Unsupported compiler -- at least C++11 support is needed! about ecsim HOT 2 OPEN

Hey, if all you want is to use ecsim from Python, you can install it using pip: pip install pyecsim

from ecsim.

Hi pip install did not work, I get error:
ERROR: Could not find a version that satisfies the requirement pyecsim (from versions: none)
ERROR: No matching distribution found for pyecsim

I did manage to install your "PyESP". I am very excited to try it. However, the manual in the link "http://lem.ch.unito.it/chemistry/esp_manual.html" cannot be reached. If it can be found in another site I would appreciate if you point me in that direction.
Are the functions in ESCIM and PyESP similar? Can I learn PyESC from the examples provided for both programs?
Thank you very much!
