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-cumulus
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/506121d8669e1cce8843d9f76f2767324f8b1e78),
but I see no way to guess that from the version string unless there some
standard decoding I can do of the revision.
