出现未处理的异常：工作区中未设置配置“es5”。

问题始于客户希望在Internet Explorer 8上运行该项目。幸运的是，新的Angular 8提供了差异加载功能。

根据Angular文档(https://angular.io/guide/deployment#differential-loading)所述，我在angular.json中添加了es5 JSON，然后尝试使用“ng serve --configuration es5”进行服务。

错误是

未处理的异常：工作区中未设置配置“es5”。 请参阅“/tmp/ng-iPbP2O/angular-errors.log”获取更多详细信息。

我该如何使其工作？

你直接在生产环境中提供服务吗？ - skolldev
不是为生产服务，而是为es5服务。我使用'ng serve --configuration es5'进行服务... 为生产服务则使用'ng build --watch'。 - abrsh
你尝试检查一下"/tmp/ng-iPbP2O/angular-errors.log"文件，看看它是否有关于这个问题的任何信息可以提供任何想法了吗？如果可能的话，也请尝试分享该日志文件的内容。 - Deepak-MSFT
是的，我检查过了。这是相同的错误，但如果有帮助的话...这是它的内容：[error] 错误：工作区中未设置配置“es5”。 at WorkspaceNodeModulesArchitectHost.getOptionsForTarget (/home/abrsh/Documents/forex/node_modules/@angular-devkit/architect/node/node-modules-architect-host.js:72:19) at ArchitectTargetJobRegistry.get - abrsh

您似乎把ES5配置放在了“serve”部分，而不是“configurations”部分。

另外，您需要将"app:build:es5"更改为您的应用程序名称。因此，在您的情况下是"sm:build:es5"。

"serve": {
    "builder": "@angular-devkit/build-angular:dev-server",
    "options": {
      "browserTarget": "sm:build"
    },
    "configurations": {
      "production": {
        "browserTarget": "sm:build:production"
      },
      "es5": {
        "browserTarget": "sm:build:es5"
      }
    }
  }

它对我起作用了。谢谢。 - Analyst
