使用Zappa将Django应用实例化为lambda函数时，出现以下错误。

我尝试使用在本地运行应用程序

python manage.py runserver

，并且在本地运行良好。但是，将应用程序部署到lambda函数时，出现上述错误。

我正在使用Django 2.0.10，Python 3.6和AWS Aurora RDS。

我希望lambda函数实例不会出错，就像在本地一样。

在部署后调用zappa以保留打包的zip，并检查文件夹结构或尝试从该文件夹运行项目。

您是否将Django添加到需求文件中？我记得Zappa从全新的虚拟环境重建了lambda软件包，安装了requirements.txt并应用了您的文件夹。

或仔细检查cloudwatch日志中是否存在导入错误。仅在部署后刷新容器时才会显示导入错误，而导入错误不会在每次lambda调用时都显示。

使用Zappa部署Django应用时导入错误？
