EB Django配置命令错误

Question

几天来，我一直试图在EB上部署django应用程序，但运行命令时一直遇到错误。因此，基本上，当我尝试部署应用程序时，它会给我"python:无法打开文件‘manage.py e.py’：Errno 2--没有这样的文件或目录。“对于完全错误，这是在我的终端上运行eb deploy之后得到的结果。

下面是我拥有的配置文件：

option_settings:
    "aws:elasticbeanstalk:application:environment":
        DJANGO_SETTINGS_MODULE: "hungryboat.settings"
        PYTHONPATH: "./hungryboat"
    "aws:elasticbeanstalk:container:python":
        WSGIPath: "hungryboat/wsgi.py"
        NumProcesses: 3
        NumThreads: 20
    "aws:elasticbeanstalk:container:python:staticfiles":
        "/static/": "www/static/"

commands:

    01_pip_update:
        command: "pip install --upgrade pip"
        leader_only: true
    02_pip_freeze:
        command: "pip freeze > requirements.txt"
    03_migrate:
        command: "source /opt/python/run/venv/bin/activate && python manage.py migrate --noinput"
        leader_only: true
    04_collect_static:
        command: "source /opt/python/run/venv/bin/activate && python manage.py collectstatic --noinput"

我曾尝试将项目名称放在manage.py前面，但仍然给出了相同的错误。我不知道我怎么能解决这个问题。请救救这个可怜的灵魂。谢谢。

编辑：项目目录树看起来或多或少如下所示：

**编辑:修复了上面的问题，但现在我遇到了不同的错误**

在settings.py里面，

SECRET_KEY = os.environ['APP_SECRET_KEY']

但是我得到了这个错误

INFO: Deploying new version to instance(s).                         
ERROR: [Instance: i-0c46f0a9e5069d5bf] Command failed on instance. Return code: 1 Output: (TRUNCATED)...python/run/venv/local/lib/python3.4/site-packages/django/conf/__init__.py", line 116, in __init__
raise ImproperlyConfigured("The SECRET_KEY setting must not be empty.")
django.core.exceptions.ImproperlyConfigured: The SECRET_KEY setting must not be empty.

我在EB环境变量中有APP_SECRET_KEY。

option_settings:
  "aws:elasticbeanstalk:application:environment":
     DJANGO_SETTINGS_MODULE: "hungryboat.settings"
     PYTHONPATH: "/opt/python/current/app/hungryboat:$PYTHONPATH"
  "aws:elasticbeanstalk:container:python":
     WSGIPath: "hungryboat/wsgi.py"
     NumProcesses: 3
     NumThreads: 20
  "aws:elasticbeanstalk:container:python:staticfiles":
     "/static/": "www/static/"

container_commands:
  01_migrate:
    command: "django-admin.py migrate"
    leader_only: true
  02_collect_static:
    command: "python /opt/python/current/app/hungryboat/manage.py collectstatic --noinput"

您的pythonpath是错误的，这就是为什么它找不到manage.py文件。首先更改pythonpath，然后再试一次。还要确保您在本地项目上有一个requirements.txt。您不应该在实例中创建需求，您应该在本地创建，并且在部署时，它将使用pip安装需求中的所有包。
