Javascript 无法连接到新的MongoDB Community Edition安装

我已经在上通过手动方式安装了mongoDB。 在终端中，我已检查状态，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）连接

$mongo

，它给了我以下错误：

连接响应包含错误：

有人能指导我如何解决这个问题吗
