用Node.js安装混淆MongoDB

我正在尝试首次安装一个节点/ mongo应用程序，特别是https://github.com/nature/pa11y-dashboard到我的Digital Ocean Ubuntu液滴上的虚拟主机。

我已经成功安装了所有的依赖项，但我不确定MongoDbconfiguration。 在/ config目录中有一个development.json示例，说明似乎暗示在本地使用是很好的。

{ "port": 4000, "noindex": true, "readonly": false, "webservice": { "database": "mongodb://localhost/pa11y-webservice-dev", "host": "0.0.0.0", "port": 3000, "cron": "0 30 0 * * *" } 

}

运行NODE_ENV=development nodejs . 输出以下错误。

 connect.multipart() will be removed in connect 3.0 visit https://github.com/senchalabs/connect/wiki/Connect-3.0 for alternatives connect.limit() will be removed in connect 3.0 pa11y-dashboard started mode: development uri: http://0.0.0.0:4000 pa11y-webservice started mode: development uri: http://0.0.0.0:3000 /var/www/website.com/public/node_modules/pa11y-webservice/node_modules/mongodb/lib/mongodb/connection/base.js:242 throw message; ^ TypeError: undefined is not a function at __executeInsertCommand (/var/www/website.com/public/node_modules/pa11y-webservice/node_modules/mongodb/lib/mongodb/db.js:1829:12) at Db._executeInsertCommand (/var/www/website.com/public/node_modules/pa11y-webservice/node_modules/mongodb/lib/mongodb/db.js:1930:5) at /var/www/website.com/public/node_modules/pa11y-webservice/node_modules/mongodb/lib/mongodb/db.js:1442:27 at /var/www/website.com/public/node_modules/pa11y-webservice/node_modules/mongodb/lib/mongodb/db.js:1560:7 at /var/www/website.com/public/node_modules/pa11y-webservice/node_modules/mongodb/lib/mongodb/cursor.js:162:16 at commandHandler (/var/www/website.com/public/node_modules/pa11y-webservice/node_modules/mongodb/lib/mongodb/cursor.js:706:16) at /var/www/website.com/public/node_modules/pa11y-webservice/node_modules/mongodb/lib/mongodb/db.js:1806:9 at Server.Base._callHandler (/var/www/website.com/public/node_modules/pa11y-webservice/node_modules/mongodb/lib/mongodb/connection/base.js:442:41) at /var/www/website.com/public/node_modules/pa11y-webservice/node_modules/mongodb/lib/mongodb/connection/server.js:485:18 at MongoReply.parseBody (/var/www/website.com/public/node_modules/pa11y-webservice/node_modules/mongodb/lib/mongodb/responses/mongo_reply.js:68:5) 

看着Mongo shell没有分贝为pa11y-webservice-dev显示，但从我读的是典型的，直到数据被推到那里。

任何帮助获得这一设置将不胜感激！
