Javascript 生产建设中存在角度问题，但本地开发中不存在角度问题。错误类型错误：无法读取属性'；呼叫'；未定义的

我一直有一个问题，我的Angular 8应用程序中的一个在本地运行（ng serve）时没有问题，正如预期的那样，但是，当在生产（ng build）上构建和运行时，当在我的应用程序中单击组件并运行代码时，它会给我以下错误

控制台中接收到错误：

使用下面的stackblitz示例禁用缩小后出错：

代码：

ng——版本

任何见解都值得赞赏。谢谢

找到解决方案

看看我创建的stackblitz（根据您的设置，角度为8）：

我必须做的一项更改是，使您的代码能够正常工作：

import createHmac from 'create-hmac';

---

否则（

import*as createHmac from'create hmac'；

）会向我抛出一个错误：

createHmac不是一个函数

尝试添加构造函数？当您尝试（ng build--aot）或（ng build--prod）时，是否会出现任何生成错误？@akhouri我没有在运行这些命令时出现生成错误，但是，当运行相同的代码时，应用程序返回相同的错误。我使用了你的stackblitz在本地nginx服务器上进行捆绑和测试，无论你做了什么更改，都会出现相同的原始错误。我认为这与捆绑销售有关，但我还不确定到底是什么。

1. rm -rf /node_modules/ -> npm update -> npm install
2. require() instead of import()
3. es5 to es2015 in tsconfig.json
4. Updating create-hmac and pbkdf2 packages
5. Downgrading @angular/cli and @angular-devkit/build-angular
6. Build with other flags such as ```ng build --build-optimizer --aot```
7. Node v10.15, v10.16, and v12.16
8. Using a constructor for createHmac
9. Using import createHmac from 'create-hmac'
