nbformat error trying to open jupyter notebook

I am trying to install Jupyter Notebook in macOS Mojave.

I have tryied with Anaconda but although anaconda3 is apparently well installed, with the correct path in my bash, I get: 

$ jupyter notebook
-bash: jupyter: command not found

I have also tried with

python3 -m pip install --upgrade pip

python3 -m pip install jupyter

but after I try to open jupyter notebook I get this error:

$ jupyter notebook
Traceback (most recent call last):
  File "/Users/danielavargasrobles/miniconda3/bin/jupyter-notebook", line 7, in <module>
    from notebook.notebookapp import main
  File "/Users/danielavargasrobles/miniconda3/lib/python3.6/site-packages/notebook/notebookapp.py", line 83, in <module>
    from .services.contents.manager import ContentsManager
  File "/Users/danielavargasrobles/miniconda3/lib/python3.6/site-packages/notebook/services/contents/manager.py", line 17, in <module>
    from nbformat import sign, validate as validate_nb, ValidationError
ModuleNotFoundError: No module named 'nbformat'

Does anyone have an idea of what is happening? Thank you!

Did you installed jupyter inside your envirnoment ? I had a similar issue, jupyter was launching because installed outside venv but not installed inside your envirnoment it will lead to nbformat issue.

conda activate your_env
conda install jupyter

should do the trick.
