此webpack配置文件.

this the webpack config file.

const webpack = require('webpack');
const path = require('path');

const extractSCSS = new ExtractTextPlugin('[name].styles.css');

const BUILD_DIR = path.resolve(__dirname, 'build');
const SRC_DIR = path.resolve(__dirname, 'src');

console.log('BUILD_DIR', BUILD_DIR);
console.log('SRC_DIR', SRC_DIR);

    ]
  }
};

请参见下面的图像.

我在这里想念什么?

先谢谢了.

推荐答案

首先，您应该像这样导入图像:

first of all , you should import your image like :

import MyImage from '../relative/path/to/your/image'

然后按以下方式使用它:

then use it like:

function App() {
  return (
    <div className="App">
      <img src={MyImage} alt='any kind of description'>
    </div>
  );
}
