Question

我正在尝试创建一个故事书测试，该测试在使用typescript，babel和webpack的模块中使用react组件。我的地图反应组件参考并使用铯和铯反应组件。

当我尝试运行start-storybook（纱线故事书）时，我收到一个错误：

ERROR in ./node_modules/requirejs/bin/r.js
Module parse failed: Unexpected character '#' (1:0)
You may need an appropriate loader to handle this file type.

如果我谷歌此错误＆＃39;模块解析失败。意外的角色＆＃39;＃＆＃39;。＃4603＆＃39;我在结果列表的顶部看到了类似的问题，这些问题提示了一些尝试。

添加自定义加载程序（参考4603）
尝试使用shebang loader（参考号4603/531）
不要测试（参考170）
此外，其中一个链接到jsonstream的一个非常相似的错误，可以通过谷歌搜索找到节点目标应该忽略hashbang＃2168＆＃39;

我的主要问题是：

我尝试使用自定义加载程序和shebang加载程序（参考2168），但似乎都不起作用。甚至可以解决这个错误并在故事书中运行？关于JSONstream的研究表明使用shebang加载器可以解决这个问题，而我只是没有正确配置。
假设shebang加载器是推荐的最佳解决方案，那么我在.storybook / webpack.config.js中可能做错了什么（显然我正在做的事情不起作用）。

我应该注意：

如果我不尝试使用打字稿加载程序，我可以使用故事书来运行我的Map组件。如果我将它添加到github的cesium-react项目副本中，我可以运行我的Map故事。
此处显示的我的地图组件已尽可能简化，以尝试识别和解决我的导入问题。但是，目的是我的实际Map组件将使用Typescript实现。

以下是我认为相关文件的摘要，但如果被问到，会很乐意发布其他文件或摘要。

.storybook / webpack.config.js

const genDefaultConfig = require('@storybook/react/dist/server/config/defaults/webpack.config.js');
module.exports = (baseConfig, env) => {
  const config = genDefaultConfig(baseConfig, env);
  config.module.rules.push({
    test: /\.(ts|tsx)$/,
    loader: require.resolve('ts-loader')
  });
  // Add shebang to try to workaround unexpected character error.
  config.module.rules.push({
    test: /node_modules\/cesium\/index\.js$/,
    loader: require.resolve('shebang-loader')
  });
  config.resolve.extensions.push('.ts', '.tsx');
  return config;
};

.storybook / config.js

import { configure } from '@storybook/react';

// automatically import all files ending in *.stories.js or *.stories.ts?x
const req = require.context('../stories', true, /.stories.(ts?x|js)$/);

//interates through all files in ../stories that match the regex above
//and adds them to list of stories to show
function loadStories() {
  req.keys().forEach((filename) => req(filename));
}

configure(loadStories, module);

故事/ map.stories.js

import * as React from 'react';
import Map from "../src/components/Map";
import { withInfo } from '@storybook/addon-info';
import { storiesOf } from '@storybook/react';
storiesOf("Map", module)
  .add('Sample Map',
    withInfo('Map Stuff')(() =>
      <Map />
  ));

的src /组件/ Map.js。如果我在Map.js中取消注释我的cesium-react导入，则会发生错误。

import * as React from 'react';
// Uncomment to see unexpected character error.
import { Viewer } from "cesium-react";
export default class Map extends React.Component {
  render() {
    return (
      <div>hello</div>
    );
  }
}

Answer 1

我不知道你的webpack配置，这对我来说很奇怪，而我以前也没有看到它，但实际上你需要shebang-loader所以如果你使用npm 1}}运行：

npm install --save shebang-loader

如果您使用yarn，请运行：

yarn add shebang-loader

之后你必须在你的加载器中放入use密钥并在其中加载几个加载器，我想你的代码如下所示：

    const genDefaultConfig = require('@storybook/react/dist/server/config/defaults/webpack.config.js');
    module.exports = (baseConfig, env) => {
      const config = genDefaultConfig(baseConfig, env);
      config.module.rules.push({
        test: /\.(ts|tsx)$/,
        use: [
            {
               loader: require.resolve('ts-loader')
            },
            {
               loader: 'shebang-loader'
            }
        ]
      });
      // Add shebang to try to workaround unexpected character error.
      config.module.rules.push({
        test: /node_modules\/cesium\/index\.js$/,
        loader: require.resolve('shebang-loader')
      });
      config.resolve.extensions.push('.ts', '.tsx');
      return config;
    };

就我而言，它变得如下：

    module: {
        rules: [
            {
                test: /\.(js|jsx)$/,
                exclude: /(node_modules\/)/,
                use: [
                    {
                        loader: 'babel-loader'
                    },
                    {
                        loader: 'shebang-loader'
                    }
                ]
            }
       ]
    }

希望它对你有所帮助。

Answer 2

我创建了这个webpack.config.js来自己解决该问题：

   var path = require('path');


module.exports = {
  entry: './src/root.jsx',
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: 'bundle.js'
  },
module: {
   loaders: [
     {
       test:  /\.js$/,
       loader: 'shebang-loader'
     }
   ]
 }
}

如何使用Shebang Loader配置Webpack以忽略Hashbang将Cesium React组件导入Typescript React组件
