Webpack：无法使用文件加载器显示 SVG 图像（svg 解析错误）

Question

我使用 require 使用的 SVG 没有显示出来。

在我的终端中，发出了 svg 资源，并且在我的 html 中正确设置了路径。

<img src="/images/brand-illustration.f20767e375d3094978f5cc5c9726d0a6.svg">

但是，当 jpg 或 png 等其他格式有效时，SVG 不会显示。我尝试打开原始 svg 文件，它确实有效。 当我检查发出的 svg 资产并将其加载到浏览器中时，如下所示：localhost:8080/images/brand-illustration.f20767e375d3094978f5cc5c9726d0a6.svg，我得到了这个parse error：

这就是我在 pug 文件中使用 svg 的方式

img(src=require('../../assets/img/brand-illustration.svg').default)
