应用程序spyder启动可能已产生Windows 7错误

Question

我正在尝试启动Spyder，但似乎存在应用程序启动错误。我该如何解决？

我已经运行了以下命令：

conda remove spyder-kernels

conda install spyder-kernels=0.*

但是他们没有用。

这就是我得到的：

Traceback (most recent call last):
File "C:\Anaconda\Scripts\spyder-script.py", line 10, in 
sys.exit(main())
File "C:\Anaconda\lib\site-packages\spyder\app\start.py", line 186, in main
from spyder.app import mainwindow
