Zappa 部署错误 - 对流层==2.7.1 没有帮助 AttributeError：“模板”对象没有属性“add_description”

我已将 python 项目从 2.7 迁移到 3.8。我正在尝试使用 zappa 进行部署。 但是，一旦开始更新 Lambda 函数配置，就会遇到此错误。

Updating Lambda function configuration..
Oh no! An error occurred! :(

==============

我发现了这个问题并尝试按照此建议降级对流层post https://stackoverflow.com/questions/68391621/zappa-deploy-fails-with-attributeerror-template-object-has-no-attribute-add但我再次面临一个新错误，如下所示：

非常感谢任何想法/帮助。 谢谢

setuptools58 打破了对的支持use_2to3。因此，您应该添加setuptools<58到您的需求文件以及troposphere<3。如果仍然遇到同样的问题，请先降级 setuptools，然后安装符合其他要求的对流层。
