Error installing FBPROPHET in my windows machine

Question

I am getting the below mentioned error while installing fbprophet in the Windows environment, and, also setup.py is being triggered as part of installation as the installation using wheel file fails.

Installation of fbprophet library: Using legacy 'setup.py install' for fbprophet, since package 'wheel' is not installed

(new_venv) C:\Users\anno_user\Downloads\DocumentDB-Quickstart-Python>pip install fbprophet
Collecting fbprophet
  Using cached fbprophet-0.7.1.tar.gz (64 kB)
  Preparing metadata (setup.py) ... done

Using legacy 'setup.py install' for fbprophet, since package 'wheel' is not installed.
Installing collected packages: fbprophet
  Running setup.py install for fbprophet ... error
  error: subprocess-exited-with-error

And we are getting this following error when setup.py is installing the package:

  × Running setup.py install for fbprophet did not run successfully.

  note: This error originates from a subprocess, and is likely not a problem with pip.
error: legacy-install-failure

× Encountered error while trying to install package.
╰─> fbprophet

note: This is an issue with the package mentioned above, not pip.
hint: See above for output from the failure.

Please kindly suggest if there is any workaround (or) fix for the issue I am facing. Also, mention the python version along with the dependencies version for installing fbprophet from pypi.org.

Answer 1

These commands no longer work.

a) "fbprophet" is now "prophet"

b) need legacy versions of pystan and cmdstanpy

pystan=2.19.1.1 cmdstanpy=0.9.5

My Windows OS fails to install pystan=2.19.1.1 so I have given up. But "pip install prophet" works on both Google Collab and GCP Workbench.
