Cannot Run Jupyter Notebook on Terminal

for my homework we need to use jupyter notebook to run an .ipynb file. I use Mac and I used pip install jupyter to install it using terminal, which was successful. However when I tried to open it using the commandjupter notebook I get this error. Any ideas? Thanks.

The correct answer is actually what came out in the comments, I'll report it here for future viewers:

pip install jupyter
pip install notebook
jupyter-notebook your-file.ipynb

See you!
