AWS CDK 说“this”类型的参数不可分配给“Construct”类型的参数

Question

我正在处理一个问题，该问题在 stackoverflow 上发布了一些其他类似的解决方案

(1) “this”类型的参数不可分配给 AWS CDK 中“Construct”类型的参数

(2) AWS CDK，typescript - “this”类型的参数不可分配给“Construct”类型的参数

我尝试按照以下建议使我所有的 aws 库版本匹配：

“这可能是因为您使用的 CDK 模块与 CDK 核心库的版本不同。CDK 更新非常频繁，所以这是一个很常见的错误。

要解决此问题，您需要将所有 cdk 包更新到同一版本。”

这里用不同的词重复了这个建议，所以我做了所有这些：

Delete node_modules folder
Delete package-lock.json
Ensure all dependencies in package.json are using same version.
Remove carrot ^ symbol before dependencies
npm install

现在我的 package json 是这样的：

{
    "name": "cdk-eb-infra",
    "version": "0.1.0",
    "bin": {
        "cdk-eb-infra": "bin/cdk-eb-infra.js"
    },
    "scripts": {
        "build": "tsc",
        "watch": "tsc -w",
        "test": "jest",
        "cdk": "cdk"
    },
    "devDependencies": {
        "@types/jest": "^29.2.4",
        "@types/node": "18.11.15",
        "aws-cdk": "2.59.0",
        "jest": "^29.3.1",
        "ts-jest": "^29.0.3",
        "ts-node": "^10.9.1",
        "typescript": "~4.9.4"
    },
    "dependencies": {
        "@aws-cdk/aws-elasticbeanstalk": "1.187.0", // note identical versions
        "@aws-cdk/aws-iam": "1.187.0", // note identical versions
        "@aws-cdk/aws-s3-assets": "1.187.0", // note identical versions
        "@aws-cdk/core": "1.187.0", // note identical versions
        "aws-cdk-lib": "2.59.0",
        "constructs": "^10.0.0",
        "source-map-support": "^0.5.21"
    }
}

现在我尝试运行cdk deploy我得到

lib/cdk-eb-infra-stack.ts:20:57 - error TS2345: Argument of type 'this' is not assignable to parameter of type 'Construct'.
  Type 'CdkEbInfraStack' is missing the following properties from type 'Construct': onValidate, onPrepare, onSynthesize, validate, and 2 more.

                                                           ~~~~

46         const instanceProfile = new iam.CfnInstanceProfile(this, myProfileName, {

解决办法是什么？

编辑：在/lib文件夹中共享我的cdk-eb-infra-stack.ts文件的（抱歉，长）代码：

import * as cdk from "aws-cdk-lib";
import iam = require("@aws-cdk/aws-iam");
import elasticbeanstalk = require("@aws-cdk/aws-elasticbeanstalk");
import s3assets = require("@aws-cdk/aws-s3-assets");
import { Construct } from "constructs";
// import * as sqs from 'aws-cdk-lib/aws-sqs';

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

        // The code that defines your stack goes here
        // Construct an S3 asset from the ZIP located from directory up.
        const webAppZipArchive = new s3assets.Asset(this, "WebAppZip", {
            path: `${__dirname}/../app.zip`,
        });

        // Create a ElasticBeanStalk app.
        const appName = "MyWebApp";
        const app = new elasticbeanstalk.CfnApplication(this, "Application", {
            applicationName: appName,
        });

        // Create an app version from the S3 asset defined earlier
        const appVersionProps = new elasticbeanstalk.CfnApplicationVersion(this, "AppVersion", {
            applicationName: appName,
            sourceBundle: {
                s3Bucket: webAppZipArchive.s3BucketName,
                s3Key: webAppZipArchive.s3ObjectKey,
            },
        });

        // Make sure that Elastic Beanstalk app exists before creating an app version
        appVersionProps.addDependsOn(app);

        // Create role and instance profile
        const myRole = new iam.Role(this, `${appName}-aws-elasticbeanstalk-ec2-role`, {
            assumedBy: new iam.ServicePrincipal("ec2.amazonaws.com"),
        });

        const managedPolicy = iam.ManagedPolicy.fromAwsManagedPolicyName("AWSElasticBeanstalkWebTier");
        myRole.addManagedPolicy(managedPolicy);

        const myProfileName = `${appName}-InstanceProfile`;

        const instanceProfile = new iam.CfnInstanceProfile(this, myProfileName, {
            instanceProfileName: myProfileName,
            roles: [myRole.roleName],
        });
    }
}

我完全复制粘贴了模块 2：使用 AWS CDK 创建基础设施

Answer 1

看来您正在混合使用 CDKv1 和 CDKv2 包。

CDKv2 迁移文档

这将属于Ensure all dependencies in package.json are using same version.

