在 Webpack 3 中找不到静态资产

Question

我习惯了 Gulp 并且我在 Webpack 和 Vue.js 中是全新的并且我迷失在所有必要的配置下

我无法在我的应用中使用字体图像等资产。我是在 .vue 组件中还是在我的 .scss 文件中调用它们。

这是我的项目结构：

这是我的 webpack.renderer.config.js:

let rendererConfig = {
  devtool: '#cheap-module-eval-source-map',
  entry: {
    renderer: path.join(__dirname, '../src/renderer/main.js')
  },
  externals: [
    ...Object.keys(dependencies || {}).filter(d => !whiteListedModules.includes(d))
  ],
  module: {
    rules: [
      {
        test: /\.(js|vue)$/,
        enforce: 'pre',
        exclude: /node_modules/,
        use: {
          loader: 'eslint-loader',
          options: {
            formatter: require('eslint-friendly-formatter')
          }
        }
      },
      {
        test: /\.css$/,
        use: ExtractTextPlugin.extract({
          fallback: 'style-loader',
          use: [
            {
              loader: 'css-loader',
              options: {
                sourceMap: true
              }
            } 
          ]
        })
      },
      {
        test: /\.scss$/,
        use: ExtractTextPlugin.extract({
          fallback: 'style-loader',

                sourceMap: true
              }
            }
          ]
        }) 
      },
      {
        test: /\.html$/,

我如何在 .scss 文件中加载图像和字体：

图片：

#wrapper {
  background-image: url('~@/assets/img/photo.jpeg');
  font-family: var(--RobotoRegular);
}

字体：

@font-face {
  font-family: "RobotoRegular";
  src: url("~@/assets/fonts/Roboto-Regular.woff2") format("woff2"),  
         url("~@/assets/fonts/Roboto-Regular.woff") format("woff"),
         url("~@/assets/fonts/Roboto-Regular.otf") format("opentype");  
}

我如何在 vue 组件中加载图像：

<img id="img" src="~@/assets/img/photo.jpeg" alt="img-test">

Webpack 似乎没问题：

但是服务器找不到文件，我不知道为什么

好吧，我所要做的就是在输出中指定一个 publicPath。

output: {
    publicPath: '/',
    filename: 'assets/scripts/[name].js',
    libraryTarget: 'commonjs2',
    path: path.join(__dirname, '../dist/electron')
},

Whosebug 上的这个问题帮助我理解了：What does "publicPath" in Webpack do?
