IPython（jupyter）中的完成现在可以工作了（意外的关键字参数'column'）

Question

我使用的是jupyter笔记本，它工作正常，但当我按TAB键时，自动完成功能不起作用。 我已经检查了StackOverflow中的所有类似案例，但没有一个解决方案适合我。 我也尝试过对：伊皮顿、伊皮克内尔、绝地和龙卷风进行“pip升级”，升级效果很好，但问题仍然存在。 我试过Firefox、Chrome和Edge。 当我按TAB键时，我可以在终端中看到这些错误：

[IPKernelApp] ERROR | Exception in message handler:

如果有人能帮我处理这个案子，我会很高兴的

Answer 1

@techno1731的解决方案是次优的，因为它只是禁用了绝地武士，而不是解决根本问题

最新的绝地（0.18）版本与IPython 7.19不兼容，请参见this discussion。IPython:7.20（于2020年2月1日发布）和8.0（尚未发布）有一个兼容性修复程序

此时正确的解决方法是升级IPython：

pip install -U "ipython>=7.20"

将来，在删除所有特定于您的安装的路径片段后，您可以搜索trackback的最后两行，这就是搜索：

     super().__init__(code, environment=environment,
TypeError: __init__() got an unexpected keyword argument 'column'

这将在今天的前两个Google结果中为您提供GitHub的相关问题

Note: this is a copy of my answer from Giant IPKernelApp Error Using Hydrogen in Atom question which indeed can appear unrelated given the Hydrogen/Atom setting. I will now vote to close all other questions on the topic as duplicate of this one.

Answer 2

不久前，当我在本地使用虚拟环境的机器上工作时，我在Jupyterlab遇到了同样的问题

这是一个绝地武士太慢（或者说要花很长时间）无法完成的问题，对我来说有效的方法是在笔记本顶部添加以下行（例如，你通常在导入的地方）：

# Jedi not working
%config Completer.use_jedi = False

这应该能奏效

Answer 3

我用的是以前版本的绝地武士：

pip install jedi==0.17

这对我很有用
