Angular 国际化服务于开发模式

如何解决Angular 国际化服务于开发模式

我想体验 angular i18n (https://angular.io/guide/i18n#build-from-the-command-line)。 我可以用一种语言环境为我的应用程序提供服务，没关系。但是我无法调试应用程序，因为这是捆绑的。

我使用的是 Angular 12

问题 如何在普通开发人员模式下使用国际化 (i18n)（没有捆绑应用程序）？或者也许有一个选项可以在没有 i18n 的情况下进行配置，而使用 i18n 仅在生产模式下构建应用程序？

angular.json

附言 我检查了文档和现场示例 (https://angular.io/generated/live-examples/i18n/stackblitz.html)，但找不到可以帮助我解决这个问题的内容。

解决方法

我找到了解决方案，angular.json 配置中的构建和服务部分存在问题：

这里是差异
