javascript - Electron: app.on ('ready' ) 永远不会被调用

Question

我正在尝试使用 TypeScript 和 webpack 运行 electron 应用程序。
我有这个 main.ts 文件和已编译的 main.js 文件。

我编辑了 main.js 以便我可以查看是否调用了 ready。

主要.ts

import { app, BrowserWindow } from 'electron';
import * as url from 'url';
import * as path from 'path';

let win: Electron.BrowserWindow = null;


console.log('start');
console.log(app.isReady);
app.on('ready', () => {
  console.log('ready');
  win = new BrowserWindow({ width: 800, height: 600 });
  win.loadURL(url.format({
    pathname: path.join(__dirname, '../', 'no.html'),
    protocol: 'file:',
    slashes: true,
  }));
});

主要.js

console.log('main.js -- start');
exports.ids = [3];
exports.modules = {

/***/ 18:
/***/ (function(module, exports, __webpack_require__) {

"use strict";

Object.defineProperty(exports, "__esModule", { value: true });
const electron_1 = __webpack_require__(19);
const url = __webpack_require__(20);
const path = __webpack_require__(21);
let win = null;
console.log('before ready');
electron_1.app.on('ready', () => {
    console.log('ready');
    win = new electron_1.BrowserWindow({ width: 800, height: 600 });
    win.loadURL(url.format({
        pathname: path.join(__dirname, '../', 'index.html'),
        protocol: 'file:',
        slashes: true,
    }));
});


/***/ }),

/***/ 19:
/***/ (function(module, exports) {

module.exports = require("electron");

/***/ }),

/***/ 20:
/***/ (function(module, exports) {

module.exports = require("url");

/***/ }),

/***/ 21:
/***/ (function(module, exports) {

module.exports = require("path");

/***/ })

};;
console.log('main.js -- finish');

当我运行 ./node_modules/.bin/electron . 时，我的控制台显示

> electron .

main.js -- start
main.js -- finish

什么也没有发生。不会打开任何窗口。

这是我的文件夹结构。

.
├── build
│   ├── index.js
│   └── main.js
├── index.html
├── package.json
├── src
│   ├── index.ts
│   └── main.ts
└── webpack.config.js

我还在我的 package.son 文件上写了 "main": "build/main.js",。

我的环境

操作系统:Mac 10.10.5
Electron :1.6.11
节点:v8.2.1
网络包:3.0.0

感谢阅读。我将不胜感激!

附言 这是我的 webpack 配置文件。

const path = require('path');
const webpack = require('webpack');
module.exports = {
  entry: {
    main: './src/main.ts',
    index: './src/index.ts',
    template: './src/memo.vue',
    memo: './src/memo.vue'
  },
  output: {
    path: __dirname + '/build',
    filename: '[name].js'
  },
  plugins: [
    new webpack.optimize.CommonsChunkPlugin({
      name: 'common'
    })
  ],
  target: 'electron-main',
  resolve: {
    extensions: ['.ts', '.vue', '.js'],
    modules: ["node_modules"],
    alias: {
      vue: 'vue/dist/vue.js'
    }
  },
  module: {
    rules: [
      {
        test: /\.ts$/,
        include: [path.resolve(__dirname, 'src')],
        exclude: [path.resolve(__dirname, 'node_modules')],
        loader: 'ts-loader'
      },
      {
        test: /\.vue$/,
        include: [path.resolve(__dirname, 'src')],
        exclude: [path.resolve(__dirname, 'node_modules')],
        loader: 'vue-loader'
      }
      ,
      {
        test: /\.ts$/,
        include: [path.resolve(__dirname, 'src')],
        exclude: [path.resolve(__dirname, 'node_modules')],
        enforce: 'pre',
        loader: 'tslint-loader',
        options: {
          fix: true
        }
      }
    ]
  },
  node: {
    __dirname: false
  }
}

我认为您没有正确使用 webpack 包及其入口点。以下 Works For Me™。

webpack.config.js

const path = require('path');

module.exports = {
  entry: "./index.ts",
  output: {
    path: __dirname,
    filename: "index.js",
  },
  module: {
    rules: [{
      test: /\.ts$/,
      exclude: [/node_modules/],
      loader: "ts-loader"
    }]
  },
  resolve: {
    modules:[
      "node_modules"
    ],
    extensions: [".ts", ".js", ".json"]
  },
  target: "electron-main"
}

index.ts

import * as electron from 'electron';

electron.app.on('ready', function () {
  console.log("electron's body is ready... ");
})

package.json

{
  "devDependencies": {
    "devtron": "^1.4.0",
    "ts-loader": "^2.3.2",
    "typescript": "^2.4.2",
    "webpack": "^3.4.1"
  },
  "dependencies": {
    "electron": "^1.6.11"
  },
  "scripts": {
    "dev": "electron ."
  }
}

tsconfig.json

{
  "compilerOptions": {
    "target": "es2015",
    "moduleResolution": "node",
    "module": "commonjs"
  },
  "exclude": [
    "node_modules"
  ]
}

即使我做了一个额外的文件 main.ts 的额外步骤和 import "./main.ts"在index.ts它仍然有效。
