在 Electron-Typescript 应用程序中找不到模块 'jsonfile/utils'

Question

我从一个全新的工作非常简单的 Electron-Typescript 应用程序开始。

在这个非常简单的 Electron-Typescript 应用程序中，我添加了 main.ts:

import Ipfs from 'ipfs';
import IpfsHttpClient from 'ipfs-http-client';

并且这个 import 的 ipfs 模块运行良好。

但是当我添加

const { globSource } = IpfsHttpClient;

或

当我创建 IPFS 节点时：

const ops = async () => {
  const node = await Ipfs.create({ repo: String(Math.random() + Date.now()) });
}

我收到这个错误：

A JavaScript error occurred in the main process

tools/webpack/webpack.main.js :

module.exports = {
  entry: ['./src/main.ts'],
  // Put your normal webpack config below here
  module: {
    rules: require('./webpack.rules'),
  },
  resolve: {
    extensions: ['.js', '.ts', '.jsx', '.tsx', '.css', '.json'],
    alias: require('./webpack.aliases'),
  },
  target: 'electron-main'
};

tools/webpack/webpack.renderer.js :

/* eslint-disable @typescript-eslint/no-var-requires */
const rules = require('./webpack.rules');
const plugins = require('./webpack.plugins');
const aliases = require('./webpack.aliases');

module.exports = {
  target: 'electron-renderer',
  module: {
    rules,
  },
  plugins: plugins,
  resolve: {
    extensions: ['.js', '.ts', '.jsx', '.tsx', '.css'],
    alias: {
      // React Hot Loader Patch
      'react-dom': '@hot-loader/react-dom',
      // Custom Aliases
      ...aliases,
    },
  },
};

tools/webpack/webpack.rules.js :

const inDev = process.env.NODE_ENV === 'development';

module.exports = [
  {
    // Add support for native node modules
    test: /\.node$/,
    use: 'node-loader',
  },
  {
    // Typescript loader
    test: /\.tsx?$/,
    exclude: /(node_modules|\.webpack)/,
    use: {
      loader: 'ts-loader',
      options: {
        transpileOnly: true,
      },
    },
  },
  {
    // CSS Loader
    test: /\.css$/,
    use: [{ loader: 'style-loader' }, { loader: 'css-loader' }],
  },
  {
    // Less loader
    test: /\.less$/,
    use: [
      { loader: 'style-loader' },
      { loader: 'css-loader' },
      { loader: 'less-loader' },
    ],
  },
  {
    // Images Loader
    test: /\.(gif|jpe?g|tiff|png|webp|bmp)$/,
    use: [
      {
        loader: 'file-loader',
        options: {
          publicPath: 'images',
          outputPath: inDev ? 'images' : './main_window/images',
        },
      },
    ],
  },
];

如果修改target from electron-renderer' to web'中 tools/webpack/webpack.renderer.js :

/* eslint-disable @typescript-eslint/no-var-requires */
const rules = require('./webpack.rules');
const plugins = require('./webpack.plugins');
const aliases = require('./webpack.aliases');

module.exports = {
  //target: 'electron-renderer',
  target: 'web',
  module: {
    rules,
  },
  plugins: plugins,
  resolve: {
    extensions: ['.js', '.ts', '.jsx', '.tsx', '.css'],
    alias: {
      // React Hot Loader Patch
      'react-dom': '@hot-loader/react-dom',
      // Custom Aliases
      ...aliases,
    },
  },
};

并且在渲染器进程中 /src/app/components/App.tsx 我添加：

import Ipfs from 'ipfs';
const { globSource } = Ipfs;

const ops = async () => {
    const node = await Ipfs.create({ repo: String(Math.random() + 
Date.now()) });
    console.log('Ipfs node is ready');
    const files = [
      {
        path: '/home/marco/Downloads/Art21Costituzione.jpg',
        content: 'Art21Costituzione'
      },
      {
        path: '/home/marco/Downloads/VitaminaCAlimenti.pdf',
        content: 'VitaminaCAlimenti'
      }
    ];

    let results = await all(node.addAll(files));
    results.map(result => console.log(result));
}

我得到了这个正确的输出：

但是渲染器进程中的globSource报错：

for await (const file of node.addAll(globSource('/home/marco
/Downloads', globSourceOptions), addOptions)) {
  console.log(file);
}

所以..我想在 webpack 配置中需要修复一些东西才能让它在主进程中工作，而不是在渲染器进程中。

如何解决问题？

Answer 1

您可以使用webpack-config-utils模块来解决这个问题。

npm install --save-dev webpack-config-utils

详细说明已描述here

Answer 2

只需安装 jsonfile

yarn add jsonfile

对我有用！ https://www.npmjs.com/package/jsonfile
