Question

尝试通过storybook和Webpack@4.17.2启动mini-css-extract-plugin时遇到此错误。我使用mini-css-extract-plugin而不是extract-text-webpack-plugin，因为它不支持Webpack > 4.x.x

Any Ideas如何在不降级到Webpack <4.x.x的情况下解决此问题错误：

    ERROR in ./src/styles/styles.less
Module build failed: TypeError: Cannot read property 'thisCompilation' of undefined
    at NodeTemplatePlugin.apply (C:\Users\sbr\Documents\Github\my-app\node_modules\webpack\lib\node\NodeTemplatePlugin.js:19:18)
    at Object.pitch (C:\Users\sbr\Documents\Github\my-app\node_modules\mini-css-extract-plugin\dist\loader.js:79:51)

打包json内容：

Storybook webpack.config内容：

const ExtractTextPlugin = require('mini-css-extract-plugin');
const extractTextPlugin = new ExtractTextPlugin('src/styles/styles.less');

module.exports = {
  module: {
    rules: [
      {
        test: /\.css$/,
        use: ["style-loader", "css-loader"]
      },
      {
        test: /\.js$/,
        exclude: /node_modules/,
        use: "babel-loader"
      }, {
        test: /\.jsx?$/,
        exclude: /node_modules/,
        use: "babel-loader"
      },
      {
        test: /\.less$/,
        use: [ExtractTextPlugin.loader, 'css-loader','less-loader']
      }
    ]
  }
};

我认为SamVK在评论中提到了简短的答案。正如Storybook问题所指出的，需要做一些工作来使Storybook Webpack 4兼容。有一些解决方法，但是您的里程可能会有所不同。

截至2018年12月，您最好的选择是确保您使用的是最新版本的Webpack 4.x，Storybook 4.x，并确保您基于其他内容包括正确版本的babel核心和babel加载器您已经包括在内。
