【MAC安装Mongo】安装mongodb的时候报错，
Error: No available formula with the name "mongodb"
==> Searching for a previously deleted formula (in the last month)...
Warning: homebrew/core is shallow clone. To get complete history run:
git -C "$(brew --repo homebrew/core)" fetch --unshallowError: No previously deleted formula found.

设定:brew install mongodb-community@4.2
启动：$ brew services start mongodb-community
