在 Heroku 上提升风帆应用程序失败

Question

我无法在 Heroku 的生产环境中提升 Sails api 应用程序以连接 mongolab 数据库。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process.env个变量

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'
}
`

过程文件

`
web: npm start
`

package.json

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

models.js 已设置为

`
 connection: 'mongodb',
`

因此，运行这在本地可以很好地连接到本地 mongo 数据库和远程 mongolab 数据库，但部署到 Heroku 失败。在我看来，我在设置中遗漏了一些东西。对此表示感谢。

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

我使用 sails-mongo 的主版本解决了这个问题。

package.json

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

然后部署到 heroku 后用

重新启动测功机

`heroku ps:scale web=1`

Answer 3

如果在 heroku 中部署后接受的答案不起作用，请尝试更改节点 js、sails-mongo 版本以及 sails 并检查。

将版本更改为以下后对我有用：

1.nodejs - 14.15.1

2.sails - ^1.5.2

3.sails-mongo - ^2.0.0
