javascript - 尽管关注了有关主题的所有堆栈溢出文章，但无法将 Electron 初始化为 Angular 项目，反之亦然

问题描述

所以我试图将一个电子项目初始化为一个角度项目。当我运行ng build --prod && electron .orng build --base-href ./ && electron .时，我会收到两个错误之一，具体取决于我放置电子 main.js 文件的位置。在 src 文件中，我收到错误：

Uncaught Exception:
/Users/jaredjackson/Programming/Git/cinema-center/src/main.js:1
import { app, BrowserWindow } from 'electron';
                                     ^^^^^^

SyntaxError: Cannot use import statement outside a module
at wrapSafe

这是我的 package.json 文件：

{
  "name": "cinema-center",
  "version": "0.0.0",
  "main": "src/main",
  "scripts": {
    "ng": "ng",
    "start": "ng build --prod && electron .",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e",
    "electron": "electron ."

当我将 main.js 文件放在根项目目录中并更新 package.json 时，我收到此错误：

Unable to find Electron app at /Users/jaredjackson/Programming/Git/cinema-center. Cannot find module '/Users/jaredjackson/Programming/Git/cinema-center/main.js'. Please verify that the package.json has a valid "main" entry

我也添加"type": "module",到包 .json 中，它不起作用。

我使用ng newandnpm install --save-dev electron以及npm install --save-dev -g electron. 我还尝试通过首先从 electron-forge 安装电子然后运行来重做它ng new。

这是我的 main.js 文件：

import { app, BrowserWindow } from 'electron';

// Handle creating/removing shortcuts on Windows when installing/uninstalling.
if (require('electron-squirrel-startup')) { // eslint-disable-line global-require
  app.quit();
}

// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
let mainWindow;

const createWindow = () => {
  // Create the browser window.
  mainWindow = new BrowserWindow({
    width: 800,
    height: 600,
  });

  // and load the index.html of the app.
  mainWindow.loadURL(`file://${__dirname}/index.html`);

  // Open the DevTools.
  mainWindow.webContents.openDevTools();

  // Emitted when the window is closed.
  mainWindow.on('closed', () => {
    // Dereference the window object, usually you would store windows
    // in an array if your app supports multi windows, this is the time
    // when you should delete the corresponding element.
    mainWindow = null;
  });
};

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.on('ready', createWindow);

// Quit when all windows are closed.
app.on('window-all-closed', () => {
  // On OS X it is common for applications and their menu bar
  // to stay active until the user quits explicitly with Cmd + Q
  if (process.platform !== 'darwin') {
    app.quit();
  }
});

app.on('activate', () => {
  // On OS X it's common to re-create a window in the app when the
  // dock icon is clicked and there are no other windows open.
  if (mainWindow === null) {
    createWindow();
  }
});

// In this file you can include the rest of your app's specific main process
// code. You can also put them in separate files and import them here.

我的节点版本是 v14.16.1，我的 npm 版本是 7.14.0。Angular Cli 是 11.2.14。

解决方案

electron 使用 CommonJS 模块，将 main.js 头文件更改为以下内容：

const { app, BrowserWindow } = require("electron");
const url = require("url");
const path = require("path");
