ipython调试器：交互式pdb上的完全回溯？

我最近从ipython0.10切换到了ipython0.11。在ipython0.11中，当python调试器启动时（即使用

%pdb

），我只看到完整回溯的一小部分，而在ipython0.10中，我会看到完整回溯。据我所知，完整的回溯无法从pdb命令行直接访问-您可以使用“u”在其中导航，但无法直接看到它

那么，有没有办法显示完整的回溯？例如配置参数

或者，更有用的是，有没有办法让ipython只显示捕获的异常，而不是显示捕获的代码的位置

编辑：示例：

In [1]: pdb
Automatic pdb calling has been turned ON

In [2]: 1/0
> <ipython-input-2-05c9758a9c21>(1)<module>()
     -1 1/0

ipdb> q
---------------------------------------------------------------------------
ZeroDivisionError                         Traceback (most recent call last)
/Users/adam/<ipython-input-2-05c9758a9c21> in <module>()
----> 1 1/0

ZeroDivisionError: integer division or modulo by zero

[1]中的

：pdb
自动pdb呼叫已打开
在[2]中：1/0

-1 1/0
ipdb>q
---------------------------------------------------------------------------
ZeroDivisionError回溯（最近一次呼叫上次）
/Users/adam/in（）
----> 1 1/0
ZeroDivisionError：整数除法或模零除法

我想在将

q

从pdb中取出之前查看ZeroDivisionError

有没有办法让ipython只显示 捕获，而不是显示在代码中捕获的位置

您可以使用：

从：

sys.excepthook（类型、值、回溯）

此函数用于打印给定的回溯和异常 sys.stderr

当引发异常并取消捕获时，解释器调用 带有三个参数的sys.excepthook，异常类，异常 实例和一个回溯对象。在本周的互动会议中 在控件返回到提示符之前发生；在Python中 程序这发生在程序退出之前。处理 这样的顶级异常可以通过分配另一个异常来定制 三参数函数，用于

sys.excepthook

sys.\uuuuu显示钩子\uuuuuu

sys.\uuuuuuuuuuuuuuuuuuuuuuuuuuu除外

这些对象包含displayhook和的原始值 程序开始时的excepthook。它们被保存，以便 displayhook和excepthook可以恢复，以防它们发生错误 替换为破损的物体

您还可以尝试将

--xmode

选项设置为

Plain

消息的第二部分（-xmode）似乎是答案，但似乎不起作用。我试过所有3个modename，回溯看起来都一样。知道是什么原因吗？谢谢。不幸的是，这指出了ipython（我的副本？）中可能存在的错误：

$ipython--xmode=Plain警告：无法识别的别名：“xmode”，它可能没有任何效果。

但是，一旦进入ipython:

在[1]中：%xmode异常报告模式：Plain

工作正常。您可能需要构建ipython的干净副本（或使用easy_install/pip重新安装）。作为一种解决方法，您可以将该

%mode…

行作为init命令添加到~/.ipython/config文件中，并解决问题（希望如此）！这是IPython 0.11中的一个错误-回溯是在您离开调试器后打印的，而不是在调试器启动之前打印的。它将被固定为0.12（应该在圣诞节前发出）。
