Missing requirements.txt in published PyPi package

[aciceri]

I'm not confident saying it but I believe it's supposed to be part of the PyPI package tarball.

Having the requirements.txt file published on the PyPi tarball would also avoid this workaround in the nixpkgs package definition.

I can confidently say that the sdist on PyPi is broken, because there is a requirement in the setuptools install routine.

tuya-device-sharing-sdk/setup.py

Lines 6 to 8 in 9bfb454

	def requirements():
	with open("requirements.txt") as fileobj:
	return [line.strip() for line in fileobj]
