Heroku Node.js错误，代码=H10，描述="应用程序崩溃"。

node.jsheroku
3

我翻了很多类似的主题，但至今无法解决我的问题。

我创建了一个MERN应用程序，使用了亚马逊作为我的资产，并尝试在Heroku上部署它。

我的应用程序在本地工作正常，但当我在Heroku上部署它时，出现了“应用程序错误”。 当我查看heroku logs --tail时，这是我得到的最终错误：

2019-04-27T12:49:01.084214+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=calm-earth-15269.herokuapp.com request_id=b2953cc1-6894-4697-8fc4-17d5012c536e fwd="93.11.10.123" dyno= connect= service= status=503 bytes= protocol=https

我已经尝试/检查过以下内容：

  • 端口
const port = process.env.PORT || 5000;

app.listen(port, () => console.log(`Joystock Server running on port ${port}`));

  • 尝试执行命令：heroku restart

  • 在我的package.json文件中添加引擎版本信息

"engines": {
    "node": "8.12.0",
    "npm": "6.4.1"
  },

  • 我的配置变量（mongoURI）已在此应用的Heroku设置中正确定义。

  • 我还尝试完全重建这个应用程序，从头开始，一切都是最新的。

  • 起初，对于'/'没有定义路由，所以我尝试在routes/tracks.js中添加一个路由。

router.get('/', (req, res) => {
  res.redirect('/all/page-1');
});

无论是否使用该路线，我得到的结果都是相同的。 ......我总是遇到相同的错误。
这是我当前应用程序的git存储库： https://github.com/Karaza/joystock
我已经没有想要尝试修复我的应用程序的想法了。
提前感谢您的帮助(:
我认为这部分已经很容易理解了：确保mongoose.connect()或mongoose.createConnection()的第一个参数是一个字符串。 - Lissy93

在文件：joystock/config/keys.js 中... 确保 NODE_ENV 是 production？没有 keys_dev 文件。

if (process.env.NODE_ENV === 'production') {
    module.exports = require('./keys_prod');
} else {
    module.exports = require('./keys_dev');
}

我不熟悉Heroku，但看起来你禁用了生产模式。

"heroku-postbuild": "NPM_CONFIG_PRODUCTION=false npm install --prefix client && npm run build --prefix client"

所以我认为需要检查：

process.env.MONGO_URI
process.env.NODE_ENV
文件“keys_dev.js”存在，我只是没有将其推送到git，因为我不想显示我的mongoDB URI。 “NPM_CONFIG_PRODUCTION=false”应该只影响devdependecies的安装（更多信息请参见：https://devcenter.heroku.com/articles/nodejs-support#customizing-the-build-process） - Kara
@Kara，无论如何，我认为需要在server.js中记录“db”，看起来它是未定义的。 - Tim Times
哦天啊...就是这个问题...我在Heroku的变量设置中打成了mongoURI而不是MONGO_URI！ 现在它可以工作了 (: - Kara

在我的配置变量中，我尝试定义mongoURI而不是MONGO_URI。 现在它可以工作了 :)
