How to Install JupyterHub in a Conda Environment?

The easiest way to run an instance of JupyterHub is to install it in your personal default Conda environment. Here is how to do it.

1. Make sure that Conda is installed on the local computer.

fyicenter$ conda --version 
  conda 4.10.3

2. Activate your personal default Conda environment, which is also called "base".

fyicenter$ conda activate 

(base) fyicenter$

3. Install JupyterHub in the activated Conda environment.

(base) fyicenter$ conda install -c conda-forge jupyterhub
