It's not a huge obstacle, but it _is_ an obstacle. I'm not a Python programmer, but I can find my way around without much issue. Still, from where I'm sitting all that stuff about envs and the 2, 3 or 4 redundant, overriden, or deprecated mix of solutions sounds strange to me, I don't really want to buy into that just yet (I need Python like once per month, no more). For the casual programmer ("just want to change this line and run, please") it's just a block in the road that virtually all instructions you might see on any random README in Github might tell you to use "pip install..." but then you have to second guess if they mean "pip2" or "pip3", and whether they assume you'll be running with v2 or v3, maybe they tell you to run "pip install something" (which runs pip2), then in the script there is a Python 3 shebang... the installed dependency won't be found and now you have to understand all this mess if you want to continue. This is in Ubuntu, where the system's "python" is Python 2, and you need to explicitly add a "3" to all your commands if you want to run v3. I'm sure there are clever ways to solve the issue, but I bet they'll break some use case. I'd just rather none of this nonsense existed at all, then no funny workarounds would be needed. I wonder, how come other languages are able to slowly introduce some breaking changes over time (I'd swear Ruby was mentioned in some other HN thread about doing this) but not cause this kind of mess (as perceived from my humble external point of view)? |
