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

问题描述

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 Map react 组件引用并使用了 cesium 和 cesium-react 组件.

I am attempting to create a storybook test that uses a react component in a module that uses typescript, babel, and webpack.My Map react component references and uses cesium and cesium-react components.

当我尝试运行 start-storybook(纱线故事书)时出现错误:

When I try to run start-storybook (yarn storybook) I get an error:

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.

@ multi ./node_modules/@storybook/react/dist/server/config/polyfills.js ./node_modules/@storybook/react/dist/server/config/globals.js (webpack)-hot-middleware/client.js?reload=

如果我用谷歌搜索这个错误模块解析失败.意外字符#".#4603' 我在结果列表的顶部看到类似的问题，建议尝试一些事情.

If I google this error 'Module parse failed. Unexpected character '#'. #4603' I see similar issues at the top of the result list that suggests a few things to try.

• 添加自定义加载器(参考 4603)
• 尝试使用 shebang 加载程序(参考 4603/531)
• 干脆不要测试(参考文献 170)
• 此外，其中一个链接到 jsonstream 的一个非常相似的错误，可以通过谷歌搜索节点目标应该忽略 hashbang #2168"找到

我的主要问题是:

1. 我曾尝试使用自定义加载器和 shebang 加载器(参考 2168)，但似乎都不起作用.甚至有可能解决这个错误并在故事书中运行吗?对 JSONstream 的研究表明，可以使用 shebang 加载程序解决问题，但我只是没有正确配置.
2. 假设shebang loader 是推荐的可能解决方案中最好的，那么我在.storybook/webpack.config.js 中可能做错了什么(显然我所做的不起作用).

我应该注意:

• 如果我不尝试使用 typescript 加载器，我可以使用 storybook 来运行我的 Map 组件.如果我将我的 Map 故事添加到 github 的 cesium-react 项目的副本中，我就可以运行它.
• 此处显示的我的 Map 组件已尽可能简化，以便尝试识别和解决我的导入问题.但是，目的是使用 Typescript 实现我的实际 Map 组件.

以下是我认为相关文件的片段，但如果被问到，我很乐意发布其他文件或片段.

Here are snippets of what I think are relevant files but would happily post other files or snippets if asked.

• .storybook/webpack.config.js

• .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

.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);

stories/map.stories.js

stories/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 />
  ));

src/components/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.

src/components/Map.js. The error will occur if I uncomment my cesium-react import in Map.js.

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>
    );
  }
}

package.json(片段，如果需要，我可以提供更多文件)

推荐答案

我不知道你的 webpack 配置，这对我来说很奇怪，我以前没见过，但实际上你需要 shebang-loader 所以如果你使用 npm 运行:

I don't know your webpack configuration, it is weird for me and I didn't see like it before, but actually you need shebang-loader so if you using npm run:

npm install --save shebang-loader

如果你使用yarn，那么运行:

And if you use yarn so run:

yarn add shebang-loader

之后你必须把 use 键放在你的加载器中并在里面加载几个加载器，我猜你的代码变成如下:

After it you must put use key in your loader and load several loader inside it, I guess your code become like below:

    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，它变成了如下所示:

In my case it became like below:

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