用了morgan打印出来的东西和老师的不一样为啥？

Question

结果：    Mongoose: users.ensureIndex({ name: 1 }) { unique: true, background: true, safe: undefined }var logger = require('morgan')if ('development' === app.get('env')) { app.set('showStackError',true) app.use(logger(':method :url :status')) app.locals.pretty = true mongoose.set('debug',true)};
