我刚完成我的第一个react应用程序，并且在此应用程序中，有一个由Algolia服务生成的搜索栏。因此，我需要创建一个应用程序来记录数据库中的每个更改（我使用Firebase）。因此，我遵循Algolia提出的this tutorial创建了此应用程序。在本地，当我运行我的应用程序时，一切正常。但是我需要在Heroku上部署此应用程序，并且在完成上传到Heroku之后，我使用命令行“ heroku open”，但是出现错误。因此，我在控制台中启动了命令行“ heroku logs --tail”，并进行了以下分析：

这似乎是由于我与firebase的连接失败，尽管我已经在.env文件中指定了路径，并且直接在Heroku中通过指定变量来指定路径（有疑问...）
这是我第一次尝试在Heroku中上传应用。不知道可以帮我吗？
答案 0 :(得分：0)
可以是任何东西，但很可能是以下原因：
您在本地环境中使用的process.ENV变量在Heroku中不起作用。
在Heroku中，您必须设置所有process.ENV变量，如下所示：
heroku config:set FIREBASE_DATABASE_URL='https://abcd.firebaseio.com'
如果您有更多process.ENV变量，则可以在末尾设置所有添加空间：
heroku config:set FIREBASE_DATABASE_URL='https://abcd.firebaseio.com' FIREBASE_API_KEY: '1234' FIREBASE_AUTH_DOMAIN: 'abc'
或者您可以在Heroku仪表板中完成它：
同时查看this Heroku web-page。
