I have attached a snapshot of the error msg. I am using python 3.6.7. I tried 3.7 and 3.8. pystan install successfully. I tried different versions of pystan as others suggested. I have been trying for a few days, googled all the answers and tried most to no avail. Others suggested using Anaconda, but I am trying to use pip install. Does fbprophet require a specific version of python?
Here is what I tried and worked for me! At this point I started to learn that finding the right versions to download to ur system is like unlocking/cracking a safe and u have to find the right combination. So here is what worked for me. A lot suggested to use older versions of pystan and fbprophet. The ones that worked for me were:
pip install pystan==2.18.0.0
pip install fbprophet==0.6
Make sure to download Microsoft Visual C++ 14.0 or a newer version, otherwise, you will get an error during installing fbprophet:
"error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools."
Here is the link to download it: https://visualstudio.microsoft.com/visual-cpp-build-tools/ It will download Visual Studio Installer for u, which will pick the necessary tools for u (about 6 Gb). After that I was able to install fbprophet and import. There are other suggestions like using Anaconda in other posts, or using a different version of pystan and fbprophet. Good luck!
