For Juptyer, a simple pip package needs to be installed. Be careful, as there are multiple Python and pip versions—based on the pip version linked to a Python version, Jupyter would be installed accordingly for that version.
Prerequisite: Python and pip should be installed.
The following is the command to install Jupyter:
pip install jupyter
Jupyter can be installed using the Anaconda/Conda distribution as well, refer Jupyter Documentation: Installing Jupyter Using Anaconda and Conda, retrieved from https://jupyter.readthedocs.io/en/latest/install.html#installing-jupyter-using-anaconda-and-conda.
