IMAGE:您可能需要一个合适的加载程序来处理此文件类型

问题描述 投票:11回答:3

我无法确定在ReactJS webpack中加载图像的正确加载器是什么,

你可以帮个忙吗?我收到此错误:

Module parse failed: /Users/imac/Desktop/fakeeh/imgs/logo.png Unexpected character '�' (1:0)
You may need an appropriate loader to handle this file type.

这是webpack配置:

const path = require('path');


module.exports = {
  // the entry file for the bundle
  entry: path.join(__dirname, '/client/src/app.jsx'),

  // the bundle file we will get in the result
  output: {
    path: path.join(__dirname, '/client/dist/js'),
    filename: 'app.js',
  },

  module: {

    // apply loaders to files that meet given conditions
    loaders: [{
      test: /\.jsx?$/,
      include: path.join(__dirname, '/client/src'),
      loader: 'babel-loader',
      query: {
        presets: ["react", "es2015", "stage-1"]
      }
    }],
  },

  // start Webpack in a watch mode, so Webpack will rebuild the bundle on changes
  watch: true
};

非常感激!!

我也遇到了这个问题,我找到了一个解决方法。

首先,您需要安装两个加载器(file-loader,url-loader)。例如$ npm install --save file-loader url-loader

如果你想支持CSS。确保安装样式加载器。例如,$ npm install --save style-loader css-loader

接下来,您更新webpack配置,请检查下面的示例配置。希望能帮助到你。

  module: {
    loaders: [{
      test: /.jsx?$/,
      loader: 'babel-loader',
      exclude: /node_modules/
    }, {
      test: /\.css$/,
      loader: "style-loader!css-loader"
    }, {
      test: /\.(jpe?g|png|gif|woff|woff2|eot|ttf|svg)(\?[a-z0-9=.]+)?$/,
      loader: 'url-loader?limit=100000' }]
  },

你可以使用file-loader。您需要先使用npm安装它,然后像这样编辑您的webpack配置

module: {

    // apply loaders to files that meet given conditions
    loaders: [{
      test: /\.jsx?$/,
      include: path.join(__dirname, '/client/src'),
      loader: 'babel-loader',
      query: {
        presets: ["react", "es2015", "stage-1"]
      }
    },
    {
      test: /\.(gif|svg|jpg|png)$/,
      loader: "file-loader",
    }],
  },

使用Webpack 3,您可以使用url-loader如下:

安装url-loader

npm install --save url-loader

然后,在您的Webpack配置中:

module.exports = {
  module: {
    rules: [
      {
        test: /\.(png|jpg|gif)$/i,
        use: [
          {
            loader: 'url-loader',
            options: {
              limit: 8192
            }
          }
        ]
      }
    ]
  }
}

最后,在你的代码中:

<img src={require('./path/to/image.png')} />
