Question

说明

我在为“ background”属性提及的url（）中收到相对路径错误。

当我使用绝对路径时，似乎工作正常。

错误消息

注意

以前，我有一个单独的文件夹img，但没有在资产文件夹中包含它。当我回答一些问题时，它建议我必须尝试从资产文件夹中加载图像。因此，我将img文件夹复制到资产文件夹，并删除了较旧的img文件夹。但是错误仍然存在

我不明白为什么会这样，有人可以帮我吗。谢谢！

这是文件夹的层次结构

Hierarchy of folders

Answer 1

我想angular可以直接访问Assets文件夹。我们不需要按照层次结构添加“ ../”。

尝试使用-url（assets / img / DSC_0291.JPG）

无需'../'即可直接访问。

Answer 2

好像是Angular 6中的一个已知问题。

举个例子，您最近安装了一个 bootstrap css ，并希望将其添加为全局样式。css然后我们知道这些软件包已添加到“ node_module”中，但如果是角形6我们可以通过在相对路径中使用“ ../”而不是“〜”来引用这些包。

之前

@import“〜/ bootstrap / dist / css / bootstrap.css”;

之后

@import“ ../ node_modules / bootstrap / dist / css / bootstrap.css”;
