CompileError : command 'C:\\MinGW\\bin\\gcc.exe' failed with exit status 1 while installing pystan

Question

i'm trying to get pystan to work on Windows 10 in order to use the fbprophet package for time series. I have already installed MinGW, added its directories to my PATH environment variable and tried this piece of code to verify everything is working fine:

gcc -dumpversion
ld -v
dllwrap -version

which yields these results:

C:\WINDOWS\system32>gcc -dumpversion
6.3.0

C:\WINDOWS\system32>ld -v
GNU ld (GNU Binutils) 2.28

C:\WINDOWS\system32>dllwrap -version
GNU dllwrap (GNU Binutils) 2.28

everything iw working fine to this point.

The problems comes when once in python, i try to execute the following code:

import pystan
model_code = 'parameters {real y;} model {y ~ normal(0,1);}'
model = pystan.StanModel(model_code=model_code)
y = model.sampling(n_jobs > 1).extract()['y']
y.mean()  # with luck the result will be near 0

for which i'm getting this output:

import pystan
model_code = 'parameters {real y;} model {y ~ normal(0,1);}'
model = pystan.StanModel(model_code=model_code)
y = model.sampling(n_jobs > 1).extract()['y']
y.mean()  # with luck the result will be near 0

CompileError: command 'C:\\MinGW\\bin\\gcc.exe' failed with exit status 1

I have searched on the website prior to posting this question, as well as in other websites, but nothing seems to work for me. I'd appreciate any help.

Thanks in advance
