angular - 发生未处理的异常：开发服务器仅支持每次构建本地化单个语言环境

问题描述

请告知如何修复此错误，我正在尝试实施本地化但遇到此问题。我使用的指南：https ://angular.io/guide/i18n#merge-translations-into-the-app 如果有帮助，我可以使用 ng serve --configuration=ru --open 运行，并且应用程序已本地化，但是在我使用 _build.bat 之后，它破坏了我的应用程序，我根本无法再运行它。如果我指定不同的端口，则会引发错误“NGCC failed”。这是 angular.json 文件中我的代码示例：
