Angular2 + Webpack不显示图像 [英] Angular2 + webpack not displaying images

问题描述

我遵循了 Angular2 Webpack教程，但看起来该应用程序无法加载任何图像.这是我的应用程序的目录结构:

I have followed the Angular2 webpack tutorial, but seems like the app cannot load any image. This is the directory structure of my app:

...

/dist/
/src/assets/images/
/src/assets/css/

...

这是文件 config/webpack.common.js 中的Webpack配置:

And this is the webpack configuration on file config/webpack.common.js:

var webpack = require('webpack');
var HtmlWebpackPlugin = require('html-webpack-plugin');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var helpers = require('./helpers');

module.exports = {
  entry: {
    'polyfills': './src/polyfills.ts',
    'vendor': './src/vendor.ts',
    'app': './src/main.ts'
  },

  resolve: {
    extensions: ['.ts', '.js']
  },

  module: {
    rules: [
      {
        test: /\.ts$/,
        loaders: [{
          loader: 'awesome-typescript-loader',
          options: { configFileName: helpers.root('src', 'tsconfig.json') }
        } , 'angular2-template-loader']
      },
      {
        test: /\.html$/,
        loader: 'html-loader'
      },
      {
        test: /\.(png|jpe?g|gif|svg|woff|woff2|ttf|eot|ico)$/,
        loader: 'file-loader?name=assets/[name].[hash].[ext]'
      },
      {
        test: /\.css$/,
        exclude: helpers.root('src', 'app'),
        loader: ExtractTextPlugin.extract({ fallbackLoader: 'style-loader', loader: 'css-loader?sourceMap' })
      },
      {
        test: /\.css$/,
        include: helpers.root('src', 'app'),
        loader: 'raw-loader'
      }
    ]
  },

  plugins: [
    // Workaround for angular/angular#11580
    new webpack.ContextReplacementPlugin(
      // The (\\|\/) piece accounts for path separators in *nix and Windows
      /angular(\\|\/)core(\\|\/)(esm(\\|\/)src|src)(\\|\/)linker/,
      helpers.root('./src'), // location of your src
      {} // a map of your routes
    ),

    new webpack.optimize.CommonsChunkPlugin({
      name: ['app', 'vendor', 'polyfills']
    }),

    new HtmlWebpackPlugin({
      template: 'src/index.html'
    })
  ]
};

现在，如果我尝试向模板中添加一些图像:

Now if I try to add some image to the templates:

<img src="/assets/images/hp-logo.png">

在编译过程中(运行 npm start 时)，我总是遇到以下错误:

I am always getting the following error during compilation (when running npm start):

ERROR in ./src/app/templates/dashboard.component.html
Module not found: Error: Can't resolve './assets/images/hp-logo.png' in '/frontend/src/app/templates'
 @ ./src/app/templates/dashboard.component.html 1:582-620
 @ ./src/app/components/dashboard.component.ts
 @ ./src/app/modules/app.module.ts
 @ ./src/main.ts
 @ multi (webpack)-dev-server/client?http://localhost:3000 ./src/main.ts

我想这与文件加载器有关，但是尝试了不同的配置后，我无法使其正常工作.

I guess it has something to do with the file-loader but after trying different configuration I couldn't get it to work.

有人可以帮我这个忙吗?

Somebody can help me out on this one?

推荐答案

您应该编写相对于模板位置的图像路径.如果您的模板是/src/module1/template.html，则您的图片位置应为

You should write the image path relative to the template location. If your template is e.g. at /src/module1/template.html then your image location should be

<img src="../assets/images/hp-logo.png">
