1、使用brew安裝mongodb需要先更新brew
brew update
如果更新時抱如下錯誤：
yindengxu@xuyindengdeMacBook-Pro ~ % brew update
Error:
homebrew-core is a shallow clone.
To `brew update`, first run:
git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow
This restriction has been made on GitHub's request because updating shallow
clones is an extremely expensive operation due to the tree layout and traffic of
Homebrew/homebrew-core and Homebrew/homebrew-cask. We don't do this for you
automatically to avoid repeatedly performing an expensive unshallow operation in
CI systems (which should instead be fixed to not use shallow clones). Sorry for
the inconvenience!
根據提示執行如下命令：
git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow
運行結果如下圖所示：
yindengxu@xuyindengdeMacBook-Pro ~ % git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow

3、執行如下命令：
brew install mongodb-community
運行結果如下圖所示：
yindengxu@xuyindengdeMacBook-Pro ~ % brew install mongodb-community

Error: Your CLT does not support macOS 11.
It is either outdated or was modified.
Please update your CLT or delete it if no updates are available.
Update them from Software Update in System Preferences or run:
softwareupdate --all --install --force
If that doesn't show you an update run:
sudo rm -rf /Library/Developer/CommandLineTools
sudo xcode-select --install
Alternatively, manually download them from:
https://developer.apple.com/download/more/.
Error: An exception occurred within a child process:
SystemExit: exit
根據提示執行如下命令：
softwareupdate --all --install --force
運行結果如下：
yindengxu@xuyindengdeMacBook-Pro ~ % softwareupdate --all --install --force
Software Update Tool
Finding available software
No updates are available.
繼續執行如下命令：
sudo rm -rf /Library/Developer/CommandLineTools
sudo xcode-select --install
需要輸入密碼,彈出安裝插件框，確定安裝，運行結果如下：
yindengxu@xuyindengdeMacBook-Pro ~ % sudo rm -rf /Library/Developer/CommandLineTools
sudo xcode-select --install

xcode-select: note: install requested for command line developer tools
4、安裝之后，需要創建一個/data/db文件夾用來作為默認數據庫目錄。執行以下步驟：
sudo mkdir -p /data/db
因為Mac電腦默認是開啟安全模式的，不能在根目錄下面隨便創建刪除文件夾。所以我們創建的時候，會報這個錯誤mkdir: /data/db: Read-only file system，如下：
yindengxu@xuyindengdeMacBook-Pro ~ % sudo mkdir -p /data/db
mkdir: /data/db: Read-only file system
更改為在用戶更目錄下創建數據庫默認目錄
mkdir ~/data
進入剛剛創建的目錄：
cd ~/data
查看目錄路徑，下面會用到:
pwd
運行結果：
/Users/yindengxu/data
指定MongoDB數據庫路徑,這里的路徑需要換成你自己電腦上面的路徑
sudo mongod --dbpath=/Users/yindengxu/data
5、執行如下命令：
sudo chown ‘username’ /data/db
6、mongodb啟動和停止
brew services start mongodb-community
brew services stop mongodb-community
