iPython 给出意外关键字参数的错误 'inputhook'

Question

我使用 Miniconda 在新的 Mac 上安装了 Python 3，并进行了以下设置：

macOS 卡特琳娜 10.15.1
康达 4.7.12
Python 3.7.5
iPython 7.9.0

当我尝试在终端中运行 iPython 时，我收到以下错误：

Traceback (most recent call last):

    sys.exit(start_ipython())

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@python.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

该错误似乎与 __init__() 方法关键字参数 'inputhook' 有关。关于如何解决这个问题有什么建议吗？

Answer 1

可能是这个问题，或者一个新的相关问题，因为它应该被修复：https://github.com/ipython/ipython/issues/11962

降级 prompt_toolkit 对我们有效：conda install prompt_toolkit==2.0.10

编辑：如果可能！

Answer 2

使用小于或等于 7.9.0 的 IPython 版本时会发生此错误。因此，更好的选择是将您的 IPython shell 升级到版本 ipython-7.10.1，这也解决了问题：

$ conda update ipython
