Kenneth Reitz - Pipenv: The Future of Python Dependency Management - PyCon 2018

Speaker: Kenneth Reitz
This talk is about the history of Python packaging, the tools that have been historically available for application deployment, the problems/constraints presented by them, and presents a holistic solution to many of these problems: Pipenv.
A live demo of the tool will be presented, as well as a Q&A session.
Slides can be found at: speakerdeck.com/pycon2018 and github.com/PyCon/2018-slides

I started using Pipenv couple of weeks ago. Now I don't know how I did without it.

[@Mezklador]

Coming from PHP and Javascript, I always wonder why there's not the same features with Python Packages Manager. Now, it"s done, it's easy, it's more efficient. Thanks Kenneth and keep going with great tools like Requests and Records!

[@gharabed]

Great presentation...sorry I missed it while I was at PyCon. By the way, demo starts at 20:20

[@flevin58]

Very inspiring and thank you for pointing me out on the right direction: I just joined the Python Software Foundation

[@rmarianoanaya]

Awesome explanation! Very nice talk.

[@chesterholt5551]

wonderful presentation. thanks

[@Mike.e]

Great talk, thank you!

[@iivarimokelainen]

@Kenneth Reitz, what do you think of sdispater/poetry?

[@nikjs]

How do I make pipenv make a different python version virtual environment than the latest one on my system? I want to make a python 2.7 virtual environment

[@gusutabopb]

Thanks for the talk. What do you use to display the execution time of the last command and current datetime in every line of the shell?

[@ikickss]

It looks like powerline.

[@zhuyixue4979]

how to make PS1 timing like that in the demo, esp. to the right?

[@Repeatunt1l]

pyenv + pyenv virtualenv is still better choice for me. It's quicker and more simple.

[@rhettsmedia]

Just tried this package on my set up and it just blows up it will not run not sure it’s maybe too fragile still

[@bartek8981]

What's the terminal's font name?

[@pleggli]

I very much like the way Go is heading with minimal version selection and no lock file.. Sadly it would be harder to fit that in into the existing python pip MOs so pipenv probably takes the best route possible considering external factors...

[@senpos]

Wow, installing requests in demo worked so fast! Unfortunately, it is not that smooth on my Windows machine for some reason, especially the process of locking dependencies to the file.

[@Alphare33]

Keep in mind that pipenv is updated probably about every 32 milliseconds, and they improve performance all the time.

[@flaviocpontes]

You should try a unix like system. Since I migrated from windows to linux, i've been a lot more productive. And it's not so difficult.

[@veganath]

29:13 had to do a double take was that *Elon Musk* asking a question...lol

[@ejay4032]

The ever brilliant Kenneth Reitz

[@pha1994]

Ehigie Aito Also the ever arrogant on an open source forum.

[@Sousleek]

when it installs it automatically install pyenv?

[@chrish42]

No, it won't. But if pyenv is already installed, it will use it.

[@williantuness]

Are you in doubt if you should use it or not? See 19:19

[@xxyyy1329]

only the locking is looooooooooooooooon time consuming....

[@Kiaulen]

What font is that in his terminal? It looks a little like Fira Code, but the @ glyph is different

[@KennethReitz42]

Operator Mono!

[@Kiaulen]

That explains why it didn't show up in any lists. $199 is pretty expensive for a font, even if I would be looking at it every day. Was it worth the purchase? Also, thank you so much for requests. It's the best HTTP lib in any language I know of.

[@KennethReitz42]

I got it for free, thankfully, but I'd say it's worth the investment if you work in monospaced fonts every day.

[@pleggli]

Pragmata Pro is also a good choice of programming font if you are going to pay for one..

[@stasbovanenko]

Google Hackfont. These days you can build Fira with any set of glyph. Also modern terminals allow you to set separate font for glyph, check out Kitty or iTerm2 if you are on Mac.

[@victornoagbodji]

powerful stuff.

[@DeepSukhwani]

Hey Kenneth, super amazing. Thanks so much - One question for you - Whats the shell you use? Its so damn productive. and what are those numbers in milliseconds on the right end of the shell environment? Please do educate us.

[@Nophk3]

the shell is Fish !

[@chozairitu6975]

wow

[@larseneivind]

What terminal is that? great talk btw :D

[@iqao]

I think that's fish running in iTerm2. Judging from him using activate.fish

[@Karebear9001]

looks like fish

[@Kiaulen]

Yep, fish using the bobthefish theme

[@larseneivind]

Thanks for the replies, I will update my iTerm2 to use this :D

[@victornoagbodji]

i use fish with out of the box mac terminal. no need for iTerm2

[@funkindy]

The future: 30 minutes pipenv install

[@josephs3973]

TOML. The markup language nobody asked for, nobody needs, but now we're gonna be stuck with it because the cool kids are using it. God damn it.

[@user-ug1kh2ne2f]

speak for yourself but not for anybody

[@nobytes2]

Dunno why is called toml, but looks just like ini files lol

[@stasbovanenko]

I also failed to understand how we managed to came back to .ini :/ I really wanna shout '"AML 'till the day I die", but it wouldn't be fair, since I'm using Dynaconf for configs and have absolute freedom in this dimension.
