Derby.js出现Derby Auth错误

Question

I just start with Derby and started out with integrating MongoDB and derby-auth. However, I am having troubles with that and can't figure it out. The following code returns the stacktrace below it. Finding out what causes the error is really hard. This is a new project generated with derby -c new project. All I know is that it's related to the auth.store(store) line.

UPDATE : I am also having this problem with the example/ in derby-auth, but only on my first request so I guess it would be relate to the database connection.

http = require 'http'
path = require 'path'
express = require 'express'
gzippo = require 'gzippo'
derby = require 'derby'
app = require '../app'
serverError = require './serverError'
auth = require('derby-auth')
MongoStore = require('connect-mongo')(express)


## SERVER CONFIGURATION ##

expressApp = express()
server = http.createServer expressApp

derby.use(require 'racer-db-mongo')
derby.use(derby.logPlugin)
store = derby.createStore
  listen: server
  db:
    type: 'Mongo'
    uri: 'mongodb://localhost/admin'

module.exports = server
auth.store(store)

ONE_YEAR = 1000 * 60 * 60 * 24 * 365
root = path.dirname path.dirname __dirname
publicPath = path.join root, 'public'

# Authentication strategies (providers actually)
strategies =
  facebook:
    strategy: require('passport-facebook').Strategy
    conf:
      clientID: 'boo'
      clientSecret: 'boo'

# Authentication optionss
options =
  domain: (if process.env.NODE_ENV is 'production' then "http://www.mydomain.com" else "http://localhost:3000" )

expressApp
  .use(express.favicon())
  # Gzip static files and serve from memory
  .use(gzippo.staticGzip publicPath, maxAge: ONE_YEAR)
  # Gzip dynamically rendered content
  .use(express.compress())

  # Uncomment to add form data parsing support
  .use(express.bodyParser())
  .use(express.methodOverride())

  # Uncomment and supply secret to add Derby session handling
  # Derby session middleware creates req.session and socket.io sessions
  .use(express.cookieParser())
  .use(store.sessionMiddleware
    secret: 'mooo'
    cookie: {maxAge: ONE_YEAR}
    store: new MongoStore({ url: 'mongodb://localhost/admin' })
  )

  # Adds req.getModel method
  .use(store.modelMiddleware())

  # Authentication
  .use(auth.middleware(strategies, options))

  # Creates an express middleware from the app's routes
  .use(app.router())
  .use(expressApp.router)
  .use(serverError root)


## SERVER ONLY ROUTES ##

expressApp.all '*', (req) ->
  throw "404: #{req.url}"

Answer 1

在$ derbypath / lib / app / index.js：18：11中检查此行
