'ERROR: Failed building wheel for pystan in Anaconda distribution. How to fix this error?
When trying to install Darts library its dependencies Pystan and Prophet were throwing errors:
- ERROR: Failed building wheel for pystan
- Building wheel for prophet (setup.py) error
Followed solution from here which redirected me to the pystan docs, https://pystan.readthedocs.io/en/latest/windows.html, which does not work.
How to solve this error? I would like to install Darts library successfully in Windows system Anaconda distribution.
Python 3.9.7

The link that I share in the question directed me to an incorrect path for troubleshooting pystan installation for Windows. The correct link is https://pystan2.readthedocs.io/en/latest/windows.html?msclkid=eb5dcb49ac2511ec829bf25d2eab26d6
When following all the steps from the above link I was successfully able to fix the issue. Also reiterating the steps I followed here.
- conda info
- conda update conda
- conda activate my_env (I already had an environment created from Anaconda UI with python 3.9.7)
- activate my_env
- conda install libpython m2w64-toolchain -c msys2
- conda install numpy cython matplotlib scipy pandas -c conda-forge
- pip install pystan
