python - foreman 未启动名为 myapp 的模块

Question

我在这里遵循heroku快速入门指南: https://devcenter.heroku.com/articles/getting-started-with-python

我被困在工头开始部分。这就是我的目录的样子。我只是运行一个基本的网络应用程序。没有框架或任何东西。

soapbar/
    Procfile.txt
    soapbar/
        soapbar.py
    venv/
        Include/
        Lib/
        Scripts/ 

这是堆栈跟踪:

有什么想法吗？

将名为 __init__.py 的文件添加到 soapbar/ 文件夹中。将其留空。

The __init__.py files are required to make Python treat the directories as containing packages; this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later on the module search path. In the simplest case, __init__.py can just be an empty file, but it can also execute initialization code for the package or set the __all__ variable.
