我正试图从头开始从Visual Studio 2017(而不是vscode)调试电子应用程序。
我创建了一个控制台nodejs项目,安装并保存电子。项目结构:
app.js
的内容(取自电子网站):
'use strict';
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.
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>
然而,当我点击开始时,电子应用程序启动,但调试过程似乎自行分离。当我尝试手动将调试器连接到所有电子过程(Debug - &gt; Attach to process - &gt;选择所有电子过程)时,断点声称不会被命中,因为没有加载符号。
我错过了一步吗?由于可以在VSCode上进行调试,我认为它也可以在VS2017中完成?
非常感谢。
注意:我确实检查了抑制JIT优化并取消选中仅启用我的代码。

这实际上很容易做到。
转到调试&gt;附加到流程... 并输入 Webkit websocket 连接类型,并输入 http://127.0.0.1:5858 作为目标。
您的断点现已启用。

在“Node.exe选项”字段中,为NodeJS v6及更低版本添加--debug=$DEBUG_PORT
或为NodeJS v7或更高版本添加--inspect=$DEBUG_PORT
,其中$DEBUG_PORT
用于表示您指定的端口在你的调试配置中。
如果您没有传递端口并且只传递--debug
或--inspect
标志,则Node调试器分别侦听端口5858和9229 ......他们稍后将默认端口更改为9229节点的版本。
请告诉我这是否有帮助!

Attaching to and Debugging Electron - &gt;要启动调试会话,请打开PowerShell / CMD并执行Electron的调试版本,使用该应用程序作为参数打开。
$ ./out/D/electron.exe ~/my-electron-app/

要查看未加载符号的原因,请在Windbg中输入以下命令。
> !sym noisy
> .reload /f electron.exe
