Lambda Docker 映像未运行

Question

我在尝试安装 Snowflake python 连接器时经历了一段非常糟糕的时光。这是一个令人沮丧的事情，但我终于成功地使用完整的 Ubuntu 基础 Docker 镜像来安装它。但我现在不知道如何让 AWS lambda 包装器工作。

使用此入口文件：

#!/bin/sh
if [ -z "${AWS_LAMBDA_RUNTIME_API}" ]; then
    exec /usr/bin/aws-lambda-rie python3 -m awslambdaric $1
else
    exec python3 -m awslambdaric $1
fi

注意：我删除了 python3 的路径
