问题描述
安装PyReadline后,IPython无法正常工作。当我卸载它时,它再次开始工作。
After I installed PyReadline, IPython won't work. When I uninstalled it, it starts working again.
ipython的堆栈跟踪:

推荐答案
在他们的网站上, PyReadline
库用于 Windows 。
As stated on their site, the PyReadline
library is Used for Windows.
查看堆栈跟踪的最后几行:
Looking at the last lines of your stack trace:
import ctypes.wintypes as wintypes
File "/usr/local/lib/python2.7/ctypes/wintypes.py", line 23, in <module>
class VARIANT_BOOL(_SimpleCData):
ValueError: _type_ 'v' not supported
它试图从 ctypes
导入特定于Windows的数据类型,这显然是不可能的,因为你没有运行Windows。
It is trying to import windows specific data types from ctypes
which is obviously not possible since you are not running Windows.
