I just had installed python in my laptop to work with some brazilian labor microdata then, following a tutorial on youtube I've installed some libs like pandas, matplotlib, numpy and jupyter notebook. And there is my problem.

The tutorial said to do pip install jupyter

and after, to run it jupyter notebook

but this happened at the command prompt

   jupyter : O termo 'jupyter' não é reconhecido como nome de cmdlet,
   função, arquivo de script ou programa operável. Verifique a grafia do
   nome ou, se um caminho tiver sido incluído, veja se o caminho está
   correto e tente novamente.
   No linha:1 caractere:1
     jupyter noteboook
     ~~~~~~~
     CategoryInfo          : ObjectNotFound: (jupyter:String) [], Com
   mandNotFoundException
     FullyQualifiedErrorId : CommandNotFoundException

well, the error message is in portuguese because I'm brazilian, but it means something like: "jupyter isn't recognize as a name of cmdlet, function, script file or program. Check the spelling of the name or, if there is a path that had to be included, see if it's correct and try again"

I've already tried to ins``tall jupyterlab, and running it as jupyterlab and had the same thing.

Don't know what to do and it's my very first time using Jupyter.

If you have installed virtual environment make sure you are in that directory before you open jupyter notebook.

using pip freeze you can check which package is installed.

If you have not installed virtual environment I strongly suggest to do so its quite easy.

command - python -m venv

MY jupyter notebook not work after installing and calling in CMD.

then i only use "pip install simplejson" in command prompt (cmd) . Then i write "jupyter notebook" and it work!

someone uses "pip uninstall simplejson" before "pip install simplejson".
