  • I highly suggest you to use python through anaconda environment (download it from here https://www.anaconda.com/products/individual) and then open the anaconda prompt and run conda install -c conda-forge fbprophet in a super easy way. I also had problem with installing fbprophet. Regarding pystan, I never tried to install. – Tom Dec 30 '20 at 19:10
  • @Tom, I tried as you say, but got other errors. Pasting below – Krishna75 Dec 30 '20 at 19:15
  • (base) C:\Users\srikrishnamupalaneni>conda install -c conda-forge fbprophet Collecting package metadata (current_repodata.json): failed CondaHTTPError: HTTP 000 CONNECTION FAILED for url Elapsed: - An HTTP error occurred when trying to retrieve this URL. HTTP errors are often intermittent, and a simple retry will get you on your way. 'https://conda.anaconda.org/conda-forge/win-64' (base) C:\Users\srikrishnamupalaneni> – Krishna75 Dec 30 '20 at 19:15
  • I don't know where that error could be coming from . Did you try to install anaconda again? Try to create a new anaconda environment and install with conda install -c conda-forge fbprophet ? Idk ,I've installed that way in many computers with windows and never failed hahah. – Tom Dec 30 '20 at 19:32
  • This appears to be an issue with SSL rather than a problem specific to this package. See, e.g., https://stackoverflow.com/questions/42509902/ssl-certificate-verify-failed-using-pip-to-install-packages for solutions. – Eric Truett Dec 30 '20 at 19:33

Thank you All for responding, I got the problem solved. Solution - There is a Firewall installed on my laptop by my company. It is blocking me from installing some packages.
