Question

我试图在Ubuntu 18.10上使用Electron dialog.showOpenDialog（），但是该方法-使用时-立即关闭基于电子的应用程序。

简单使用dialog.showOpenDialog（）会导致应用崩溃。当我注释掉时，该应用程序可以正常运行。当我在Windows上使用相同的代码时，它可以工作。

这里有没有人有一些技巧，专门针对Ubuntu更改代码？

我尝试在运气不错的主进程和渲染进程中都使用该方法。本机对话框打开片刻，然后整个应用程序退出。

在主要过程中：

const { dialog } = require('electron')
...
dialog.showOpenDialog(
    {
      title: "Select a file",
      filters: [{ name: "All Files", extensions: ["*"] }]
    },
    fileNames => {     
      if (fileNames === undefined) {
        console.log("No file selected");        
      }
      ...
})
...

编辑：我尝试了一个非常简单的示例：

// Modules to control application life and create native browser window
const { app, BrowserWindow, ipcMain, dialog } = 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 mainWindow

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

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

  // Open the DevTools.
  // mainWindow.webContents.openDevTools()

  // Emitted when the window is closed.
  mainWindow.on('closed', function () {
    // 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.
    mainWindow = 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', function () {
  // 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', function () {
  // 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 (mainWindow === 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.
ipcMain.on('openFile', (event, path) => {
  dialog.showOpenDialog(function (fileNames) {
    // fileNames is an array that contains all the selected 
    if (fileNames === undefined) {
      console.log("No file selected");
    } else {
      console.log("fileNames", fileNames);
    }
  });
})

尝试使用默认的Ubuntu终端运行电子应用程序。我当时在使用VS Code终端，但根据this issue on Github

却发现有问题
