Spyder 3错误和UI加载不正确

Question

从Anaconda Navigator加载Spyder 3时遇到问题。一开始它给我一个错误，与Spyder 3图标集没有加载有关，它将恢复为Spyder 2。从那里它根本不会发射。通过使用“show console”从终端强制打开编辑器，但是图标集现在在顶部被切断，我无法访问任何下拉菜单： Missing Drop Downs

在不同的环境（包括根目录）中多次将Spyder重置为默认值，然后重新安装Anaconda后，我最终从Spyder内部控制台收到以下错误消息：

Spyder Internal Console

This console is used to report application internal errors and to inspect Spyder internals with the following commands: spy.app, spy.window, dir(spy)

Please don't use it to run your code

Traceback (most recent call last): File "C:\Users\Chapin23\AppData\Local\Continuum\anaconda3\envs\Python\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:

有人见过这样的事吗？在
