我已经通过mongodb.com上的手册安装了mongoDB。 在终端中，我检查了状态，并且数据库正在运行：
Name Status User Plist
mongodb-community stopped
mongodb-community@3.6 stopped
mongodb-community@4.0 started vondramk /Users/vondramk/Library/LaunchAgents/homebrew.mxcl.mongodb-community@4.0.plist
尽管如此，我还是尝试（再次通过终端）与$ mongo连接，这给了我这个错误：
连接响应包含错误：
MongoDB shell version v4.2.1

有人可以指导我如何解决此问题吗？
