Question

我无法在Heroku的生产环境中解除Sails api应用程序以连接mongolab db。这在本地设置中运行时效果很好。 Heroku日志显示以下内容......

`
/app/node_modules/mongodb/lib/server.js:235
        process.nextTick(function() { throw err; })
                                      ^

运行风帆版本0.11.2

Sails-mongo版本0.11.4

已添加并验证了process.env变量

connection.js

`
mongodb: {
  adapter: 'sails-mongo',
  url : process.env.CONNECTION_URL,
  host: process.env.DB_HOST,
  port: process.env.PORT_NR,
  user: proces.env.USER,
  password: process.env.PASSWORD,
  database: process.env.DB
},

` ENV / production.js

`
connections : {
  mongoLive: {
    adapter: 'sails-mongo',
    url : process.env.CONNECTION_URL
  }
},
models: {
  connection: 'mongoLive'
},
`

development.js

`
connections : {
  mongoDev: {
    adapter: 'sails-mongo',
    host: 'localhost',
    port: 27017,
    database: 'threads_db'
  }
},

models: {
  connection: 'mongoDev'
}
`

Procfile

`
web: npm start
`

的package.json

`
"scripts": {
  "debug": "node debug app.js",
  "start": "sails lift"
},
`

models.js已设置为

`
 connection: 'mongodb',
`

因此，在本地运行它可以正常工作，同时连接到本地mongo db和远程mongolab db，但部署到Heroku失败。看到我在设置中遗漏了一些东西。对此有所帮助。

Answer 1

已知错误。查看https://github.com/balderdashy/sails-mongo/issues/352

在发布之前，您可能需要npm install sails-mongo#master --save。

Answer 2

我通过使用sails-mongo的主版本解决了这个问题。

的package.json

"sails": "git+https://github.com/balderdashy/sails.git"

然后一旦部署到heroku，用

重新启动dyno

`heroku ps:scale web=1`

在Heroku上提升风帆应用失败了
