After starting spyder: ImportError: cannot import name 'quick_guide'

Question

当我启动 spyder 时，内部控制台弹出并给出以下 "traceback":

>>> 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)

    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 "introduction text"（python 版本，帮助命令）。

我可以忽略这个异常，还是有办法手动修复这个问题？

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：

  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，但随后异常消失了。

Answer 2

(Spyder 开发人员在这里) 这已在 Spyder 3.1.4（刚刚发布）中修复。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。

此致。
