【问题描述】：
在我的 Mac 上安装 Ruby 时，我关注了 this setup。据我了解，我通过 Homebrew 安装了 Ruby，这在我的机器上似乎运行良好，而且我不需要在每个命令前加上 sudo。
我现在正在尝试安装 MongoDB，并已使用 brew install mongodb 安装它。我认为它现在已安装，因为当我运行 mongo --version 时它会返回：
MongoDB shell version: 2.6.4
现在我正在尝试启动一个普通的应用程序，但是当我在根目录中运行 grunt 时，它会停止并抛出此错误：
Error: failed to connect to [localhost:27017]
**Could not connect to MongoDB. Please ensure mongod is running and restart MEAN app.**
我想知道这是否与我的 $PATH 有关，这让我感到困惑......？
当我运行which ruby 时，会出现这条路径：
/Users/xxx/.rbenv/shims/ruby
当我运行which mongo 时，会出现这条路径：
/usr/local/bin/mongo
这可能是为什么它说无法连接到 MongoDB，我是否正确安装了它？
我只是希望能够启动那个 MEAN 应用程序，但 MongoDBV 安装似乎有问题。
这是我运行mongod时遇到的错误：
mongod --help for help and startup options
