source install bug (on MacOS arm64) - No such file or directory: 'src/esig/VERSION'

I'm getting the error for pip install esig (on a platform which doesn't have wheels)

Thanks for raising an issue. What platform are you building esig for? This issue hopefully is easily fixed, but building esig is notoriously difficult because of its dependencies.

MacOs on Apple Silicon.

I assumed it's this commit: https://github.com/datasig-ac-uk/esig/commit/0fae49ebcab27026c1b86648b1cfbad016412a8e

Because previous versions don't have this specific problem.

As for difficulty of building esig, yes I wasn't able to build or install it on my machine, so I expect that even after fixing this issue I'll not be able to build it.

Ok this is caused by a problem with the MANIFEST.in file not having been updated for the newer version of esig. I've fixed this in #128 along with another problem.
