我正在尝试在angular上实现一个firebase通知。然而，当我在src/中添加manifest.json并在index.html中将其引用为<link rel="manifest" href="./manifest.json">时但是浏览器给了我两个错误404没有找到清单：行：1，列：1，语法错误当我用dom检查它并通过一个新的选项卡打开它时，它被重定向到我的索引，而没有加载资源。我尝试了一些解决方案，但似乎都不起作用。只有当我评论索引上的那一行时，这个错误似乎才会消失。我目前使用的是角度版本7.1.0

似乎错过了将其添加到angular.json文件中。
确保angular.json结构包含manifest.json文件。

-
将src/manifest.json添加到angular.json中的资产数组中
"assets": ["src/assets", "src/favicon.ico", "src/manifest.json"], -
重新启动服务器
