使用 Webpack 和 Electron 使用绝对路径导入

Question

我正在尝试将具有绝对路径的文件导入到我的主电子线程中。

在电子主线程中导入代码：

import * as Test2 from 'app/main/tray.js';

我已将 resolve.root 添加到 webpack.config：

{
  module: {
    loaders: [{
      test: /\.jsx?$/,
      loaders: ['babel-loader'],
      exclude: /node_modules/,
    }, {
      test: /\.json$/,
      loader: 'json-loader',
    }],
  },
  output: {
    path: path.join(__dirname, 'dist'),
    filename: '[name]/index.js',
    libraryTarget: 'commonjs2',
  },
  resolve: {
    root: [
      path.resolve('./')
    ],
    extensions: ['', '.js', '.jsx'],
    packageMains: ['webpack', 'browser', 'web', 'browserify', ['jam', 'main'], 'main'],
  },
  plugins: [

  ],
  externals: [
    // put your node 3rd party libraries which can't be built with webpack here
    // (mysql, mongodb, and so on..)
  ],
};

当我运行 webpack 服务器时没有抛出错误（webpack 发现文件很好）但是当我运行 electron 时抛出错误。

看起来 electron 正在改变 webpack 的导入行为？这些文件在渲染器窗口中正确导入，而不是主线程...

Answer 1

你试过了吗：

root: [
     path.resolve(__dirname)
]

Answer 2

我的问题是我使用 webpack 构建电子渲染器，但没有使用 webpack 构建电子主线程。

我专门为主线程添加了一个新的 webpack.config - 现在我可以使用 webpack.root（但是现在所有代码都必须编译，这有点可惜......）
