node.js – 创建AWS SQS队列

我正在尝试使用node.js从EC2实例在AWS上创建SQS队列.
在同一个实例中,我可以使用node.js访问S3并列出存储桶等.该实例具有IAM角色,可授予对S3和SQS的完全访问权限.

然而,执行以下代码失败了,我无法弄清楚原因.更有趣的是,从我的电脑中,代码实际上是有效的.

var AWS = require('aws-sdk');
AWS.config.update({region:'eu-central-1'});
//console.log("awsv "+AWS.VERSION); --> 2.3.5
var sqs = new AWS.SQS();
 var params = {
  QueueName: "MyQueue1"
 };
 sqs.createQueue(params, function(err, data) {
   if (err) console.log(err, err.stack); // an error occurred
   else {
        if(data)
                console.log(data);           // successful response
        else
                console.log("Other unknown error");
   }
 });

错误信息：

/home/ubuntu/aws-nodejs-sample/node_modules/aws-sdk/lib/http/node.js:121
      callback();
      ^
TypeError: undefined is not a function
    at Writable.writer._write (/home/ubuntu/aws-nodejs-sample/node_modules/aws-sdk/lib/http/node.js:121:7)

    at process._makeCallback (node.js:345:15)

事实证明,使用调用CLI函数的脚本进行快速测试实际上是有效的：

var AWS = require('aws-sdk');
AWS.config.region = 'eu-central-1';

var qUrl="https://sqs.eu-central-1.amazonaws.com/......./awsquerytest";

var queue = new AWS.SQS({params: {QueueUrl: qUrl}}); // using url to queue
var receipthandle;
var fs = require('fs');

var child = require('child_process').exec('aws sqs receive-message --queue-url https://sqs.eu-central-1.amazonaws.com/....../awsquerytest');
child.stdout.on('data', function(data) {
   var x= data.toString();
   console.log(data.toString());
   fs.writeFile("/home/ubuntu/aws-nodejs-sample/output",x,function(err){
if(err){
return console.log(err);
}
console.log("oldu");
});
});

child.stderr.on("data", function (data) {
    console.log(data.toString());
});

怎么解释这个？

看起来这与您在Ubuntu服务器上安装的不同版本的节点与本地计算机有关.

你在本地和服务器上运行什么节点–version？
