vue-cli3 public folder img doesn't show up

问题

Does anyone know how to use the src attribute with an img file in a vue project's public folder? The browser is not finding the image.

I'm using Vue CLI 3.7.0

▼ folders

 |
 +-- src
 |    
 +-- public
       |  
       +-- favicon.ico
       +-- logo.png
       +-- index.html

I've tried something like :src="xxx", but that didn't work.

<template>
    <div>
        <img :src="'/favicon.ico'">
        <img :src="`${publicPath}favicon.ico`">
     </div>
</template>

<script>
    export default {
        data: function() {
            return {
                publicPath: process.env.BASE_URL
            };
        }
    }
</script>

Update

From the comments below, it seems you're running

vue serve

Only a Vue CLI project knows about the public directory and process.env.BASE_URL. You need to run your project instead of using the instant prototyping of vue serve.

In other words, run

npm run serve

See https://cli.vuejs.org/guide/cli-service.html#using-the-binary

If you have a file structure like this

├── public
│   ├── favicon.html
│   ├── index.html
│   ├── logo.png

then your code to display logo.png should look like

<template>
  <div>
    <img :src="`${publicPath}logo.png`">
  </div>
</template>

<script>
export default {
  data () {
    return {
      publicPath: process.env.BASE_URL
    }
  }
}
</script>

See https://cli.vuejs.org/guide/html-and-static-assets.html#the-public-folder

If you have your image in

├── public
│   ├── img
│   │   ├── logo.png

then your component template code becomes

<img :src="`${publicPath}img/logo.png`">

Just use <img src="/favicon.ico">.
