Question

我在fedora 18上成功运行ipython直到现在：我在尝试启动时遇到以下异常：

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。任何解决方案或解决方法都非常受欢迎。

Answer 1

通常在~/.ipython/profile_default/history.sqlite中的配置文件中的IPython商店历史记录。读/写似乎有一个磁盘错误。检查文件/文件夹的权限，必要时删除该文件。

Answer 2

我在jupyter配置文件c.NotebookNotary.db_file = u':memory:'

中设置~/.jupyter/jupyter_notebook_config.py解决了这个问题

ipython：OperationalError：磁盘I / O错误
