HTML加载程序+文件加载程序未捆绑正确的图像源

我计划将Webpack用于一个项目,并使用Html-loader + file-loader设置工作流程,以获取带有动态src图片的html文件,如Colt Steele在{{3 }}。这是我的src /文件:

index.html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Popular on Letterboxd</title>
</head>
<body>
  <img src="./assets/chira.jpg" />
</body>
</html>

index.js:

import img from './assets/chira.jpg';
import "./main.css";

和main.css

body {
  background-color: darkblue;
}

这些是我的配置文件(我有一个用于开发和生产的个人,并且有一个共同的):

webpack.common.js:

const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');

module.exports = {
  entry: './src/index.js',

  devtool: "none",
  plugins: [
    new HtmlWebpackPlugin({
      template: './src/index.html'
    })
  ],
  module: {
    rules: [
      {
        test: /\.css$/,
        use: [
          'style-loader',
          'css-loader'
        ],
      },
      {
        test: /\.html$/,
        use: ["html-loader"]
      },
      {
        test: /\.(png|jpe?g|gif|svg)$/i,
        use: [
          {
            loader: 'file-loader',
            options: {
              name: '[name].[hash].[ext]',
              publicPath: 'assets',
              outputPath: 'assets/img'
            }
          }
        ]
      }
    ],
  },
};

webpack.dev.js:

const path = require('path');
const common = require("./webpack.common");
const merge = require('webpack-merge');

module.exports = merge(common, {
  mode: "development",
  devServer: {
    contentBase: path.join(__dirname, 'src'),
  },
  output: {
    filename: "main.js",
    path: path.resolve(__dirname, "dist")
  },
});

和webpack.prod.js:

const path = require('path');
const common = require("./webpack.common");
const merge = require('webpack-merge');


module.exports = merge(common, {
  mode: "production",
  output: {
    filename: "main.[contentHash].js",
    path: path.resolve(__dirname, "dist")
  },
});

但是,当我运行npm run build时,它将执行以下命令:

"build": "webpack --config webpack.prod.js"

我得到了带有资产/ img / [名称]。[哈希]。[ext]的预期dist文件夹,但是在我的index.html中,我没有得到预期的src标记:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Popular on Letterboxd</title>
</head>
<body>
  <img src="[object Module]" />
<script type="text/javascript" src="main.e55bd4ff82bf2f5cec90.js"></script></body>
</html>

我已经尝试解决该问题已有一段时间了,但是我似乎在任何地方都找不到正确的答案,到目前为止,我一直没有尝试过。如果有人遇到此问题可以解决他们的问题,或者有人对问题可能是什么以及我能做什么有任何线索,我将不胜感激。预先感谢!

如果文件加载器版本为5.0,则为。在文件加载器上添加另一个选项“ esModule:false”将解决此问题。

{
    test: /\.(png|jpe?g|gif|svg)$/i,
    use: [
      {
        loader: 'file-loader',
        options: {
          name: '[name].[hash].[ext]',
          publicPath: 'assets',
          outputPath: 'assets/img',
          esModule: false
        }
      }
    ]
  }
