I'm not sure what you mean by pip and setuptools not being synchronised. Pip depends on setuptools and cannot be used without it. Both setuptools and pip are maintained under the PyPA. They are intended to work together. in fact if your setup.py uses distutils instead of setuptools then pip will "inject" setuptools into it to ensure that meets pip's needs. You will need to be more specific about which commands you are using and what it is that becomes unsynchronised. -- Oscar -- https://mail.python.org/mailman/listinfo/python-list
