iPython 为意外的关键字参数“inputhook”提供错误

Question

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

• macOS Catalina 10.15.1
• 康达 4.7.12
• 蟒蛇 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):

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。对于如何解决这个问题，有任何的建议吗？

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 对我们有用： conda install prompt_toolkit==2.0.10

编辑：如果可能的话，kmario23 的响应（升级 IPython 安装）现在更可取！

Answer 2

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

$ conda update ipython
