Please carefully go through the error message before opening an issue here.

It already said in the error message:

Unable to find either executable 'empy' or Python module 'em'... try installing the package 'python3-empy'

So just install the package, and build it again.

Thank you for your prompt response. I have already installed it. Do I just need to follow the install.md?

Yes, please just follow the instructions.
