Angular 6 assets文件夹未在浏览器上呈现

Question

我正在学习角度，我正在尝试将assets文件夹中的本地图像加载到main.component.html中并且我已正确设置路径，而我在其打开图像的路径上执行alt +单击。但是图像没有加载到浏览器上。

错误我得到

在chrome developer工具的sources选项卡中，没有包含assets文件夹

这是我的角度cli版本

我试过这个https://github.com/angular/angular-cli/issues/5268但没有用，有人请帮忙这是我的angular.json文件

Answer 1

我也有同样的问题

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

但是我通过删除项目路径中的所有特殊字符（'（'，'@'，'$'等）来修复它。例如，如果你有一个类似的项目路径

C:\angular-projects(1)\angularapp

然后改为

C:\angularprojects1\angularapp

Answer 2

通常，您需要在index.html中为您的基本href添加前缀，如下所示：

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

为了在正确的文件夹中查找资产。

Answer 3

通过删除所有特殊字符，符号到应用程序的文件夹位置，找到解决上述问题的方法，看看这个Github issue。

例如，如果您的项目是在E盘中，

改变这个位置

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

至

E:\Data\project1\Angularlearning\app

然后，您将能够在chrome developer tools的sources选项卡下看到已加载的assets文件夹到浏览器。
