我尝试在Heroku上部署一个Web应用程序，并使用Dash制作的应用程序。我已经成功地在Heroku上部署了几个示例应用程序，并且我已经成功地在本地服务器上部署了我的应用程序。当我尝试在Heroku上部署我自己的应用程序时，问题出现了。我已经尝试了几种不同的方法在Heroku上部署，但尽管成功构建，我仍然继续得到“应用程序错误”。我已经包括了我的日志，但可以使用帮助了解他们。我仍然是相当新的这一点，所以任何见解将不胜感激。

缺少'dash_table_experiments'，需要将其添加到requirements.txt git add A- git commit -m 'modifications'

安装完丢失的模块后，您需要重新创建requirements.txt文件，其中包含：

pip freeze > requirements.txt

然后提交新的更改并部署。

你应该创建一个runtime.txt文件，并指出你在安装这些依赖时使用的Python。
