ipython: OperationalError: 磁盘 I/O 错误

Question

到目前为止，我一直在 fedora 18 上成功运行 ipython:尝试启动它时出现以下异常:

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

我尝试使用 pip 将 ipython 升级到最新版本，但没有帮助。非常欢迎任何解决方案或解决方法。

IPython 将历史记录存储在配置文件中，一般在 ~/.ipython/profile_default/history.sqlite 中。似乎有一个磁盘错误读取/写入它。检查文件/文件夹的权限，如有必要，删除文件。
