I downloaded multiple modules (Discord API, cx_Freeze) (pip download, Windows 10) and now I wanted to use them. 
But when I want to import them, it says there isn’t any module. 
From my former Python using (before resetting computer) I‘ve added a pycache folder and it worked for one module. I‘m not able to reproduce it for other modules. What to do?

I‘ve only one Python version (3.6.5) on PC.
I‘ve checked the \site-packages folder and they‘re there.
If you are using python3 then try downloading the library using 

pip3 install libname

but if you are using python2 then install the library using 

pip2 install libname or just pip install libname

try with these command and reply
