Can't use Jupyter Notebook: jsonschema apparently missing

When using 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's what I do and the errors I get:

ben@ben-K60IJ:~/surveillance_sound_classifier/surveillance_sound_classifier$ source activate EECS352
discarding /home/ben/anaconda/bin from PATH
prepending /home/ben/anaconda/envs/EECS352/bin to PATH

Jupyter notebook format depends on the jsonschema package:

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

Please install it first.

Yes, I've done pip install jsonschema and conda install jsonschema AND pip install functools32 and conda install functools32 from within the EECS352 environment to no avail; I arrive at an almost identical error, except this time, functools32 is replaced with _version.

I've reinstalled Anaconda, updated all its packages, created a new environment in the same way I created this one, and still I get this error. I'm using Ubuntu 15.10 32-bit. I used to be able to use this environment with no problems until roughly a week ago.

If this is a duplicate, please point me to the original; however, I haven't yet found anything that seems really relevant. The only thing that might be relevant is that this error did pop up after I modified some .conf file because I was having issues updating my computer's software using sudo apt-get upgrade. I don't recall what I had done and to which file, but if it's likely the source of this issue, I can spend some time trying to track it down. Please let me know if I should spend my time to do this, and I will.

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

Re-install jsonschema solve the problem in my case:

$ pip uninstall jsonschema
...

$ pip install jsonschema
...

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.
