我试过这些
- 错误 TS2304：找不到名称"缓冲区"，
- https://github.com/aws/aws-sdk-js/issues/994 和
- 将 aws-sdk 与 angular2 结合使用
我的键入和@types/节点似乎已正确安装。以下是错误详细信息：

将"node"添加到 angular-cli 在 src 目录中创建的 tsconfig.app.json 文件中的类型，如下所示：
{
"extends": "../tsconfig.json",
"compilerOptions": {
"outDir": "../out-tsc/app",
"module": "es2015",
"baseUrl": "",
"types": ["node"]
},
"exclude": [
"test.ts",
"**/*.spec.ts"
]
}
基于这些 TypeScript 文档：
指定"类型"：[] 禁用自动包含@types包
由于类型为空，因此它不包括通过 npm install @types/node 安装的节点类型。
In src/tsconfig.app.json
取代
"types": []
与"types": ["node"]
将在 Angular 5 中工作。
我在使用 aws-sdk-js 时遇到了类似的问题。
此问题的原因是节点类型。这就是我所做的
npm install --save @types/node
npm install --save @types/aws-sdk
在 tsconfig.json 中的编译器选项下添加此行
"typeRoots": ["node_modules/@types"],
我找到了解决方案。
您需要安装aws-sdk的类型定义：
npm install --save-dev @types/aws-sdk
在此期间，我从 npm 收到了一些关于无效对等依赖项的错误，但它仍然有效。
但是，在编译应用程序时可能会收到另一个错误，指出aws-sdk中使用的导入语法与 ECMAScript2015 不兼容。我不得不将compilerOptions.module更改为"es5"而不是"es2015"我的tsconfig.app.json才能让它最终工作。
In src/tsconfig-spec.json
