A previous python project I worked on had multiple independently developed services, sometimes with conflicting requirements. Production often separated these, but keeping staging and local development environments happy was a constant struggle. I also like to make sure the devs are working with an environment that translates directly to production (docker makes this much easier now). I really don't enjoy sorting out a blob of code that only works with your specific local configuration: - ok requires opencv (or other complicated dependency). No problem, that's already in production. - Oh it only builds against the 2.4.7.1 version you have on your machine. - Hmm, 2.4.7.1 has a bug when used with common_lib version X on distro Y - etc.
