Yeo*_*jie 4 python decorator ipython
我尝试导入 IPython 时出错，该错误似乎指向decorator.py 并输出此错误：
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)
我正在 conda 环境中运行带有 IPython 5.8 和装饰器 5.1 的 python 2.7，具有以下依赖项：

你可以将装饰器降级到4.xx
conda install decorator=4.4.1
