python - Installing PySCIPOpt via pip doesn't work

Question

I tried installing PySCIPOpt with pip by doing "pip install pyscipopt" using this guideline: https://github.com/scipopt/PySCIPOpt/blob/master/INSTALL.md and looking at diffrent questions with the same problem. I'm running Python 3.8 with Anaconda on a 64-bit Windows 10 machine.

I have sucessfully installed th SCIP Optimization Suite. I do have the folders lib and include and in the folder include there is a file scipscip.h. And finally I installed Microsoft Visual C++ 14.0.

I run the following commands in the Anaconda Prompt:

set SCIPOPTDIR=C:Program FilesSCIPOptSuite 7.0.0
pip install pyscipopt

I've also tried diffrent variations like for example:

set SCIPOPTDIR="C:Program FilesSCIPOptSuite 7.0.0"
set PATH=%PATH%;%SCIPOPTDIR%in
python -m pip install pyscipopt

However I keep getting the following error message.What am I doing wrong?
