Python : Failing to install scikit-learn (error code 1) on widows

I followed the instructions on the official sklearn website, and even if I fulfil the requirements I still cannot install sklearn. Here is the error message I get :

ERROR: Command errored out with exit status 1:

It seems like there is a problem with numpy but I already updated to the latest version. I'm on Windows 10, using Python 3.7, and numpy/scipy are up to date. Thanks in advance !
