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

I was running ipython successfully on fedora 18 until now: I'm getting the following exception when trying to launch it:

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。

I tried to upgrade ipython to the latest version using pip, which did not help. Any solution or workaround is very much welcomed.

推荐答案

一般情况下的配置文件中的IPython商店历史记录〜/ .ipython / profile_default / history.sqlite 。读/写似乎有一个磁盘错误。
检查文件/文件夹的权限，必要时删除文件。

IPython store history in a profile generally in ~/.ipython/profile_default/history.sqlite. There seem to be a disk error reading/writting to it. Check the permissions of the file/folders, if necessary delete the file.
