IPython 'Error in generated code:', file=sys.stderr
Question
I have an error trying to import IPython, the error seems to point to the decorator.py and outputs this error:
from decorator import decorator
File "C:\Users\ASUS\miniconda3\envs\test\lib\site-packages\decorator.py", line 162
print('Error in generated code:', file=sys.stderr)
i am running python 2.7 with IPython 5.8 and decorator 5.1 from a conda environment with this dependencies:

The decorator staring with V5.xx, Requires: Python >=3.5
you can downgrade decorator to 4.xx
conda install decorator=4.4.1

Please update decorator to the version 5.1.1 : seems like there was a bug in 5.1.0 .
