将 django 部署到谷歌云引擎服务器错误 (500)

Question

我一直在尝试使用 gcp 部署我的 django 项目，但我不断收到一系列错误。该项目在本地运行，但即使在gcloud app deploy 成功运行后也不会运行。如果我尝试访问该网站，我会得到server error (500) settings.py

if os.getenv('GAE_APPLICATION', None):
    
    DATABASES = {
        'default': {
            'ENGINE': 'django.db.backends.postgresql',
            'HOST': '/cloudsql/connection name',
            'USER': ' user',
            'PASSWORD': 'project_password',
            'NAME': 'instance name',
           
        }
    }
else:
   
    DATABASES = {
        'default': {
            'ENGINE': 'django.db.backends.postgresql',
            'NAME': 'portfolio',
            'USER': 'postgres',
            'PASSWORD': 'local db password',
            'HOST': 'localhost',
            'PORT': 5432,

        }
    }

AUTH_PASSWORD_VALIDATORS = [
    {
        'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator',
    },
    {'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator',
    },

STATIC_ROOT = os.path.join(PROJECT_DIR, 'static')
# STATICFILES_DIRS = (os.path.join(BASE_DIR, 'static'),)
MEDIA_URL = '/media/'

以下是错误日志中的错误报告 错误报告

如果我尝试进行一些更改，则会出现另一个错误

似乎它忽略了您的入口点。您可以尝试使用默认入口点。为此，您只需提供 main.py 文件。 该文件的内容如下所示：

from mysite.wsgi import application
# App Engine by default looks for a main.py file at the root of the app
# directory with a WSGI-compatible object called app.
# This file imports the WSGI-compatible object of the Django app,
# application from mysite/wsgi.py and renames it app so it is
# discoverable by App Engine without additional configuration.
# Alternatively, you can add a custom entrypoint field in your app.yaml:
# entrypoint: gunicorn -b :$PORT mysite.wsgi
app = application
