Angular 6 资产文件夹未在浏览器上呈现

Question

我正在学习 angular，我正在尝试将 assets 文件夹中的本地图像加载到 main.component.html 并且我已正确设置路径，同时我按 alt+单击它打开图像的路径。但是图片没有在浏览器上加载。

我得到的错误

在 chrome 开发人员工具的源选项卡中，没有 assets 文件夹包含

这是我的 angular cli 版本

我试过了https://github.com/angular/angular-cli/issues/5268但是没有用，请有人帮忙这是我的 angular.json 文件

Answer 1

通常你需要在你的 index.html 中添加你的 base href 前缀 :

base href="/game-of-thrones/"

为了在正确的文件夹中查找资产。

Answer 2

我有同样的问题

GET http://localhost:4200/assets/img/img.png 404 (Not Found)

但我通过删除项目路径中的所有特殊字符（'('、'@'、'$' 等）修复了它。例如，如果您有一个像

这样的项目路径

C:\angular-projects(1)\angularapp

然后改成

C:\angularprojects1\angularapp

Answer 3

通过删除应用程序文件夹位置的所有特殊字符、符号找到了解决上述问题的方法，看看这个Github issue。

比如你的项目在E盘，

更改此位置

E:\Data\project - 1\Angular(learning)\app

到

E:\Data\project1\Angularlearning\app

然后您将能够在 chrome 开发人员工具中的源选项卡下看到加载到浏览器的资产文件夹。
