The problem of setting picture path by vue

I initialized a project with vuecli, and then there was a problem when I introduced the image. This is what I wrote about the image obtained by js

    {
          src: require("../assets/slideShow/pic1.jpg"),
          title: "xxx1",
          href: "detail/analysis"
        },
This is what I wrote about the pictures on the

page

.index-board-hill .index-board-item-inner{
  background: url(../assets/images/4.png) no-repeat;
}

but all of them are wrong and the path is right.
but reported this error