改变

"dependencies": {
    "@aws-cdk/aws-elasticbeanstalk": "1.187.0", // note identical versions
    "@aws-cdk/aws-iam": "1.187.0", // note identical versions
    "@aws-cdk/aws-s3-assets": "1.187.0", // note identical versions
    "@aws-cdk/core": "1.187.0", // note identical versions
    "aws-cdk-lib": "2.59.0",
    "constructs": "^10.0.0",
    "source-map-support": "^0.5.21"
}

到

"dependencies": {
    "aws-cdk-lib": "2.59.0", // CDKv2
    "constructs": "^10.0.0",
    "source-map-support": "^0.5.21"
}

编辑：根据@fedonev 的回答

像这样更新您的导入：

import {
  aws_iam as iam,
  aws_elasticbeanstalk as elasticbeanstalk,
  aws_s3_assets as s3_assets,
} from "aws-cdk-lib";

在 V2 中，只有不稳定的“alpha”模块在单独的包中。

对不起，我是 StackOverflow 上引用的新手。 编辑是否有更好的方法来归因@fedonev

Answer 2

您正在混合V1 和 V2依赖项。 删除 V1 依赖项，即package.json中版本1.187.0的包。 从aws-cdk-lib导入特定于服务的包：

import {
  aws_iam as iam,
  aws_elasticbeanstalk as elasticbeanstalk,
  aws_s3_assets as s3_assets,
} from "aws-cdk-lib";

在 V2 中，只有不稳定的“alpha”模块在单独的包中。

Answer 3

Fedonev 和 Jacob Greenbow 都发布了有用的回复。 我能够进行以下更改并使其正常工作：

import { Stack, StackProps, aws_iam as iam, aws_elasticbeanstalk as elasticbeanstalk, aws_s3_assets as s3_assets } from "aws-cdk-lib";
import { Construct } from "constructs";
// import * as sqs from 'aws-cdk-lib/aws-sqs';

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

        // The code that defines your stack goes here
        // Construct an S3 asset from the ZIP located from directory up.
        const webAppZipArchive = new s3_assets.Asset(this, "WebAppZip", {
            path: `${__dirname}/../app.zip`,
        });

        // Create a ElasticBeanStalk app.
        const appName = "MyWebApp";
        const app = new elasticbeanstalk.CfnApplication(this, "Application", {
            applicationName: appName,
        });

        // Create an app version from the S3 asset defined earlier
        const appVersionProps = new elasticbeanstalk.CfnApplicationVersion(this, "AppVersion", {
            applicationName: appName,
            sourceBundle: {
                s3Bucket: webAppZipArchive.s3BucketName,
                s3Key: webAppZipArchive.s3ObjectKey,
            },
        });

        // Make sure that Elastic Beanstalk app exists before creating an app version
        appVersionProps.addDependsOn(app);

        // Create role and instance profile
        const myRole = new iam.Role(this, `${appName}-aws-elasticbeanstalk-ec2-role`, {
            assumedBy: new iam.ServicePrincipal("ec2.amazonaws.com"),
        });

        const managedPolicy = iam.ManagedPolicy.fromAwsManagedPolicyName("AWSElasticBeanstalkWebTier");
        myRole.addManagedPolicy(managedPolicy);

        const myProfileName = `${appName}-InstanceProfile`;

        const instanceProfile = new iam.CfnInstanceProfile(this, myProfileName, {
            instanceProfileName: myProfileName,
            roles: [myRole.roleName],
        });
    }
}

请注意， Stack和StackProps也必须导入以避免破坏亚马逊示例的 rest。
