I have installed Anaconda and I use the conda environments and the conda command to install software.
When I type:
jupyter notebook --version
I get
/Users/cr517/anaconda/bin/python
/Users/cr517/.local/bin/jupyter
but it should have pointed to /Users/cr517/anaconda/bin/jupyter
gedit /Users/cr517/anaconda/bin/jupyter
/Users/cr517/anaconda/bin/jupyter
than make it /Users/cr517/anaconda/bin/jupyter
ls *jupyter*
many of these files have the hardcoded path which might be wrong which might be reason why you are able to open he ipynb but cannot create the cellbash Anaconda....sh -b -p "Users/cr517/anaconda"
*How to check iPython version
You can check it with conda list ipython
Simply you can try this:
jupyter --version
