Question

我试图提示“打开文件”对话框，并在electron docs中找到了dialog.showOpenDialog(...)。

我现在将该行添加到了几个不同的项目中，结果该行一经崩溃便崩溃了。我会看到文件浏览器对话框窗口打开了一秒钟，然后崩溃了。控制台没有显示任何错误消息，它显示的最后一句话是Promise { <pending> }。

我尝试过的事情：

在official vscode debugging示例中添加dialog.showOpenDialog(...)，以查看是否发现任何错误。一旦到达该行，它总是崩溃，没有错误消息。
使用npm install electron --save-dev删除我的node_modules文件夹并重新安装electronic
使用全局电子命令electron .
使用npm uninstall -g electron和本地npm start卸载全局电子
使用`npm outdate
使用--disable-gpu参数

我正在使用Ubuntu 19.04，而不是VM，但是我也在Ubuntu 18.04的VM中对其进行了测试。

一个有趣的注意事项是，当我尝试使用带有type = file的html表单按钮来完成同一任务时，在打开文件浏览器对话框后，它也崩溃了电子应用程序。但是，当我在常规的网络浏览器中打开html页面时，它确实起作用了。

这是我的main.js

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

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

  // and load the index.html of the app.
  win.loadFile('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
  })

  const { dialog } = require('electron')
  console.log(dialog.showOpenDialog({ properties: ['openFile', 'multiSelections'] })) //*****THIS LINE HERE
}

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.

这是我的package.json
