【问题描述】:
我正在尝试使我的 webpack.config 与子文件夹中的图像一起使用。 我遇到了麻烦。 我花了最后一天半的时间在互联网上搜索并阅读了各种解决方案,但无济于事。
我的 src 文件是:
/src/images/data/
/src/容器
我的问题是: 我有一条路线: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
如果我使用以下方法调用图像:
<img src="../images/data/NotFound.png"/> 然后图像显示没有任何问题。
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 开发人员工具检查图像时,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,图像不会加载。
如果我改为导航到 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,图像无法加载。
这就是为什么我认为我的 webpack.config 搞砸了,我需要一些帮助来找出它有什么问题,以便我的图像可以显示。

【问题讨论】:
-
尝试从要求路径中删除
../ -
我已经试过了。带有“images/data/NotFound.png”的路径给出了相同的结果。图像未加载,并且 devtools 显示指向 localhost:7771/games/images/data/NotFound.png 的链接(带有我试图摆脱的额外“游戏”)我什至尝试使用 '/images/data/NotFound.png' 但在这种情况下 webpack 构建失败说它无法解析路径。
-
您是否尝试过设置解析根目录?
-
webpack 2+ 不接受 root。您必须改用模块。我什至尝试将图像/数据文件夹放在那里,但这并没有改变任何东西。这就是我尝试别名的原因。从我的测试中,别名被识别,但结果是一样的
