ipython调试器：交互式pdb上的完全回溯？

本文介绍了ipython调试器：交互式pdb上的完全回溯？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我最近从ipython0.10切换到ipython0.11。在ipython0.11中，我只看到python调试器参与时的完整回溯的小片段（即使用％pdb ），而在ipython0.10中，我会看到完全追溯。据我所知，pdb命令行无法直接访问完整的回溯 - 您可以使用'u'导航它，但无法直接看到它。 或者，更有用的是，有没有办法让ipython只显示被捕获的异常，而不是显示代码中的位置被抓了？ 编辑：示例： 在[1]中：pdb 自动pdb呼叫已开启 在[2]中：1/0 > < ipython-input-2-05c9758a9c21>（1）< module>（） -1 1/0 ipdb> q --------------------------------------------- ------------------------------ ZeroDivisionError Traceback（最近一次调用最后一次） / Users / adam /< IPython的输入-2-05c9758a9c21> in< module>（） ----> 1 1 $ ZeroDivisionError：整数除法或模数为零 I我希望在 q 之前看到ZeroDivisionError 从pdb中出来。解决方案 您可以使用 sys.excepthook ： import sys def exc_hook（类型，值，追溯）：打印类型 sys.excepthook = exc_hook 来自 sys 模块文档： 您也可以尝试启动ipython，并将 - xmode 选项设置为 Plain 来自 IPython参考：这里是一些示例用法。请注意每个回溯的行数差异： - xmode = Plain ： [19:55 jon @ hozbox~ / SO / python] $ ipython --xmode = Plain ipython-debugger-full- traceback-on-interactive-pdb.py ------------------------------------- ----------------------- Traceback（最近一次调用最后一次）：文件ipython-debugger-full-traceback-on -interactive-pdb.py，第2行，< module> 1/0 ZeroDivisionError：整数除法或模数为零 - xmode =上下文 ： [19 ：55 jon @ hozbox~ / SO / python] $ ipython --xmode =上下文ipython-debugger-full-traceback-on-interactive-pdb.py ------------- -------------------------------------------------- ------------ ZeroDivisionError Traceback（最近一次调用最后一次） / home / jon / SO / python / ipython-debugger-full-traceback-on -interactive-pdb.py in< module>（） 1 ----> 2＃！/ usr / bin / python 3 1/0 4 5 ZeroDivisionError：整数除法或模数为零 - xmode =详细 ： [19:54 jon @ hozbox~ / SO / python] $ ipython --xmode =详细ipython-debugger-full-traceback- on-interactive-pdb.py --------------------------------------- ------------------------------------ ZeroDivisionError Traceback（最近一次调用最后一次） /home/jon/SO/python/ipython-debugger-full-traceback-on-interactive-pdb.py in< module>（） 1 ---- > 2＃！/ usr / bin / python 3 1/0 4 5 ZeroDivisionError：整数除法或模数为零 并且未指定.py文件： - xmode =普通 ： [19:55 jon @hozbox~ / SO / python] $ ipython --xmode = Plain 在[1]中：1/0 --------------- --------------------------------------------- Traceback （最近的呼叫最后一次）：文件< ipython console>，第1行，< module> ZeroDivisionError：整数除法或模数为零 --xmode =上下文 ： [20:03 jon @ hozbox~ / SO / python] $ ipython --xmode =上下文 在[1]中：1/0 ------------------- -------------------------------------------------- ------ ZeroDivisionError Traceback（最近一次调用最后一次） / home / jon / SO / python /< ipython console> in< module>（） ZeroDivisionError：整数除法或模数为零 - xmode =详细 ： [20:01 jon @ hozbox~ / SO / python] $ ipython --xmode =详细 在[1]中：1/0 ---- -------------------------------------------------- --------------------- ZeroDivisionError Traceback（最近一次调用最后一次） / home / jon / SO / python / < ipython console> in< module>（） ZeroDivisionError：整数除法或模数为零 使用Python调试器。 I recently switched from ipython0.10 to ipython0.11. In ipython0.11, I only see a small snippet of the full traceback when the python debugger engages (i.e. using %pdb), whereas in ipython0.10 I'd see the full traceback. As far as I can tell, the full traceback is not directly accessible from the pdb command line - you can navigate through it with 'u' but can't see it directly.So, is there any way to show the full traceback? Such as a configuration parameter?Or, even more usefully, is there any way to have ipython just show the Exception that was caught, rather than showing where in the code it was caught?EDIT: Example:In [1]: pdbAutomatic pdb calling has been turned ONIn [2]: 1/0> <ipython-input-2-05c9758a9c21>(1)<module>() -1 1/0ipdb> q---------------------------------------------------------------------------ZeroDivisionError Traceback (most recent call last)/Users/adam/<ipython-input-2-05c9758a9c21> in <module>()----> 1 1/0ZeroDivisionError: integer division or modulo by zeroI'd like to see the ZeroDivisionError before q'ing out of the pdb. 解决方案 You could use sys.excepthook:import sysdef exc_hook(type, value, traceback): print typesys.excepthook = exc_hookFrom the sys module documentation:You can also try starting ipython with the --xmode option set to PlainFrom IPython reference:Here are some example usages.
