节点和ChromeDevTools中的V8版本?

时间:2011-07-29 15:31:04

标签: eclipse node.js v8 google-chrome-devtools

我的主要问题是:

  1. 我从节点0.4.10开始运行什么版本的V8?
  2. 如何判断此版本是否与Eclipse中的ChromeDevTools 0.2.2兼容?
  3. 背景:我几乎得到了Eclipse working for debugging node.js remotely。事实上,它为一个简单的“Hello World”应用程序完美地工作(在添加服务器代理之后),但是当我向混合添加“express”时,它将无法正确连接。 Eclipse错误是:

      

    在以下期间发生内部错误:“调试会话初始化:   Remote NodeJS“。回调中发生异常

    ...我追踪到this source code的第61行(感谢“发生”的错误拼写。)

    我希望在继续前进之前消除版本偏差的可能性。

    编辑:从错误日志中挖出堆栈跟踪。嗯,也许我的服务器代理有编码问题?

repl中的

process.versions显示了以下信息:

> process.versions
{ node: '0.4.10', v8: '3.1.8.26', ares: '1.7.4', ev: '4.4', openssl: '1.0.0d' }

此处不应存在任何与版本相关的问题,至少在初始化阶段。 V8调试协议的发展非常缓慢。

不幸的是,你引用的信息太笼统了。你认为你可以在某处找到堆栈跟踪吗?该消息可能有“详细信息”按钮(但您可能会发现它),通常也会记录异常。您可以尝试打开“General-&gt; Error Log”视图(在大多数Eclipse配置中都可用),或者您可以查看Eclipse工作区中的文件:/.metadata/.log。 该代码表示​​存在错误消息中缺少的原因异常。

感谢您提供拼写错误报告。 :)
