Pycharm调试器在Ubuntu上工作，但Windows上没有相同的代码 [英] Pycharm debugger works on Ubuntu but not on Windows for identical code
问题描述
更新：正在跟踪的问题此处
编辑：我可能不是唯一有这个问题的人。我错过了这也是今天发布的，它看起来相关： PyCharm调试器不工作
I may not be the only one with this issue. I missed this which was also posted today and it looks related: PyCharm debugger doesn't work
以下是使用Pycharm Professional时的Windows 7和Ubuntu 14.04上运行正常的最小示例
Below is a minimal example that runs fine on both Windows 7 and Ubuntu 14.04 when using Pycharm Professional
PyCharm 2016.1
Build #PY-145.260, built on March 22, 2016
JRE: 1.8.0_60-b27 x86
JVM: Java HotSpot(TM) Server VM by Oracle Corporation
现在这个很奇怪的部分：在Ubuntu的Pycharm调试器上，我没有问题。但是，在Window的Pycharm调试器中，我得到以下回溯（即使代码在调试时运行正常）：
Now the uber-weird part: On Ubuntu's Pycharm debugger I get no issue. However, in Window's Pycharm debugger I get the following traceback (even though the code runs fine when not debugging!):
Traceback (most recent call last):
File "D:\Program Files (x86)\JetBrains\PyCharm 2016.1\helpers\pydev\pydevd.py", line 1530, in <module>
globals = debugger.run(setup['file'], None, None, is_module)
File "D:\Program Files (x86)\JetBrains\PyCharm 2016.1\helpers\pydev\pydevd.py", line 937, in run

我甚至不知道我应该如何开始调试因为我从来没有看到过这样的事情！如果您的程序在运行时工作，而不是当您尝试调试它，而且它在另一个操作系统上调试正常，这意味着什么？这可以只是一个Pycharm的bug吗？上面的回溯与我在主程序中得到的不完全相同，但是我能得到的最接近。以下是我完整程序中的回溯：
I don't even know how I'm supposed to start debugging since I've never seen something like this happen before! What in the world does it mean if your program works when you run it but not when you try to debug it and moreover that it debugs fine on another OS? Can this only be a Pycharm bug? The above traceback isn't exactly identical to what I get in my main program but is the closest I could get. Below is the traceback I see in my full program:
Backend TkAgg is interactive backend. Turning interactive mode on.

这是你的最小例子。只需复制并粘贴，然后单击ViewBox。如果您运行它，则应显示一个随机图像。但是如果你调试它，它会爆炸。
Here is your minimal example. Just copy and paste and click the ViewBox. A random image should appear if you run it. But if you debug it, it blows up.

推荐答案
在重新安装Pycharm并从头开始重新安装python包后解决了这个问题，除了这个时候使用python 64位（之前使用的是32位）。此外，我正在使用Continuum Analytics的python包管理器。我不再使用它，所以也可能是罪魁祸首。
The issue has been resolved after reinstalling Pycharm and setting up python packages again from scratch, except this time using python 64-bit (was using 32-bit before). Moreover, I was using Continuum Analytics's python package manager. I no longer use it so that might also have been the culprit.
这篇关于Pycharm调试器在Ubuntu上工作，但Windows上没有相同的代码的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
