It looks like you are trying to install "classic vpython" and not the newer vpython. Is this what you are intending to do?
The latest version of VPython is vpython 7 and instructions for installing it are found at http://vpython.org/ .
You can install the new vpython with either conda or pip.
Using conda you intall vpython 7 with the following command.
conda install -c vpython vpython
Using pip you can install vpython 7 with this command.
pip install vpython
The "classic vpython" is no longer supported and is not undergoing any further development. The new VPython 7 is what is currently supported. There are some changes between "classic vpython" and the new vpython. See the documentation for the code syntax for VPython 7 and here is a description of the evolution of vpython.
