javascript - webpack 未正确捆绑

Question

我正在使用 web pack 进行捆绑。我收到以下错误

TypeError: The value of the superclass's prototype property is not an object.

app.js

const MyOncogene = require('./my-oncogene');

require("../css/style.css");

new MyOncogene({})

my-oncogene.js

const Oncogene = require('./lib.oncogene');

module.export = class MyOncogene extends Oncogene {}

lib.oncogene.js

class Oncogene {}

webpack.config.js

const path = require('path');
const ExtractTextPlugin = require("extract-text-webpack-plugin");

module.exports = {
  entry: './src/js/app.js',
  output: {
    filename: 'app.js',
    path: path.resolve(__dirname, 'docs')
  },
   module: {
    rules: [
      {
        test: /\.css$/,
        use: ExtractTextPlugin.extract({
          fallback: 'style-loader',
          use: [ 'css-loader' ]
        })
      }
    ]
  },
  plugins: [
    new ExtractTextPlugin({
      filename: '[name].css'
    })
  ]
};

您没有导出 Oncogene 类。你应该在lib.oncogene的末尾写下:

module.exports = Oncogene; 

此外，在 my-oncogene 中，您正在编写 module.export 而不是 module.exports
