这是/.ebextensions/django.config 文件:

option_settings:
 "aws:elasticbeanstalk:application:environment":
     DJANGO_SETTING_MODULE: "ecs_site.settings"
     PYTHON_PATH: "/opt/python/current/ecs_site/ecs_site:$PYTHONPATH"
 "aws:elasticbeanstalk:container:python":
     WSGIPath: "ecs_site/ecs_site/wsgi.py"

这是我的 wsgi.py 文件(仅供引用):

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "ecs_site.settings")

application = get_wsgi_application()

这里是manage.py:

import os
import sys

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "ecs_site.settings")
    try:
        from django.core.management import execute_from_command_line
    except ImportError:
        # The above import may fail for some other reason. Ensure that the
        # issue is really that Django is missing to avoid masking other
        # exceptions on Python 2.
        try:
            import django
        except ImportError:
            raise ImportError(
                "Couldn't import Django. Are you sure it's installed and "
                "available on your PYTHONPATH environment variable? Did you "
                "forget to activate a virtual environment?"
            )
        raise
    execute_from_command_line(sys.argv)

Answer 1

django.config 文件中的 PYTHONPATH 设置似乎太深了。第二级ecs_site目录是一个包，因此PYTHONPATH应该指向上面的目录，以便ecs_site.settings模块可以已解决:

PYTHONPATH: "/opt/python/current/ecs_site:$PYTHONPATH"

此外，请确保变量名为 PYTHONPATH 而不是 PYTHON_PATH。
