I have a bunch of virtual environments which need replicating from one machine to another. In the past rsync was OK, but now with slightly different environments I have been using pip freeze to get a list of the installed requirements and pip install to carry out changes to the remote environment. Is there a way to resolve issues where pip reports a different package to the one installed eg the original requirements say git+http://github.com/django-cumulus/django-cumulus.git@master#egg=django-cumulu... but pip freeze will only say django-cumulus===1.0.19-22-g506121d ie we lost the actual installation notation. Given that the git location is actually unstable ie the revision can change it seems quite hard to get reproducibility in an automatic fashion. g506121d is derived from the repo hash (https://github.com/django-cumulus/django-cumulus/commit/506121d8669e1cce8843...), but I see no way to guess that from the version string unless there some standard decoding I can do of the revision. -- Robin Becker
