我正在嘗試基於http://electron.atom.io/docs/tutorial/quick-start/的說明創建一個簡單的基於Electron的應用程序,其中提供了下面的代碼。當我試圖用電子1.4.4和6.7.0的NodeJS運行它,我得到:試圖運行基於電子的應用程序的問題?
TypeError: Cannot read property 'on' of undefined
at Object.<anonymous> (/path/to/proj/src/goelectron.js:29:4)
的代碼如下:
const {app, BrowserWindow} = require('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 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.
這表明,「應用」是不確定的,但我不熟悉提供const {app, BrowserWindow} = require('electron')
的符號,所以我不確定如何檢查是什麼錯誤?
您不應該在全局安裝'electron',而應該在運行'electron src/goelectron.js'的'package.json'中添加一個NPM腳本。 –
添加到package.json的建議非常有用 - 謝謝 –
