Failed to locate Metis

[VistaLee]

Hi.
I installed metis with 'pip install metis' and an error occurred: 'RuntimeError: Could not locate METIS dll. Please set the METIS_DLL environment variable to its full path.' In the linkhttps://metis.readthedocs.io/en/latest/_modules/metis.html I knew that I needed to download this: http://glaros.dtc.umn.edu/gkhome/views/metis
but still I failed to build the source code of metis.

Would you please give me some advise on solving this problem? Thank you in advance!
