Installation as a requirement via pip fails - incompatible version of bw2io #16

Closed aleksandra-kim closed 6 years ago

aleksandra-kim commented 6 years ago

Original report by James Joyce (Bitbucket: pjamesjoyce, GitHub: pjamesjoyce).

The version of bw2io on PyPi (0.5.12) is different from the version on anaconda cloud (0.6.RC5).

v0.5.12 tries to import database_parameters from bw2data, which it can't do, so loading brightway2 installed via pip throws an import error.

I know the recommended installation is via conda, but I'm writing an extension for lcopt (for parsing hand drawn flow diagrams into lcopt/brightway models) called lcopt-cv and one of the computer vision dependencies is only avaliable on PyPi (as a wheel so it can't be conda skeletoned). I was trying to include brightway in the setup.py install_requires list so it could have a one-step install when I noticed the problem.

Low priority - it's an edge case, and installing most things via conda and then installing something extra via pip isn't a big deal - but figured you might want to know.

RC5 is still a "release candidate", so pip will only install it if you pass "--pre", see https://pip.pypa.io/en/stable/reference/pip_install/#pre-release-versions.

RC5 is on pypi: https://pypi.org/project/bw2io/0.6rc5/
