Question

当我启动spyder时，会弹出内部控制台并提供以下“追溯”：

>>> 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)
  File "C:\...\lib\site-packages\qtconsole\jupyter_widget.py", line 296, in _handle_kernel_info_reply
    super(JupyterWidget, self)._started_channels()
  File "C:\...\lib\site-packages\qtconsole\frontend_widget.py", line 617, in _started_channels
    self.reset(clear=True)
  File "C:\...\lib\site-packages\qtconsole\frontend_widget.py", line 661, in reset
    self._append_plain_text(self.banner)
  File "C:\...\lib\site-packages\traitlets\traitlets.py", line 556, in __get__
    return self.get(obj, cls)
  File "C:\...\lib\site-packages\traitlets\traitlets.py", line 535, in get
    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控制台没有问题，只是缺少“介绍文本”（python版本，帮助命令）。

我可以忽略此异常，还是有办法手动修复此问题？

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，这一个：

  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。可能需要重启Spyder但是Exception消失了。

Answer 2

（ Spyder开发人员）这是在Spyder 3.1.4 （刚刚发布）中修复的。请更新以修复它。

Answer 3

我解决了：

仅在您的 conda 环境中使用 conda install spyder=3.1.4。

问候。

启动spyder后：ImportError：无法导入名称'quick_guide'
