我已经检查了我的文件很多次，我想我已经在我的 lambda_function.py 中创建了 lambda_handler。还是没成功。

回应： { "errorMessage": "模块'lambda_function'上缺少处理程序'lambda_handler'", "errorType": "Runtime.HandlerNotFound", “请求ID”：“”， “堆栈跟踪”：[] }
我已经上传了这个结构的文件
lambda_function.py
boto3/
psycopg2/
requests/
但在AWS
lambda_function/lambda_function.py
boto3/
psycopg2/
requests/
所以我将 lambda_function.py 移出尝试 并测试功能 它给了我一个错误 回复： { "errorMessage": "模块'lambda_function'上缺少处理程序'lambda_handler'", "errorType": "Runtime.HandlerNotFound", “请求ID”：“”， “堆栈跟踪”：[] }
尝试直接使用 CLI 压缩文件：
zip -r deployment_package.zip lambda_function.py boto3/ psycopg2/ requests/
这将确保您的 lambda_function 位于根目录中。 对于 lambda_handler，尝试从 aws 控制台定义：
def lambda_handler(event, context):
pass
看看你是否会继续遇到同样的错误。
