jupyter not working from terminal [mac m1] zsh

Question

I have installed Miniforge on my macbook air m1, and then did the following steps to successfully install jupyter and launch it:

chmod +x ~/Downloads/Miniforge3-MacOSX-arm64.sh
sh ~/Downloads/Miniforge3-MacOSX-arm64.sh
source ~/miniforge3/bin/activate

mkdir data-science
cd data-science

conda create --prefix ./env python=3.8
conda activate ./env

conda install -y jupyter 
conda install pandas numpy matplotlib scikit-learn tqdm 

Then: I launched Jupyter this way:

jupyter notebook

Everything worked fine. But when I exited the terminal and opened again and typed:

jupyter notebook

I got this error: zsh: command not found: jupyter

What is the problem?

I know that this is a path problem, but even when I go to env environment, and I run jupyter notebook I get the same command error.

Answer 1

Im not sure but I think you need to reactivate the environment each time you restart the terminal sesion.

conda activate ./env

then run your code
