如何使pycharm调试器与ironpython一起工作？

我用pycharm已经有一段时间了， 自从上次发布以来，我无法让调试器运行 使用IronPython我用Python2.7和 3.4而且效果很好，我一直得到这个：

Traceback (most recent call last):
  File "C:\Program Files\JetBrains\PyCharm Community Edition 5.0.5\helpers\pydev\pydevd.py", line 2411, in <module>

我试着调试它，但我没有太多的python经验

有人能帮忙吗

将Ironpython升级到2.7.6.3版后，我也经历了同样的经历。 我已经降级到以前的稳定版本2.7.5，它解决了这个问题
