angular应用程序在prod上抛出错误，但在dev上工作正常

// environment.ts
export const environment = {
  production: false,
  apiUrl: 'http://dev.api.example.com'
};

// environment.prod.ts
export const environment = {
  production: true,
  apiUrl: 'http://prod.api.example.com'
};

ng build --prod

{
  "dependencies": {
    "@angular/core": "^12.0.0",
    // 其他依赖
  }
}

ng build --prod --aot --build-optimizer
