Answer 1

/fbprophet/models.py", line 209, in build_model import pystan ModuleNotFoundError: No module named 'pystan' ---------------------------------------- ERROR: Command errored out with exit status 1
This is your error message. Have you installed pystan ?
If you have and are still getting this error then try uninstalling pystan and install a older version.
I had the same issue and the below worked for me:
Step 1: Uninstall pystan
pip uninstall pystan
Step 2: Install pystan version ~2.14
pip install pystan~=2.14
**Step 3: Try installing fbprophet again **
pip install fbprophet
Reference.

Answer 2

After making sure you have the right python version.
Update apt and install following libraries.
sudo apt update
sudo apt install python3-dev python3-pip python3-venv
use python3 -m pip to install pystan and prophet
python3 -m pip pystan
python3 -m pip prophet
