为什么 Docker Django 管理员崩溃并显示代码 245

我正在 OSX 10.15.3 上使用 runserver 运行 Django 版本 3.0.3。我的应用程序没问题，但是当我尝试访问http://localhost:8000/admin/时，容器崩溃并显示“exited with code 245”，Docker 日志中没有更多内容，看起来像 python 问题，知道如何调试。感谢 Dokerfile ：

编辑：经过一些调试，问题似乎来自 django/django/core/handlers/base.py 143 response = response.render()

也许是因为循环第 132 行的 self._template_response_middleware 为空

编辑2：

MIDDLEWARE = [
    'debug_toolbar.middleware.DebugToolbarMiddleware',
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',

编辑3：似乎没有调用 load_middleware base.py(23) ，因此 self._template_response_middleware 为空。当我使用 localhost:8000 访问我的应用程序时，一切工作正常，问题仅针对 localhost:8000/admin。我用打印进行调试，这是更好的方法吗？我尝试 Pdb 但没有成功，Werkzeug 在这种情况下什么也没给出。
