Procfile 内容是

最佳答案
我认为您还没有发布实际的 wsgi.py 文件。您得到的异常来自 whitenoise，但您发布的文件使用 dj_static。
为避免错误，您需要确保行:
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "proyecto_www.settings.staging")
在导入 whitenoise.django 之前出现。
这是由于 Django 中的一个错误，将在以后的版本中修复。
关于python - 使用 Django 1.8 部署时出现应用程序错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/34829487/
