将 Angular 从 v.11 升级到 v.12 后，我收到以下错误

home.Component.ts

imgname= require("../assets/images/imgname.png");

./src/assets/images/imgname.png:1:0- 错误：模块解析失败：意外字符 '�' (1:0) 您可能需要适当的加载程序来处理此文件类型，目前没有配置加载程序来处理此文件。请参阅https://webpack.js.org/concepts#loaders （此二进制文件省略了源代码）

不幸的是，我无法回答，但可能有更多信息。尽管在升级到 Angular v12 时，我似乎遇到了类似的问题。我相信在我的情况下，它与在我的 Angular.json 中执行以下内容有关。在我的情况下，这些行正在尝试复制资产以在 Angular 内使用 Leaflet，并且它不再能够复制 .png 资产。

...
            "assets": [

              {
                "glob": "**/*",
                "input": "./node_modules/leaflet/dist/images",
                "output": "/assets/leaflet/"
              }

            ],
...

谢谢
