Hi Alenjandro,
More information here: https://www.python.org/dev/peps/pep-0405/#creating-virtual-environments What I am proposing is also a good idea for when python 3.6 is available in Yocto. With Python 3.5 one can create virtual environment by including python3-pyvenv OR python3-venv+python3-runpy. With Python 3.6 one will only be able to create virtual environments with python3-venv+python3-runpy. I hope I made it a bit clearer now. Thanks!

See the entire content of pyvenv: --------------------------------------------------- #! /usr/bin/python3.5 if __name__ == '__main__': import sys rc = 1 try: import venv venv.main() rc = 0 except Exception as e: print('Error: %s' % e, file=sys.stderr) sys.exit(rc) ---------------------------------------------------- As you can see, pyvenv depends on venv to run. Because it is confusing to have both pyvenv and venv; pyvenv has been deprecated in python 3.6. They should be two seperate packages not a single because they are different things. Read here for more information: https://docs.python.org/3/library/venv.html I do not understand what you mean by the cached files as I did not add it. After modifying the JSON I ran create_manifest3.py which added that, the rdepends content on venv was also added automatically after runny that script. My changes are only adding pyvenv and venv in the JSON. I will submit another patch which removes pyvenv in the python3 recipe.

The patch I am submitting is to add the venv module dependency to python3-pyvenv. The dependency has been added using the newly added venv package (python3-venv). The python3-venv package has been added for future proofing since pyvenv has been deprecated in Python 3.6 and creation of virtual environment is done using the venv module directly (i.e python3 -m venv my_venv).
