无法使用 CDK + Lambda 捆绑资产错误

我有这个项目结构（其中control是我的项目的名称和根）：

control
|_ src
  |_ control_loader -> this has a function inside called also control_loader
  |_ utils
     |_ some_helper_function.py
     |_ __init__.py
  |_ __init__.py
|_ lib
   |_ some-cdk-where-i-declare-a-lambda.ts
|_ requirements.txt

Inside some-cdk-where-i-declare-a-lambda.ts我有这个（以及所有其他必要的东西）：

        new Function(this, `${this.appName}${this.stageName}ControlLambdaLoader`, {
            code: Code.fromAsset(path.join(__dirname, '../src'), {
                bundling: {
                    image: Runtime.PYTHON_3_8.bundlingImage,
                    command: [
                        'bash', '-c',
                        'pip install -r requirements.txt -t /asset-output && cp -au . /asset-output',
                    ],
                },
            }),
            runtime: Runtime.PYTHON_3_8,
            handler: 'control_loader.control_loader',
            vpc,
            vpcSubnets: vpc.selectSubnets({
                subnetType: SubnetType.PRIVATE_WITH_NAT,
            }),
        });

然而，在运行时cdk synth，我得到以下信息：

(venv) PS C:\Users\rodri\Documents\control> cdk synth
npx: installed 15 in 1.145s
Bundling asset controlPipelineStack/controlBetaDeployStage/controlbetaStack/controlbeta/controlbetaControlLambdaLoader/Code/Stage...
Failed to bundle asset controlPipelineStack/controlBetaDeployStage/controlbetaStack/controlbeta/controlbetaControlLambdaLoader/Code/Stage, bundle output is located at C:\Users\rodri\Documents\control\cdk.out\asset.059c3b383943a1fadd3d933b670a7d351991e742d24a9785474b35c846267fde-error: Error: spawnSync docker EN
OENT

这是一个非常神秘的错误。我知道捆绑是由 docker 完成的，以将依赖项作为 zip 资产推送，但是，知道这个失败在哪里吗？我也尝试过改变位置requirements.txt到里面src但这没有帮助。我可以部署删除 Lambda 后的所有内容。我究竟做错了什么？另外，如何使捆绑包含some_helper_function.py还有？

Thanks!

您可能需要在本地捆绑 Python 函数：

import * as cdk from '@aws-cdk/core';
import { Code, Runtime, Function} from '@aws-cdk/aws-lambda';
import * as path from 'path';
import { execSync } from 'child_process';

export class CdkLocalBundlingExampleStack extends cdk.Stack {
  constructor(scope: cdk.Construct, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    const functionDir = path.join(__dirname, "functions", "exampleFunction")

    const exampleFunction = new Function(this, "ExampleFunction", {
      handler: 'index.handler',
      runtime: Runtime.PYTHON_3_8,
      code: Code.fromAsset(functionDir, {
        bundling: {
          image: Runtime.PYTHON_3_8.bundlingImage,
          local: {
            tryBundle(outputDir: string) {
              try {
                execSync('pip3 --version')
              } catch {
                return false
              }

              execSync(`pip install -r ${path.join(functionDir, "requirements.txt")} -t ${path.join(outputDir)}`)
              execSync(`cp -au ${functionDir}/* ${path.join(outputDir)}`)
              return true
            }
          }
        }
      })
    })
  }
}
