Python 3.x 如何解决spyder 3.7中控制台中的内核错误

我最近尝试在Spyder 3.7中运行我的代码，我的Ipython控制台显示以下错误，我的所有代码都是这样：

An error ocurred while starting the kernel

The error is:

Traceback (most recent call last):

我对spyder很陌生，我完全不知道如何解决这个问题。 我已经尝试卸载anaconda并再次安装，但相同的错误不断出现。。。

有人知道我如何解决这个问题吗？

（这里是Spyder维护人员）请关闭Spyder，打开Anaconda提示符，然后在那里运行

conda update--all

。那会解决你的问题的。谢谢！这就解决了问题！（此处为Spyder maintainer）请关闭Spyder，打开Anaconda提示符并在那里运行
