Pycharm调试器可以在Ubuntu上运行，但不能在Windows上使用相同的代码

更新：这里正在跟踪问题

编辑：我可能不是唯一一个与此问题有关的人。我错过了今天发布的这篇文章，它看起来很相关：PyCharm调试器不起作用

以下是使用Pycharm Professional时在Windows 7和Ubuntu 14.04上均可正常运行的最小示例

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，最奇怪的部分是：在Ubuntu的Pycharm调试器上，我没有遇到任何问题。但是，在Window的Pycharm调试器中，我得到以下回溯（即使未调试时代码运行正常！）：

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.

我什至不知道应该如何开始调试，因为我从未见过这样的事情！这是什么意思，如果您的程序在运行时可以运行，而在尝试调试时却不能运行，而且可以在其他OS上正常调试，那意味着什么呢？这只能是Pycharm错误吗？上面的回溯与我在主程序中得到的不完全相同，但是与我可以得到的最接近。以下是我在完整程序中看到的回溯：

这是您的最小示例。只需复制并粘贴并单击ViewBox。如果您运行随机图像，则应显示该图像。但是，如果您调试它，它会炸毁。
