ERROR: Failed building wheel for OMSimulator (when installing using proxy network on Linux)

Question

I am using a Linux Virtual Machine on the company network, which requires a proxy setting. I am trying to install OMSimulator through pip, using the following command. pip3 --proxy http://proxy.company.com:<port> install OMSimulator --use-pep517 (I have hidden the proxy address)

Full Error Message:

  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for OMSimulator

Based on the error message it looks like a difficulty in connecting to build.openmodelica.org through the proxy server. Is there anything I am missing?

Note: I am able to install other packages like numpy, pandas etc with the proxy. The error is only for OMSimulator.
