在 Mac 上为 lambda 容器安装 Delve 无法完成

本篇文章向大家介绍《在 Mac 上为 lambda 容器安装 Delve 无法完成》，主要包括，具有一定的参考价值，需要的朋友可以参考一下。

我使用 vs code aws 工具包和 sam 创建了一个基于 go 的基本 sam web 应用程序（我是 vs code 生成的）。

这是 lambda 的一些通用模板代码，它从请求中读取 ip 并在浏览器上返回 hello 。

我的最终目标是设法在 vs code 中查看 lambda 函数的逐行调试。

我的launch.json中似乎有一些默认配置：

{
    "configurations": [
        {
            "type": "aws-sam",
            "request": "direct-invoke",
            "name": "sunflowers:helloworldfunction (go1.x)",
            "invoketarget": {
                "target": "template",
                "templatepath": "${workspacefolder}/sunflowers/template.yaml",
                "logicalid": "helloworldfunction"
            },
            "lambda": {
                "payload": {},
                "environmentvariables": {},
                "runtime": "go1.x"
            }
        },
        {
            "type": "aws-sam",
            "request": "direct-invoke",
            "name": "api sunflowers:helloworldfunction (go1.x)",
            "invoketarget": {
                "target": "api",
                "templatepath": "${workspacefolder}/sunflowers/template.yaml",
                "logicalid": "helloworldfunction"
            },
            "api": {
                "path": "/hello",
                "httpmethod": "get",
                "payload": {
                    "json": {}
                }
            },
            "lambda": {
                "runtime": "go1.x"
            }
        }
    ]
}

但是，单击“开始调试”按钮时，我收到无法安装 delve 的错误：

我的 lambda 需要架构 amd64，而我的 mac 具有 m1 芯片，因此它的架构为 arm64。上述错误是由于架构不匹配造成的吗？

我尝试使用 docker 在本地运行 lambda 并且有效（使用 sam local start-api 和 sam local invoke），但我不确定使用调试器时上述工作是否顺利。

正确答案

事实证明，这是由于 VS Code 的 AWS Toolkit 扩展中的错误造成的。该问题已在 AWS Toolkit 1.47 中修复。
