用于多个i18n语言环境的angular.json设置

问题描述

我将我的项目设置为两个语言环境构建，每个语言环境都位于各自的URL（通过configuration.<locale>.baseRef）。尽管此设置使我的开发服务器无法使用，但它可以很好地用于构建项目（通过ng build）。如果我尝试运行npm start，则会出现以下错误：

An unhandled exception occurred: The development server only supports localizing a single locale per build

这使得我不得不从projects.<app-name>.architect.build.options.localize选项中删除一个构建名称（开发服务器将从["en-US"]处的设置开始，而不是["en-US","es-ES"]）

我知道它很冗长，但是我在下面包含了angular.json的全部内容。我不知道需要调整哪些部分以允许构建多个可分发目录，同时仍然允许使用简单的开发服务器
