Prophet model in scikit-hts package is not working

I'm exploring hierarchal forecasting for time series in python and came across scikit-hts library. I installed the package using pip install scikit-hts. I followed the steps mentioned in this tutorial. I created the hierarchal tree and came to the modelling part. I want to predict bottom level forecast using Facebook prophet algorithm. I ran the following code

clf = hts.HTSRegressor(model='prophet', revision_method='AHP', n_jobs=0)
model = clf.fit(hierarchy_train, hierarchy)

This has thrown the warning message,

Fitting models:   0%|          | 0/46 [00:00<?, ?it/s]prophet model requires fbprophet to 
work. Exiting.Install it with: pip install scikit-hts[prophet]
Fitting models:   0%|          | 0/46 [00:00<?, ?it/s]

and this error message,

AttributeError: 'NoneType' object has no attribute 'fit'

I tried to install every additional package from here. But it is throwing the following error message for every package (here only shown for arima model)

zsh: no matches found: scikit-hts[arima]

Can someone please explain why it is happening? Is it because that the packages are discontinued or is there a issue in my installation process?

Edit:

1. I have updated my version of scikit-hts but still pip install scikit-hts[x] (where x=all/geo/arima/prophet) didn't work

2. I ran my code in the jupyter notebook. All models worked except for prophet. Here is the code.

   clf = hts.HTSRegressor(model='x', revision_method='OLS', n_jobs=20)
   model = clf.fit(hierarchy_train, hierarchy)
   

This code ran for x = auto_arima, holt_winters, sarimax but not for prophet I got the following error when I tried prophet

AttributeError: 'NoneType' object has no attribute 'fit'

Why is the model not running for prophet?

• I don't know if it is relevant or not but I have installed statsmodels packages for arima and other smoothening models. I have installed fb-prophet on my system but I didn't import in my notebook. I have only done import hts
