试在我的 Mac 上安装 mongoDB。但是，我遇到了很多问题。
我首先使用 Homebrew 通过运行以下命令安装了 mongoDB：
brew tap mongodb/brew
brew install mongodb-community@4.2
然后使用：
brew services start mongodb-community@4.2
此时一切看起来都很好，直到我尝试在终端中运行：
mongod
一开始我以为问题是我没有创建 /data/db 文件夹，所以我跑了：
sudo mkdir -p /data/db
这不起作用。
然后我找到一篇文章说Mac用户需要运行：
sudo mkdir -p /System/Volumes/Data/data/db
这行得通..然后我跑了：
mongod --dbpath /System/Volumes/Data/data/db
并收到以下信息：

我试过跑步：
sudo chown -Rv user /System/Volumes/Data/data/db
mongod
然后收到如下：

对于 SocketException，我试过了：
mongod --port 27018
并收到：

我似乎无法弄清楚发生了什么，因为我只是按照我在 StackOverflow 上从其他人那里找到的所有步骤来解决这个问题。

我对自制软件不熟悉。我认为您正在尝试很多事情，有些正在起作用，有些不起作用（尚不清楚什么是什么不是）。 MongoDB 数据库需要一次成功安装和一次成功启动。一旦成功启动，就可以使用 Mongo Shell 或 MongoDB Compass 等工具访问。这里是general instructions on installing. starting and accessing MOngoDB on MacOS。

也不熟悉 brew 但听起来好像一旦你运行
brew services start它就已经启动了'mongod'，这就是为什么当再次尝试运行它时它会显示“地址已在使用中”。而是使用默认地址的“mongo”或指南针连接到已经运行的实例。在终端中尝试运行“mongo”，它应该可以连接。
