排坑：TypeError: handle_get_file_code() got an unexpected keyword argument ‘save_all‘

一，报错现象

在安装或更新好spyder后，在运行之前的代码时，可能会出现如下报错信息：

This command failed to be executed because an error occurred while trying to get the file code from Spyder's editor. The error was:
An exception has occurred, use %tb to see the full traceback.
TypeError: handle_get_file_code() got an unexpected keyword argument 'save_all'

二，报错原因

此问题由更新spyder后内核版本冲突导致

三，解决

重装spyder-kernels1.9.3版本即可

conda install spyder-kernels=1.9.3
