Question

我正在尝试让我的webpack.config与子文件夹中的图像一起使用。而且我遇到了麻烦。我花了最后一天半在网上搜索并阅读各种解决方案无济于事。

我的src文件是：

/ SRC /图像/数据/

/ SRC /容器

我的问题是：我有一个路由：http://localhost:7771/games/O从/ src / containers加载在该页面上，我正在尝试加载/src/images/data/NotFound.png

如果我使用以下方式调用图像： <img src="../images/data/NotFound.png"/>然后图片显示没有任何问题。

但是，如果我将路径更改为<img src={require("../images/data/NotFound.png")}/>，则图像不会显示。当我使用Chrome开发者工具检查图像时，我看到该元素显示为： <img src="images/data/NotFound.png"> 如果我将鼠标悬停在src链接上，我会看到：http://localhost:7771/games/images/data/NotFound.png 但是如果我尝试打开该链接，图像就不会加载。

如果我导航到http://localhost:7771/images/data/NotFound.png，则会加载图像。

我尝试使用别名进行解析并将图像更改为<img src={require("~/data/NotFound.png")}>，但结果相同，图片无法加载。

这就是为什么我认为我的webpack.config搞砸了，我想帮助找出它的错误，以便我的图像可以显示。

output.path尊重Woocommerce，因为您没有设置它，它使用相对于/的路径，并且在使用其他路线时无效。要解决此问题，只需将公共路径设置为output: { path: path.join(__dirname, "src"), filename: 'bundle-hot.js', publicPath: '/' },：

file-loader

如果您不想设置publicPath，

output.publicPath也有一个选项<img src="/images/data/NotFound.png">，因为它也会影响其他加载器，但这通常是您想要的，因此建议。有了这个，你会得到：

images

您也无需复制file-loader目录，因为CopyWebpackPlugin会复制您导入的图片。实际上，它使用URL来复制文件。所以你应该从#!/bin/bash read -p "Enter first number: " num1 read -p "Enter second number: " num2中删除它，除非你的图像没有被webpack处理。
