启动spyder:ImportError:无法导入名称“quick\u guide”

Question

当我启动spyder时，内部控制台弹出并给出以下“回溯”：

>>> WARNING:traitlets:kernel died: 6.001837253570557
Traceback (most recent call last):
  File "C:\...\lib\site-packages\traitlets\traitlets.py", line 528, in get
    value = obj._trait_values[self.name]
KeyError: 'banner'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:\...\lib\site-packages\qtconsole\base_frontend_mixin.py", line 163, in _dispatch
    handler(msg)

    value = self._validate(obj, dynamic_default())
  File "C:\...\lib\site-packages\spyder\widgets\ipythonconsole\shell.py", line 280, in _banner_default
    return self.long_banner()
  File "C:\...\lib\site-packages\spyder\widgets\ipythonconsole\shell.py", line 91, in long_banner
    from IPython.core.usage import quick_guide
ImportError: cannot import name 'quick_guide'

IPython控制台工作正常，只是缺少“简介文本”（python版本，help命令）。在

我可以忽略这个异常吗？还是有办法手动修复它？在

Answer 1

要手动修复异常，需要更改回溯中最后提到的文件。在这种情况下：

  File "C:\...\lib\site-packages\spyder\widgets\ipythonconsole\shell.py", line 91, in long_banner
    from IPython.core.usage import quick_guide
ImportError: cannot import name 'quick_guide'

并将quick_guide更改为quick_reference as quick_guide。可能需要重新启动Spyder，但随后异常消失。在
