Cannot install fbprophet

Question

c:\users\gmmke\appdata\local\programs\python\python310\lib\site-packages (23.2.1)

when I install 'fbphrophet' using pip I get the following error;

error: subprocess-exited-with-error
  
  python setup.py egg_info did not run successfully.
  exit code: 1
  
  [6 lines of output]
  Traceback (most recent call last):
    File "<string>", line 2, in <module>
    File "<pip-setuptools-caller>", line 34, in <module>

      from Cython.Build.Inline import _get_build_extension
  ModuleNotFoundError: No module named 'Cython'

  note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed

Encountered error while generating package metadata.

See above for output.

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

I have the latest pip version

C:\Users\gmmke\Desktop\Stocks Predictions>python -m pip install --upgrade pip
Requirement already satisfied:pip in c:\users\gmmke\appdata\local\programs\python\python310\lib\site-packages (23.2.1)

Cython is aready installed

I followed this article Prophet / fbprophet package in Python.
And did;

conda install libpython m2w64-toolchain -c msys2

and also;

conda install -c conda-forge fbprophet

But still did not work.
Same error as above for pip install pystan

make sure to double check where Conda is installed. Check that you are in the correct conda as well as pip environment for installing the package
