提问by Hugh McKee
Hei!
嘿！
I'm having this issue since yesterday, and I'm having trouble for find a solution.
我从昨天开始就有这个问题，我很难找到解决方案。
I'm trying to send somethings to my S3 bucket, but this message appear in my console when i try:
我正在尝试向我的 S3 存储桶发送一些内容，但是当我尝试时，此消息出现在我的控制台中：
{ [CredentialsError: Missing credentials in config]
message: 'Missing credentials in config',
code: 'CredentialsError',
errno: 'Unknown system errno 64',
syscall: 'connect',
time: Thu Oct 09 2014 14:03:56 GMT-0300 (BRT),
originalError:

originalError:
{ code: 'Unknown system errno 64',

And this is my code:
这是我的代码：
var s3 = new AWS.S3();
AWS.config.loadFromPath('./AwsConfig.json');
s3.putObject(params, function(err) {
if(err) {
console.log(err);
}
else {
console.log("Succes");
}
});
The credentials are correct. Does anyone know what can be? I've searching but I not find anywhere the solution.
凭据是正确的。有谁知道可以是什么？我一直在搜索，但找不到任何解决方案。
My credentials(fake):
我的凭据（假）：
{
"accessKeyId": "BLALBLALBLALLBLALB",
"secretAccessKey": "BLABLALBLALBLALBLLALBLALLBLALB",
"region": "sa-east-1",
"apiVersions": {
"s3": "2006-03-01",
"ses": "2010-12-01"
}
}
EDIT:
编辑：
For help, all the code:
如需帮助，所有代码：
var fs = require('fs');
var AWS = require('aws-sdk');
var s3 = new AWS.S3();
AWS.config.loadFromPath('./MYPATH.json'); //this is my path to the aws credentials.
var params = {
Bucket: 'testing-dev-2222',
Key: file,
Body: fs.createReadStream(file)
};
s3.putObject(params, function(err) {
if(err) {
console.log(err);
}
else {
console.log("Success");
}
});
New err:
新错误：

Try hardcoding your params and see if you get the error again :
尝试对您的参数进行硬编码，看看是否再次出现错误：
AWS.config.update({
accessKeyId: "YOURKEY",
secretAccessKey: "YOURSECRET",
"region": "sa-east-1" <- If you want send something to your bucket, you need take off this settings, because the S3 are global.
}); // for simplicity. In prod, use loadConfigFromFile, or env variables
var s3 = new AWS.S3();
var params = {
Bucket: 'makersquest',
Key: 'mykey.txt',
Body: "HelloWorld"
};
s3.putObject(params, function (err, res) {
if (perr) {
console.log("Error uploading data: ", err);
} else {
console.log("Successfully uploaded data to myBucket/myKey");
}
});

I had the same problem until I reversed the two lines:
我遇到了同样的问题，直到我颠倒了两行：
var s3 = new AWS.S3();
AWS.config.loadFromPath('./AwsConfig.json');
to this:
对此：
AWS.config.loadFromPath('./AwsConfig.json');
var s3 = new AWS.S3();

I was having the same error. But I found the issue. I was using wrong Environment variable name. From NodeJS to S3, I need to use the following variable names:
我有同样的错误。但是我发现了这个问题。我使用了错误的环境变量名称。从 NodeJS 到 S3，我需要使用以下变量名：
process.env.AWS_ACCESS_KEY_ID = 'XXXXXXXXXXXXXXXXXXX';
process.env.AWS_SECRET_ACCESS_KEY = 'XXXXXXXXXXXXXXXXXXXXXXXXXX';
process.env.AWS_REGION = 'us-east-1';
Once I corrected the variable names, it just ran fine. regards, Dipankar
一旦我更正了变量名称，它就运行良好。问候， 迪潘卡尔

Try changing the user in my aws config file from a specific user to [default].
尝试将我的 aws 配置文件中的用户从特定用户更改为 [default]。
$nano .aws/credentials
[default]
aws_access_key_id = xyz
aws_secret_access_key = xyz
If you do not have this file, create it and get your keys or generate new one from aws iam user keys.
如果您没有此文件，请创建它并获取您的密钥或从 aws iam 用户密钥生成新的密钥。

I tried above option and even that did not work, so I created new config object and this below code worked
我尝试了上面的选项，即使它也不起作用，所以我创建了新的配置对象，下面的代码有效
AWS.config = new AWS.Config();
AWS.config.accessKeyId = "AccessKey";
AWS.config.secretAccessKey = "SecretAccessKey";

I had a similar issue when trying to load the config file from anywhere other than the root directory.
尝试从根目录以外的任何地方加载配置文件时，我遇到了类似的问题。
I was able to load the json file natively in node, then just pass the object that was parsed to AWS.config.update()
我能够在节点中本地加载 json 文件，然后只需将解析的对象传递给 AWS.config.update()
import AWS from 'aws-sdk'
import config from '../aws.json'
AWS.config.update(config);

Do not hard code credential in the file .
