AWS CDK -无法增加Lambda超时

Question

    const postReader_NewPost = new lambda.Function(this, 'PostReader_NewPost', {
      code: lambda.Code.fromAsset('lambda'),
      runtime: lambda.Runtime.PYTHON_2_7,
      handler: 'PostReader_NewPost.handler',
      timeout: Duration.seconds(300),
      description: "",
      environment: {
        "DB_TABLE_NAME": table.tableName,
        "SNS_TOPIC": topic.topicArn
      },
      role:role,
    });

我得到以下错误

Type 'import("c:/Users/myusername/Documents/GitHub/cdk_polly_website/node_modules/@aws-cdk/core/lib/duration").Duration' is not assignable to type 'import("c:/Users/myusername/Documents/GitHub/cdk_polly_website/node_modules/@aws-cdk/aws-dynamodb/node_modules/@aws-cdk/core/lib/duration").Duration'.
  Types have separate declarations of a private property 'amount'.ts(2322)
function.d.ts(68, 14): The expected type comes from property 'timeout' which is declared here on type 'FunctionProps'

我声明我在班上名列前茅

import { Duration } from '@aws-cdk/core';

我的package.json有以下依赖项

"dependencies": {
    "@aws-cdk/aws-apigateway": "^1.88.0",
    "@aws-cdk/aws-dynamodb": "^1.88.0",
    "@aws-cdk/aws-iam": "^1.88.0",
    "@aws-cdk/aws-lambda": "^1.88.0",
    "@aws-cdk/aws-lambda-event-sources": "^1.88.0",
    "@aws-cdk/aws-sns": "^1.88.0",
    "@aws-cdk/aws-sns-subscriptions": "^1.88.0",
    "@aws-cdk/core": "1.88.0",
    "source-map-support": "^0.5.16"
  }

感谢你的帮助。谢谢

Answer 1

这种方式对我来说总是有效的：aws-examples

导入核心，然后使用Duration作为core.Duration。

我不确定它是否会有帮助，但看起来您的核心导入是以这种方式从aws-dynamodb获取的。

如果这解决了问题，我想调查一下原因。

通过npm ls，我发现我没有相同版本的不同aws cdk库

npm ls
cdk_polly_website@0.1.0 C:\Users\amuham210\Documents\GitHub\cdk_polly_website
+-- @aws-cdk/assert@1.88.0
+-- @aws-cdk/aws-apigateway@1.89.0
+-- @aws-cdk/aws-dynamodb@1.89.0
+-- @aws-cdk/aws-iam@1.89.0
+-- @aws-cdk/aws-lambda-event-sources@1.89.0
+-- @aws-cdk/aws-lambda@1.89.0
+-- @aws-cdk/aws-sns-subscriptions@1.89.0
+-- @aws-cdk/aws-sns@1.89.0
+-- @aws-cdk/core@1.88.0
+-- @types/jest@26.0.20
+-- @types/node@10.17.27
+-- aws-cdk@1.88.0
+-- jest@26.6.3
+-- source-map-support@0.5.19
+-- ts-jest@26.5.1
+-- ts-node@9.1.1
`-- typescript@3.9.9

所以我显式地安装了版本以使其相同

npm install @aws-cdk/core@1.89.0

这就解决了这个问题。

您使用的是@ aws-cdk / core和@ aws-cdk / aws-lambda的不同版本。
