c# - 使用 PTVS 进行 IronPython 远程调试

Question

我已经在我的 C# 应用程序中成功实现了 IronPython。我将所有脚本存储在数据库中，并在需要时加载它们。现在我想用 PTVS 调试我的 Python 代码。但是当我尝试将远程调试器连接到我的应用程序时，visual studio 总是说我应该使用 ptvsd.enable_attach()。

1. 我想如果我为我的 Python 引擎启用 Debug模式就足够了
2. 如果我需要导入 ptvsd，我应该如何导入脚本(ini、ma​​in、...)我是否应该将它们也放入我的数据库中？<

我想不出这一点并尝试了很多，但没有任何效果。

编辑:我可以弄清楚如何使用 ptvsd，我必须“包含”ptvsd 模块:

//copied from: C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\Extensions\Microsoft\Python Tools for Visual Studio\2.0

string dir = Path.GetDirectoryName("C:\\Support\\Modules\\ptvsd");
ICollection<string> paths = myScriptEngine.GetSearchPaths();

if (dir != null && dir != "")
{
    paths.Add(dir);
}
else
{
    paths.Add(Environment.CurrentDirectory);
}

但是现在我在 os.py 中得到一个错误:

global name 'statvfs_result' is not defined

行内:

_copy_reg.pickle(statvfs_result, _pickle_statvfs_result,
    _make_statvfs_result)

编辑 2:似乎我可以忽略带有全局名称的错误消息。但现在我收到以下消息:

IronPython must be started with -X:Tracing and -X:Frames options to support PTVS remote debugging.

编辑 3:我使用以下代码解决了 Tracing and Frames 的错误:

        Dictionary<string, object> options = new Dictionary<string, object>();
        options["Debug"] = true;
        options["Tracing"] = true;
        options["Frames"] = true;
        myScriptEngine = Python.CreateEngine(options);

但现在我遇到了下一个问题，我无法将 visual studio 附加到我的应用程序，我总是收到以下错误消息:

Could not connect to remote Python process at 'localhost:5678'. Make sure that the process is running, and has called ptvsd.enable_attach()-

编辑 5我想我现在可以附加到流程中。但是当我在 visual studio 调试器窗口中单击刷新按钮时，visual studio 挂断并且程序不再有反应。

刷新按钮:

也许有人可以阻止我，谢谢!

假设进程在 localhost 上运行并且您调用了 ptvsd.enable_attach()，这可能是防火墙问题。您可能需要调整 Windows 防火墙以允许连接到该端口(我认为始终允许本地主机连接，但我不确定)。
