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

# accessible through os.environ['VARIABLE_NAME']

  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

#manual_scaling:

在我的 settings.py 中WSGI_APPLICATION = 'rec.wsgi.application'即使我将其更改为 WSGI_APPLICATION = 'wsgi.application'
它没有解决，错误仍然存​​在。

我已经尝试使用 main:app 编辑入口点，问题是一样的....有人请解决这个问题。谢谢

通常可能有 2 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。我在使用旧版本的 gunicorn 时遇到了同样的问题。

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，应用程序将在没有安装所有包的情况下进行部署，这在部署到 GAE 时不会返回任何错误。
