我没有得到任何错误在本地与节点获取包。json也有节点获取依赖，但当我部署在aws lambda然后这个依赖没有找到。从'node-fetch'中导入fetch;

Answer 1

必须将外部包声明为lambda的层https://docs.aws.amazon.com/lambda/latest/dg/configuration-layers.html

Answer 2

我使用Node版本18.x有同样的问题，降级到16.x后修复

这可以在lambda页面中完成->向下滚动到Runtime settings

我希望你已经解决了这个问题，但我把这篇文章贴出来，以防有人觉得它有用。
