python – Pycharm调试器适用于Ubuntu,但不能在Windows上使用相同的代码
作者：互联网
更新：跟踪问题here
编辑：我可能不是唯一有此问题的人.我错过了今天发布的这个看起来很相关：PyCharm debugger doesn’t work
下面是一个在使用Pycharm Professional时在Windows 7和Ubuntu 14.04上运行良好的最小示例
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
现在超级奇怪的部分：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(即使代码在不调试时运行正常！)：
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
pydev_imports.execfile(file, globals, locals) # execute the script

@QtCore.pyqtSlot(int, int)
AttributeError: 'module' object has no attribute 'pyqtSlot'
Backend TkAgg is interactive backend. Turning interactive mode on.
我甚至都不知道我应该如何开始调试,因为我以前从未见过这样的事情！如果您的程序在运行时工作,但是当您尝试调试程序时,它是什么意思,而且它在另一个操作系统上调试很好？这可能只是一个Pycharm bug吗？上面的回溯与我在主程序中得到的完全相同,但是我能得到的最接近.以下是我在完整程序中看到的回溯：

这是你的最小例子.只需复制并粘贴,然后单击ViewBox即可.如果运行它,则应出现随机图像.但如果你调试它,它会爆炸.

解决方法:
重新安装Pycharm并从头开始再次设置python包后问题已得到解决,除非这次使用python 64-bit(之前使用的是32位).而且,我使用的是Continuum Analytics的python包管理器.我不再使用它,因此也可能是罪魁祸首.
