我正在尝试使用django部署网站/ webapp ...构建了app.yaml和Requirements.txt ...一切都完成了，当我点击gcloud app deploy时，最后出现了以下错误日志。

这是我的app.yaml

runtime: python

api_version: 1
threadsafe: true

# the PROJECT-DIRECTORY is the one with settings.py and wsgi.py
entrypoint: gunicorn -b :$PORT ~/NovUs/rec/rec.wsgi
# specific to a GUnicorn HTTP server deployment
env: flex 
# for Google Cloud Flexible App Engine

# any environment variables you want to pass to your application.
# accessible through os.environ['VARIABLE_NAME']
env_variables:
# the secret key used for the Django app (from PROJECT-DIRECTORY/settings.py)
  SECRET_KEY: '***i removed this***' 
  DEBUG: 'False' # always False for deployment

# everything after /cloudsql/ can be found by entering >> gcloud sql instances describe DATABASE-NAME << in your Terminal

在我的settings.py中 WSGI_APPLICATION = 'rec.wsgi.application' 即使我将其更改为WSGI_APPLICATION = 'wsgi.application'也无法解决，错误仍然保持不变。

并且我尝试用main:app编辑入口点，问题是一样的...。有人请解决这个问题。谢谢

Answer 1

在您的app.yaml中，添加默认的gunicorn入口点行，但还要添加更长的超时时间以满足您的需要：entrypoint: gunicorn -b :$PORT YOURSITE.wsgi --timeout 120

Answer 2

通常可能存在两个问题，前一段时间在Google App Engine上部署Dash应用程序时遇到了这个问题。

GAE的gunicorn版本可能存在版本冲突。请改用Gunicorn 19.7.1或更高版本。使用旧版本的Gunicorn时，我遇到了同样的问题。

另一个冲突可能是requirements.txt与main.py入口点不在同一目录中。因此，该应用将在未安装所有软件包的情况下进行部署，部署到GAE时不会返回任何错误。

使用python + django + gunicorn的Gcloud应用程序部署失败+工作程序无法启动
