First, activate your python virtual environment and follow these steps:
 
             $ python3 -m pip install sage_conf
             $ ls $(sage-config SAGE_SPKG_WHEELS)
             $ python3 -m pip install $(sage-config SAGE_SPKG_WHEELS)/*.whl 
             $ python3 -m pip install sagemath-standard
 
-You need to install the `sage_conf`, a wheelhouse of various python packages. You can list the wheels using `ls $(sage-config SAGE_SPKG_WHEELS)`. After manual installation of these wheels you can install the sage library, `sagemath-standard`.
