Error: hyperkit: no bottle available!

While installing hyperkit on mac using brew I am getting this error.

Error: hyperkit: no bottle available!
You can try to install from source with:
  brew install --build-from-source hyperkit
Please note building from source is unsupported. You will encounter build
failures with some formulae. If you experience any issues please create pull
requests instead of asking for help on Homebrew's GitHub, Twitter or any other
official channels

So I ran brew install --build-from-source hyperkit and got this error,

READ THIS: https://docs.brew.sh/Troubleshooting

Any idea on why this is happening and how to solve this?

Start by reproducing the Homebrew source build and inspect src/lib/vmm/intel/vmx_msr.c and the related src/lib/vmm/intel/vmx sources around the hv_vcpuid_t errors. Compare the failing build context with the HyperKit source and macOS environment; done means the reported source installation builds successfully without these compiler errors.
