使用node-inspector调试node.js [英] debugging node.js with node-inspector

问题描述

我正在尝试使用node-inspector调试我的nodejs应用程序.但是Google Chrome不会显示该代码.

I'm trying to debug my nodejs app using node-inspector. But Google Chrome doesn't show the code.

我正在使用以下内容

Node.js:v0.10.26

Node.js : v0.10.26

快递:4.0.0

节点检查器:v0.7.3

Node Inspector : v0.7.3

Google Chrome版本:34.0.1847.131

Google Chrome version : 34.0.1847.131

这就是我启动调试器的过程.

This is what I'm doing to start the debugger..

$ node-inspector
Node Inspector v0.7.3
Visit http://127.0.0.1:8080/debug?port=5858 to start debugging.

在另一个控制台中，

$ node --debug app.js 
debugger listening on port 5858
$

然后启动Google Chrome浏览器并转到

Then started Google Chrome and went to

http://127.0.0.1:8080/debug?port=5858

它打开了节点检查器，但是没有任何代码..所有窗口都是空的.

It opens up node-inspector but without any code..all windows are empty.

注意到我没有收到"Express服务器在端口3000上监听"

Noticed that I'm not getting 'Express server listening on port 3000'

根据 node-inspector无法连接到节点无法解决我所缺少的内容.希望您有什么建议..所以我可以在Google Chrome中调试Node.js应用.

Couldn't work out what I'm missing. Would be great of you have any suggestions..so I can debug my Node.js apps in Google Chrome.

推荐答案

尝试运行node --debug-brk app.js而不只是--debug.在节点检查器挂接到节点进程之前，您的应用程序可能不会暂停.使用--debug-brk将迫使节点在应用程序的第一行中断，并等待调试器附加到该进程.加载节点检查器Web界面是导致节点检查器附加到您的节点进程的原因.这就是为什么在查询字符串(localhost:8080/debug?port = 5858)中包含节点调试端口的原因.您是在告诉节点检查器它应该伸出并连接到哪个端口.

Try to run node --debug-brk app.js instead of just --debug. Your application may not be pausing before node inspector hooks into the node process. Using --debug-brk will force node to break on the first line of your app and wait for a debugger to attach to the process. Loading the node-inspector web interface is what causes node-inspector to attach to your node process; that's why you include the node debug port in the query string (localhost:8080/debug?port=5858). You're telling node-inspector what port it should reach out and attach to.

这是我放在一起的动画gif，展示了Node-inspector的完整安装和运行.

Here's an animated gif I put together showing a complete install and run of node-inspector.

在gif中，我使用--debug标志，因为我没有调试任何在启动时就可以运行的代码.我在请求处理程序内调试，该处理程序仅在请求页面时才触发.因此，刷新页面会导致节点检查器在该行中断.

In the gif I use the --debug flag because I'm not debugging any code that runs right at startup. I'm debugging inside a request handler, which only fires when the page is requested. Thus, refreshing the page causes node-inspector to break on that line.

不久前，我还整理了15分钟的YouTube教程.

I also put together a 15 minute YouTube tutorial a while ago.
