在Heroku上举帆应用程序失败

Question

我无法在Heroku上的生产环境中使用Sails应用程序来连接到mongolab。当在本地设置中运行时，这很好。Heroku日志显示了以下..。

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

`

运行风帆0.11.2版

船帆-蒙戈版本0.11.4

添加和验证了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
`

package.json

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

models.js已设置为

`
 connection: 'mongodb',
`

因此，对本地mongolab和远程mongolab的连接都可以在本地运行，但对Heroku的部署失败。让我看看我是不是错过了什么东西。对此表示感谢。

Answer 1

我通过使用船帆-蒙戈的主版本来解决这个问题。

package.json

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

然后，一旦部署到heroku，就会重新启动dyno

`heroku ps:scale web=1`

Answer 2

已知的窃听器。查看https://github.com/balderdashy/sails-mongo/issues/352

您可能需要npm install sails-mongo#master --save，直到它发布。

Answer 3

对于那些在heroku部署后被接受的答案不起作用的人，请尝试更改节点js、sails mongo版本以及sails和check。

在将版本更改为下面的版本后，它对我有效：

1.nodejs - 14.15.1

2.帆- ^1.5.2

3.帆-芒果- ^2.0.0
