Eclipse+Node.js error when debugging: "Failed to connect to Standalone V8 VM connect timed out"
提问by Totty.js
Here is how I've done:
这是我的做法：
https://github.com/joyent/node/wiki/Using-Eclipse-as-Node-Applications-Debugger
https://github.com/joyent/node/wiki/Using-Eclipse-as-Node-Applications-Debugger
but in the image after "Now start making new debug configuration by clicking the “New” button:"
但是在“现在通过单击“新建”按钮开始进行新的调试配置之后的图像中：
my image is different.
我的形象是不同的。
However when I run the debug I get the "Failed to connect to Standalone V8 VM connect timed out" error;
但是，当我运行调试时，出现“无法连接到独立 V8 VM 连接超时”错误；
In the debug configuration I never set the main file to run when the server starts. so something must be missing...
在调试配置中，我从未将主文件设置为在服务器启动时运行。所以一定少了一些东西......
I have another little question...
我还有一个小问题...
when I run the "node --debug dbgtest.js" code it works... what I'm doing it wrong?
当我运行“node --debug dbgtest.js”代码时，它可以工作……我做错了什么？
thanks a lot
多谢

You are doing nothing wrong. Of course the debugger will fail to connect if you are not running your node --debug dbgtest.js, which defaults to port 5858. It simply can't connect then.
你没有做错任何事。当然，如果您没有运行您的node --debug dbgtest.js，调试器将无法连接，默认为端口 5858。它根本无法连接。
You can specify different ports: node --debug[=port] dbgtest.js, as it also says in the beginning of the wiki link.
您可以指定不同的端口：node --debug[=port] dbgtest.js，正如 wiki 链接的开头所说。

This is an issue with the latest versions of node being incompatible with the Eclipse JDST node.js debugger.
这是最新版本的 node 与 Eclipse JDST node.js 调试器不兼容的问题。
I get the same error in Eclipse when using node 8.9.4. Tried a lot of things in Eclipse, nothing worked.
使用节点 8.9.4 时，我在 Eclipse 中遇到相同的错误。在 Eclipse 中尝试了很多东西，没有任何效果。
So I tried a node.js release from mid-2016, version 4.8.7. This was released around the time when the Eclipse JSDT/node integration was announced (http://www.eclipse.org/community/eclipse_newsletter/2016/may/article3.php). That version of node.js works fine with the latest Eclipse releases.
所以我尝试了 2016 年年中的 node.js 版本，版本 4.8.7。这是在宣布 Eclipse JSDT/节点集成时发布的（http://www.eclipse.org/community/eclipse_newsletter/2016/may/article3.php）。该版本的 node.js 适用于最新的 Eclipse 版本。
It's probably something minor that is getting in the way. The latest version produces the message: "DeprecationWarning: node --debugand node --debug-brkare invalid. Please use node --inspector node --inspect-brkinstead." It's given as a warning, but perhaps this is what is the underlying issue, perhaps node.js gives up when seeing --debug. Unfortunately, I cannot see how this could be changed in Eclipse without changing the code.
这可能是一些小事阻碍了。最新版本会产生以下消息：“DeprecationWarning: node --debugand node --debug-brkare invalid。请使用node --inspectornode --inspect-brk代替。” 它是作为警告给出的，但也许这就是潜在的问题，也许 node.js 在看到 --debug 时放弃了。不幸的是，如果不更改代码，我无法看到如何在 Eclipse 中进行更改。
The latest version of node that works is version 7. Starting with 8.0.0, it does not work.
最新的node版本是7版本，从8.0.0开始就不行了。

With nodejs version 8 the old debug-interface was removed and a new interface took it's place that's controlled via --inspectinstead of --debug.
在 nodejs 版本 8 中，旧的调试接口被删除，一个新的接口取而代之，它通过--inspect而不是--debug.
AFAIK there is no eclipse plugin that uses the new interface. Debugging can now be done using the chrome-browser, just search the www for "Debugging Node.js with Google Chrome"
AFAIK 没有使用新界面的 eclipse 插件。现在可以使用 chrome-browser 进行调试，只需在 www 上搜索“Debugging Node.js with Google Chrome”
