错误:找不到模块'@aws-sdk/client-sns‘
当我调用我的lambda时，我得到了这个错误。
"errorType"："Runtime.ImportModuleError"，"errorMessage"：“错误:找不到模块‘@aws-sdk/client-sns’\n请求堆栈：\n- /var/task/handler.js\n- /var/runtime/UserFunction.js\n- /var/runtime/index.js"，”errorMessage“：[ "Runtime.ImportModuleError:错误:找不到模块'@aws-sdk/client-sns'"，
import * as AWS from '@aws-sdk/client-sns';
import { JamaSnsMessage } from './models/jama';
import { region, snsTopicArn } from './utils/constants';
import { log } from './utils/logger';
const client = new AWS.SNS({ region });
/**
* Publishes given SNS formatted Jama items to SNS topic
*
* @param {JamaSnsMessage[]} items
*/
export const publishItems = async (items: JamaSnsMessage[]): Promise<void> => {
if (!items || items.length <= 0) {
return;
}
for (const item of items) {
const params = {
/* eslint-disable */
MessageStructure: 'json',
Message: JSON.stringify(item),
TopicArn: snsTopicArn,
/* eslint-enable */
};
log.info(`Sending jama item: ${JSON.stringify(item)} to sns`);
await send(params);
}
};
export const send = async (params: AWS.PublishInput): Promise<void> => {
try {
const data = await client.send(new AWS.PublishCommand(params));
log.info(`Item: ${JSON.stringify(params)} was published with id: ${data.MessageId}`);
} catch (error) {
log.error(`Error while publishing message ${JSON.stringify(params)}. Cause: ${error}`);
}
};

如果您使用的是SDK的V2，请使用：
var AWS = require('aws-sdk');
AWS.config.update({region: 'REGION'});
// Create promise and SNS service object
const SNS = new AWS.SNS({apiVersion: '2010-03-31'})如果出于大小原因，您只想在Lambda函数中使用SNS模块，我建议您使用AWS SKD for JavaScript的V3。默认情况下，Lambda仍然只与SDK的V2兼容，但有一个变通方法。这是一个example of creating a function using only modules of the AWS SDK for JavaScrpt - version 3。

当我尝试导入AWS SDK for JavaScript v3中记录的DynamoDB V3客户端时，我的Node14 Lambda函数也遇到了类似的问题。
记录的函数：
客户端错误:找不到模块‘@aws-sdk/
- DynamoDB“DynamoDB
我跟随this guide创建了一个Lambda层，并将其附加到Lambda函数。
然而，我认为这个过程是可以简化的--你可以通过CloudShell来完成，而不是启动EC2实例。托管Lambda的区域不需要支持CloudShell。只需从任何支持它的区域启动CloudShell，然后执行以下操作：
# Create the directory
$ mkdir -p aws-sdk-layer/nodejs
$ cd aws-sdk-layer/nodejs
# Add the clients you want to use from the new SDK
$ yarn add @aws-sdk/client-dynamodb @aws-sdk/client-apigatewaymanagementapi
# Create the zip file
$ zip -r ../package.zip ../
# Publish the layer
# In the below, change:
# The layer name (currently node_sdk)
# The description (currently "My layer")
# The region
#
# Copy from the response the value of the "LayerVersionArn" key
#
$ aws lambda publish-layer-version --layer-name node_sdk --description "My layer" --license-info "MIT" --compatible-runtimes nodejs14.x --zip-file fileb://../package.zip --region <specify a region>
# Add the layer to your function
# In the below, change:
# The function name (currently my-function)
# Set the layer's ARN to the value of the "LayerVersionArn" key in the response from the previous statement (currently arn:aws:lambda:us-east-2:123456789012:layer:node_sdk:1)
# The region
#
$ aws lambda update-function-configuration --function-name my-function --layers arn:aws:lambda:us-east-2:123456789012:layer:node_sdk:1 --region <specify a region>你应该可以走了！

该问题与V3 sdk的节点版本10.X有关。当我将节点版本更新到12.X时，它开始工作了。我使用的是AWS CDK，因此我还需要将CDK依赖项更新到1.88.0以获得此12.X支持。
在CDK项目中更改lambda的运行时-
运行时： lambda.Runtime.NODEJS_12_X
