{
test: /\.(png|jpg|gif)$/,
loader: 'file-loader?name=img/img-[hash:6].[ext]',

我已将此配置添加到webpack.config.js
以通过将上述规则添加到
file-loader
module: {
rules: [
部分,但即使我将图像文件放入dist/
,也没有任何图像文件已移至src/images/
文件夹。有没有我错过的东西需要添加到webpack配置?
我正在关注https://julienrenaux.fr/2015/03/30/introduction-to-webpack-with-practical-examples/
中的示例顺便说一下,我正在使用webpack 2 ...现在有不同的方法来配置文件加载器吗?
这是整个webpack配置文件
const { resolve } = require('path');
const webpack = require('webpack');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const CopyWebpackPlugin = require('copy-webpack-plugin');
const OpenBrowserPlugin = require('open-browser-webpack-plugin');
const config = {
devtool: 'cheap-module-eval-source-map',
entry: [
'react-hot-loader/patch',
'webpack-dev-server/client?http://localhost:8080',
'webpack/hot/only-dev-server',
'./main.js',
'./assets/scss/main.scss',
],
output: {

它在示例中说明了您:
您现在可以使用
来要求任何图像文件require('./src/image_big.jpg')
;
如果你不在某处导入图片,webpack就不会复制它们,因为它只会将file-loader
应用于它看到的导入并符合你的规则。您也可以使用url
在Sass中导入它们,例如:
background-image: url('./src/image.jpg');
.png
和.jpg
还有两条规则:
{ test: /\.(png|jpg)$/, use: 'url-loader?limit=15000' },
{
test: /\.(png|jpg|gif)$/,
loader: 'file-loader?name=img/img-[hash:6].[ext]',
},
选择其中一个。因为现在它将同时应用两者,但实际上只使用其中一个,所以当图像大于15kb时,最终会得到两个图像,因为当文件较大时url-loader
会回落到file-loader
超过配置的限制。

使用以下代码段要求src/images/
内main.js
下的所有文件(或图片所在的位置):
// load assets
function requireAll(r) { r.keys().forEach(r); }
requireAll(require.context('src/images/', true));
这将使Webpack处理该文件夹中的所有文件。

参考:https://angular.io/docs/ts/latest/guide/webpack.html
我建议您尝试上面引用的指南。请注意,您需要运行以下命令才能使其全部正常工作:
npm install --save-dev karma-jasmine-html-reporter
关于您的问题,上面示例指南中的图像是通过html文件通过<img>
标记引用的。这个<img>
引用由webpack获取,图像文件放在已在输出&#34; dist /&#34;中创建的资产目录中。文件夹:
&#34; app.component.html&#34;:
<main>
<h1>Hello from Angular App with Webpack</h1>
<img src="../assets/images/angular.png">
</main>
