我只是想创建一个超级用户，以便我可以登录到我网站的管理部分。到目前为止，其他一切都在工作。这是我的活动错误日志的相关部分：

我正在尝试通过 db-migrate.config 文件进行部署：

container_commands:
  01_migrate:
    command: "django-admin.py migrate"
    leader_only: true
  02_createsuperuser:
    command: "echo \"from users.models import UserProfile; UserProfile.objects.create_superuser(xxxxxxx@gmail.com', 'passxxxword')\" | /opt/python/run/venv/bin/python /opt/python/current/app/manage.py shell"
    leader_only: true
option_settings:
  aws:elasticbeanstalk:application:environment:
    DJANGO_SETTINGS_MODULE: studyspot.settings

【问题讨论】：

您尝试通过shell 管理命令而不是createsuperuser 管理命令执行此操作是否有特殊原因？
这是一个自定义用户模型，我不知道还有其他方法，因为它确实需要在 manager.py 中实现 create_superuser
只要设置了DJANGO_SETTINGS_MODULE和settings.AUTH_USER_MODEL，使用createsuperuser应该没问题。
django 用户模型的重点不是让所有用户，包括同一个用户表中的超级用户吗？
没有关注？只要设置正确，createsuperuser 应该在您的自定义用户表中创建用户。

【解决方案1】：

Elastic beanstalk 终于在 db-migrate.config 文件中使用了我的超级用户命令：

02_createsuperuser:
command: "echo \"from django.contrib.auth import get_user_model; User = get_user_model(); User.objects.create_superuser('xxxxx@gmail.com', 'xxxxxpasword')\" | python manage.py shell"

这是使用自定义用户模型，目前没有太多关于此的信息，所以我希望这对某人有所帮助。我没有在此处包含managers.py 文件，但该部分应该很简单，而且我确实必须确保在我的forms.py 文件中的用户创建表单中具有保存用户功能。这花了我一周的时间才弄清楚，所以我将其发布以帮助其他人。

【解决方案2】：

对于这不起作用的任何人，您可以尝试以下方法（适用于部署在 AWS EB Linux 2/3.3.1 上的 python 3.8.5 环境中的 Django 3.0.6）。我使用 PostgreSQL。

这是适用于我的 db-migrate.config 文件的完整内容（2021 年）。

首次部署：

container_commands:
  01_migrate:
    command: "source /var/app/venv/*/bin/activate && python3 manage.py migrate && django-admin.py migrate"
    leader_only: true

  02_createsuperuser:
    command: "source /var/app/venv/*/bin/activate && echo \"from django.contrib.auth.models import User; User.objects.create_superuser('ADMIN_NAME', 'EMAIL', 'PASSWORD')\" | python3 manage.py shell"
    leader_only: true

option_settings:
  aws:elasticbeanstalk:application:environment:
    DJANGO_SETTINGS_MODULE: ebdjango.settings

每隔一段时间（必须更改，否则会出错）。请注意，“django-admin.py migrate”已经消失了：

container_commands:
 01_migrate:
     command: "source /var/app/venv/*/bin/activate && python3 manage.py migrate"
        leader_only: true
    
    option_settings:
      aws:elasticbeanstalk:application:environment:
        DJANGO_SETTINGS_MODULE: ebdjango.settings

（抱歉，空格有点不对 - 所以只需复制粘贴更正它）

您需要了解部署在 EC2 实例上的 python 环境实际上是 python2。而python3系统环境（我认为）是3.6还是3.7？因此，您必须激活您在 django 部署中使用的 python venv。那是在 /var/app/venv/*/bin/...

您可以通过 SSH 方式检查您的 EC2 实例并在那里进行测试。我认为 Python2 仍然是大多数 linux 机器的默认 python。除非您另有说明，否则即使 Ubuntu 18 也默认使用 Python2。您可以简单地检查各种 Python 版本。但在任何情况下，您都必须像上面的代码那样获取正确的环境。否则这是行不通的。

祝你好运！希望 AWS 可以在不久的某个时候更新他们的文档。
