Can't use Jupyter Notebook: jsonschema apparently missing

Question

When using a an Anaconda environment, I can\'t start Jupyter to work in a notebook. I can do so without the environment, but I need to be able to use the environment. Here

Answer 1

I had the same problem.

I solved it by running this command

conda install -c anaconda jsonschema

https://anaconda.org/anaconda/jsonschema

Answer 2

I think I have a solution.

I did may things, regenerated my env (anaconda env) from another computer where it worked, but no success.

What I think that nailed it is upgrading jsonschema to 2.5.1

Here are my steps from "bad" jupyter env to working jupyter env.

Good luck and come back if it doesn't work, I will post the notebook* relevant versions.

>conda upgrade pip
pip:        8.1.0-py27_0  --> 8.1.1-py27_0
setuptools: 20.2.2-py27_0 --> 20.3-py27_0 

>pip install functools32
Downloading functools32-3.2.3-2.tar.gz

>jupyter notebook
ImportError: No module named _version
Jupyter notebook format depends on the jsonschema package:
    https://pypi.python.org/pypi/jsonschema
Please install it first.

>pip install jsonschema

>pip install --upgrade jsonschema

Answer 3

Try this from terminal, it worked to me:

pip install --upgrade pyrsistent

Answer 4

I solved it by just uninstalling and reinstalling python 3.7

Answer 5

i also got the same error and none of the above mentioned procedures worked for me so i've checked the documentation of anaconda and found something useful

conda install -c conda-forge/label/cf201901 jsonschema

conda install jupyter

jupyter notebook

this worked for me,thanks to anaconda documentation

Answer 6

If any of the above mentioned solution didn't work then try this in your anaconda prompt: First run conda update -n root conda so you have the latest conda version installed. Then run conda update --all This will update all packages in the current environment to the latest version. Even after installing jsonschema, your Jupyter Notebook might not run and give you the error:

Jupyter notebook format depends on the jsonschema package:

https://pypi.python.org/pypi/jsonschema

Please install it first Then I suggest you to run the given two commands. It will solve your issue as it solved mine.
