【问题讨论】：

您有两个错误。首先查看 package.json 并找到 grunt-node-inspector 依赖项。其次，您的 mongodb 服务未运行或未安装。
固定 MongoDB 没有安装哈哈哈哈哈哈哈！！！！！！！！！

标签： node.js mongodb gruntjs

【解决方案1】：

mongodb 没有安装。

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10

echo "deb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.0.list 

sudo apt-get update 

sudo apt-get install -y mongodb-org
