Anaconda 发行版 Python 错误

我的 Anaconda Python 安装似乎有问题。

当我通过 cmd 运行 Python 时，它可以工作，并且我也可以直接通过 cmd 运行 Python 程序，甚至导入 scipy、numpy、matplotlib 等。

但是，当我尝试使用 cmd 命令“ipython”运行 IPython 时，出现错误：

Traceback (most recent call last):

DatabaseError: database disk image is malformed

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 [email protected]

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

我认为错误是由于DatabaseError: database disk image is malformed错误引起的，但不确定这意味着什么。

有什么建议吗？

问题在于 SQLite 数据库损坏。在本例中是history.sqlite数据库。

请查看您的配置文件文件夹（或您在配置中设置的路径）是否可以找到文件history.sqlite。

如果您可以找到它，请先进行备份（以防万一您需要它），然后创建一个同名的新空文件（history.sqlite）。

现在尝试再次运行 IPython，您应该能够启动它。
