【问题标题】:Converting Web app into Desktop app with Electron使用 Electron 将 Web 应用程序转换为桌面应用程序
【发布时间】:2016-12-04 21:15:35
【问题描述】:

嘿,我是网络开发人员,我想为桌面制作应用程序。我发现了名为 Electron 的程序,我从这个页面下载了它:electron.atom.io

接下来我创建了运行此应用所需的文件:

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>

然后是 main.js:

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

// 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(url.format({
    pathname: path.join(__dirname, 'index.html'),
    protocol: 'file:',
    slashes: true
  }))

  // 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 macOS 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 macOS 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.

和 package.json:

{
  "name"    : "Test-App",
  "version" : "0.1.0",
  "main"    : "main.js"
}

现在当我输入 CMD

电子。

我得到了错误

'electron' 未被识别为内部或外部命令, 可运行的程序或批处理文件。

有没有什么方法可以在没有 CMD 的情况下从安装的应用程序运行这个程序,或者我该如何解决这个问题?

【问题讨论】:

  • 您是否在全球范围内安装了电子? npm install -g electron
  • 我用安装程序安装了电子,而不是用 npm @devilfart
  • @S.Mi Electron 没有安装程序,它是通过 NPM 分发和安装的。您可能下载并安装了 Electron API Demos 应用程序,其中包含 Electron API 的演示。
  • 是的,这是我下载的 Electron 的名称,但我如何通过 npm 安装它? @Vadim Macagon

标签: electron


【解决方案1】:

欢迎使用 stackoverflow!

您安装的包是一个演示包,旨在向开发人员展示 Electron 提供的不同功能。目前不适合您的需求。

正如devilfart 和Vadim 指出的那样,您需要的是Electron 运行时的全局安装。这可以通过启动具有管理权限的命令行并输入以下命令来实现:

npm install -g electron

这会将 Electron 运行时作为全局包安装在您的基本 node_modules 目录中,并启用 electron 命令。
