AWS Beanstalk - FileNotFoundError：[Errno 2] 没有这样的文件或目录：'/var/app/staging/'

Question

我使用的是没有容器的 Elastic Beanstalk，仅使用 EC2 实例。有时创建新实例时会无故失败。我发现了一些奇怪的日志

FileNotFoundError: [Errno 2] No such file or directory: '/var/app/staging/'

我知道该文件夹的内容包含我的代码的新版本，但我不管理该文件夹，它是由AWS本身通过cloudformation管理的。有什么解决办法吗？

谢谢

解决启动时没有问题的问题:)

如果它是 django 应用程序，您可能需要在 .ebextension 文件中配置类似的内容。 app_core 是包含您的settings.py 文件的目录

option_settings:
  aws:elasticbeanstalk:application:environment:
    DJANGO_SETTINGS_MODULE: "dtp_web_core.settings"
    PYTHONPATH: "/var/app/current:$PYTHONPATH"
  aws:elasticbeanstalk:container:python:
    WSGIPath: "dtp_web_core.wsgi:application"
  aws:elasticbeanstalk:environment:proxy:staticfiles:
    /static: staticfiles
