Question

我的Flask应用程序在localhost上运行顺畅，但在将其部署到heroku时无效。 heroku logs也没有提供太多信息错误。这是我的日志

`

我已经尝试了很多，但我无法弄清楚到底出了什么问题。你能帮我调试吗？

Answer 1

您的comprehensive_search模块未被推送到heroku。它可能尚未提交到您的本地git存储库。

你可以通过创建一个关闭bash dyno从heroku方面告诉：

heroku run bash

您将获得一个远程shell，您可以发出linux命令以查看模块代码是否符合您的预期。

从那里你可以确保你已经正确地检查了目录。

在Heroku上部署时，Flask app无法正常工作
