我们公司的团队遇到了一个似乎无法找到解决方案的问题，我希望这里有人可以帮助我们。我们在Angular 10 / Ionic 5项目中使用AWS Amplify，但确实收到以下错误：
Uncaught ReferenceError: exports is not defined
at Module../node_modules/@aws-sdk/middleware-serde/build/deserializerMiddleware.js (vendor.js:344144)
at __webpack_require__ (bootstrap:84)

这是来自package.json的摘录。我想知道这个问题是否与webpack有关，或者与Angular / Typescript / Ionic相关。

我们还包含（tsconfig.app.json）：

"enableIvy": false,
"fullTemplateTypeCheck": false
},
我发现有多个来源与AWS Amplify和Ionic / Angular有不同的问题，但似乎与您的问题不同。

尝试：
rm -rf node_modules
rm package-lock.json
npm i
对我们的案例有帮助。

解决了相同的问题（Angular 10），并按照aws-sdk-js GitHub Issue页面here上找到的解决方法进行了解决。
简而言之，您必须执行以下两个步骤：
使用npm i --save-dev @types/node安装节点类型
（我知道这很奇怪，因为我们使用的是前端应用程序，但是AWS开发工具包确实需要输入节点）
在"types": ["node"]文件的"compilerOptions"部分中添加tsconfig.app.json。
就我而言，tsconfig.app.json文件变为：
{
"extends": "./tsconfig.json",
"compilerOptions": {
"outDir": "./out-tsc/app",
"types": [
"node"
]
},
"files": [
"src/main.ts",
"src/polyfills.ts"
],
"include": [
"src/**/*.ts",
"src/**/*.d.ts"
],
"exclude": [
"src/**/*.spec.ts"
]
}
