我正在使用Blessed库来构建一个简单的终端应用程序。
我的应用程序基于以下简单的示例编辑器构建：https ://github.com/jquast/blessed/blob/master/bin/editor.py
警告：以下步骤会破坏你的 IPython，我不知道如何修复它！
出于这个问题的目的，我将只使用editor.py. 让我们进行一些更改以允许调试：
1)import ipdb
2) 装ipdb.set_trace()上line 224
立即运行editor.py：python editor.py。应产生以下错误：
Traceback (most recent call last):

If you suspect this is an IPython bug, please report it at:
https://github.com/ipython/ipython/issues
or send an email to the mailing list at ipython-dev@scipy.org
You can print a more detailed traceback right now with "%tb", or use "%debug"
to interactively debug it.
Extra-detailed tracebacks for bug-reporting purposes can be enabled via:
c.Application.verbose_crash=True
现在，每当通过执行ipython命令运行 IPython 时，都会产生以下错误：
Traceback (most recent call last):
File "/usr/bin/ipython", line 5, in <module>

所以，IPython 似乎在全球范围内被打破了。我在 Cygwin 和 Ubuntu 上都遇到了这个问题。
怎么了？
