Cannot run jupyter notebook by python2.7

MacBook laptop

Have activated py27 in the terminal. When I tried to run jupyter notebook, it returned:

bash-3.2$ source activate py27
(py27) bash-3.2$ jupyter notebook
Traceback (most recent call last):
  File "/Users/xx/anaconda3/envs/py27/bin/jupyter-notebook", line 7, in <module>
    from notebook.notebookapp import main
  File "/Users/xx/anaconda3/envs/py27/lib/python2.7/site-packages/notebook/__init__.py", line 25, in <module>

    from decorator import decorator
  File "/Users/xx/anaconda3/envs/py27/lib/python2.7/site-packages/decorator.py", line 162
    print('Error in generated code:', file=sys.stderr)
                                          ^
SyntaxError: invalid syntax
(py27) bash-3.2$

How to solve this? Is it impossible to run python 2.7 in Jupyter right now?

I had the same issue.

    from decorator import decorator
  File "/home/hamza/miniconda3/envs/py27/lib/python2.7/site-packages/decorator.py", line 162
    print('Error in generated code:', file=sys.stderr)
                                          ^
SyntaxError: invalid syntax

I found that the installed "decorator" version (in my case decorator-5.1.0, i guess it was automatically installed with jupyter by conda) requires a Python>=3.5, while I had python 2.7.

all I did is reinstall decorator package to fit py27:

pip uninstall decorator

Successfully uninstalled decorator-5.1.0

pip install decorator

Successfully installed decorator-4.4.2
