【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
