ElectronJs：HellowWorld 应用程序未启动

Question

我已经开始使用 electron js hello world 应用程序 first application with electron

我完全按照指示去做。

创建了 3 个文件main.js, index.html, package.json

package.json

    {
  "name"    : "your-app",
  "version" : "0.1.0",
  "main"    : "main.js"
    }

main.js

const electron = require('electron');
// Module to control application life.
const {app} = electron;
// Module to create native browser window.
const {BrowserWindow} = electron;

// 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 win;

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

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

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

  // Emitted when the window is closed.
  win.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.
    win = 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 (win === 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 require them here.

index.html

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8">
    <title>Hello World!</title>
  </head>
  <body>
    <h1>Hello World!</h1>
    We are using node <script>document.write(process.versions.node)</script>,
    Chrome <script>document.write(process.versions.chrome)</script>,
    and Electron <script>document.write(process.versions.electron)</script>.
  </body>
</html>

然后安装 Electron Globaly

npm install electron-prebuilt -g

然后尝试运行使用

的应用程序

electron .

但什么也没有发生。这是结果

C:\Users\abc\Desktop\electrons>electron .

C:\Users\abc\Desktop\electrons>

--- 编辑

我已经尝试在 package.json 中添加脚本来启动 electron

{ ... "scripts":{"start":"electron main.js"} ... }

然后当我运行应用程序使用 npm start 这是结果

C:\Users\abc\Desktop\electrons>npm start

> your-app@0.1.0 start C:\Users\abc\Desktop\electrons
> electron main.js

Answer 1

该代码适用于我，因此它一定适合您的环境。尝试删除项目的 node_modules 文件夹 (rm -rf node_modules)，然后是 npm i，然后是 npm start（我假设您的 [=15= 中仍有开始任务） ]).

Answer 2

如果您使用的是 Electron 1.1.0 并且没有安装 VS2015，那么您可能缺少 VC++2015 runtime.
