升级到 Angular 11 后，ngx-translate 无法在生产环境中运行

Question

我最近升级到 angular 11，但出于某种原因，我的翻译在生产模式下停止工作。升级后，当我在调试中打开我的应用程序时，我所有的翻译都是空的，但我确实有一些错误。在开发中一切正常，但在生产中我遇到了一些错误：

将你的 ngx-translate 包版本从 v8 升级到支持 angular 10+

的 v13

"@ngx-translate/core": "13.0.0",

检查：https://www.npmjs.com/package/@ngx-translate/core

升级到 Angular 11 后，ngx-translate 无法在生产环境中运行

ngx-translate not working on production after upgrade to Angular 11

angular
