如何在Angular应用中设置国际化配置

Question

我一直在尝试向我的角度应用程序添加国际化，但是当我尝试使用以下命令运行该应用程序时：ng serve --configuration=es

我收到此错误消息：

  

在项目中找不到配置'es'

我一直在关注this教程，并将production-es部分添加到下面的 angular.json 文件中：

          }
        }
      }
    }
  },
  "defaultProject": "internationalApp"
}

有人可以告诉我为什么不选择此国际化配置吗？需要进行哪些更改才能使我的应用选择此配置？

这也是我的“语言环境”文件夹所在的位置：

您缺少es的es配置

"serve": {
      "builder": "@angular-devkit/build-angular:dev-server",
      "options": {
        "browserTarget": "internationalApp:build"
      },
      "configurations": {
        "production": {
          "browserTarget": "internationalApp:build:production"
        },
        "es": { // add this
          "browserTarget": "internationalApp:build:production-es"
        },
      }
    },

您现在可以运行 ng serve --configuration = es
