问题

我目前正在使用一些AWS Lambda 函数并在本地对其进行测试。通常，该命令sam build需要很长时间才能完成，所以我搜索了一种优化它的方法并找到了sam build --cached --user-container.

在终端中运行它时，它工作得非常好，创建了以下文件夹结构：

2021-12-22 18:56:07 [INFO]: Preparing to debug locally: Lambda ""

During handling of the above exception, another exception occurred:

缓存结构

但是，当我尝试使用launch.jsonVSCode 进行调试时，它给了我这个错误：

启动.json

{
"configurations": [
    {
        "type": "aws-sam",
        "request": "direct-invoke",
        "name": "Invoke Lambda: FunctionX",
        "justMyCode": false,
        "invokeTarget": {
            "target": "template",
            "templatePath": "template.yaml",
            "logicalId": "FunctionX",
        },
        "sam": {
            "containerBuild": true,
            "buildArguments": [
                "-u",
                "--cached",
            ]
        },
        "lambda": {
            "timeoutSec": 9999
        }
    }
]

}

如您所见，当我尝试调试它时构建失败。

我试图做什么

我的第一次尝试是手动输入缓存目录添加--cache-dir参数：

启动.json

{
"configurations": [
    {
        "type": "aws-sam",
        "request": "direct-invoke",
        "name": "Invoke Lambda: FunctionX",
        "justMyCode": false,
        "invokeTarget": {
            "target": "template",
            "templatePath": "template.yaml",
            "logicalId": "FunctionX",
        },
        "sam": {
            "containerBuild": true,
            "buildArguments": [
                "-u",
                "--cached",
                "--cache-dir",
                "${workspaceFolder}/.aws-sam/cache"
            ]
        },
        "lambda": {
            "timeoutSec": 9999
        }
    }
]

}

但是，同样的错误不断发生。然后，我创建了一个samconfig.toml文件并默认将sam build命令配置为sam build -u --cached. 还是没有效果。

在这种情况下，我查看了 GitHub Issues 和 Stack Overflow 问题，但从来没有人遇到过这种问题。在我看来，没有人试图将缓存配置与launch.json一起使用，仅通过终端运行。

如果这甚至可以做到，有人可以给我一个提示吗？

提前感谢所有阅读并试图帮助我的人！
