节点和 ChromeDevTools 中的 V8 版本？

Question

我的主要问题是：

1. 我从节点 0.4.10 运行的是哪个版本的 V8？
2. 如何判断此版本是否与 Eclipse 中的 ChromeDevTools 0.2.2 兼容？

背景：我几乎得到了Eclipse working for debugging node.js remotely。事实上，对于一个简单的“Hello World”应用程序，它可以完美地工作（在添加服务器代理之后），但是当我将“express”添加到组合中时它不会正确连接。 Eclipse 错误是：

在“调试会话初始化： 远程NodeJS”。回调发生异常

...我追踪到this source code 的第 61 行（感谢“occured”的拼写错误。）

我想在继续之前消除版本偏差的可能性。

编辑：从错误日志中挖掘堆栈跟踪。嗯，我的服务器代理可能有编码问题？

Answer 1

repl 中的process.versions 揭示了这些信息：

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

Answer 2

这里不应该有任何与版本相关的问题，至少在初始化阶段是这样。 V8 调试协议的发展非常缓慢。

很遗憾，您引用的信息过于笼统。您认为您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->Error Log”视图（在大多数 Eclipse 配置中可用），或者您可以查看 Eclipse 工作区中的文件：/.metadata/.log。 该代码表明存在原因异常，错误消息中缺少该异常。

感谢您提供拼写错误报告。 :)
