错误[CredentialsError]：配置中缺少凭证，如果使用AWS_CONFIG_FILE，请设置AWS_SDK_LOAD_CONFIG = 1

Question

我已使用aws sns进行消息服务。我已经使用dot env来存储aws-sdk的凭据。应用程序在本地主机上运行良好，但是当我将节点应用程序部署到AWS EC2时，会发生以下错误：错误[CredentialsError]：配置中缺少凭据，如果使用AWS_CONFIG_FILE，请设置AWS_SDK_LOAD_CONFIG = 1 app.js

const dotenv = require("dotenv");
dotenv.config();
const AWS = require("aws-sdk");
AWS.config.update({
  accessKeyId: process.env.ID,
  secretAccessKey: process.env.KEY,
  region: process.env.REGION,
});

Answer 1

使用以下命令在EC2中安装CLI：

curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
unzip awscliv2.zip

unzip awscliv2.zip

sudo ./aws/install

sudo ./aws/install -i /usr/local/aws-cli -b /usr/local/bin

然后在启动服务器导出密钥之前，在项目文件夹中：

export AWS_ACCESS_KEY_ID=AKIAIOSFODNN7EXAMPLE
export AWS_SECRET_ACCESS_KEY=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
export AWS_DEFAULT_REGION=us-west-2
