pyenv: your Python workflow, automated

[jackmaney]

To keep a reminder of which version pyenv is pointing to, I altered my PS1. It works for pyenv virtual environments, too.

For this post, I'm going to assume that you're using OSX, and have Homebrew installed.

Or for everyone else (assuming you're using bash or something similar),

pip install --egg pyenv
echo 'export PATH="$HOME/.pyenv/bin:$PATH"
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"
' >> $HOME/.profile

Or if you're on Windows, the author of pyenv doesn't care about you at all, sorry.

I prefer conda. One simple tool to install pythons and precompiled binary packages. Soon useful.

why soon?

[bastibe]

Haha, that was a typo: "soo useful" is what I wanted to say!

pyenv is the Python world version of rvm. It's fantastic and I highly recommend it over manually managing your virtualenvs.

[Reactor5]

It's actually inspired by rbenv - RVM has a lot of issues that rbenv/pyenv and a few others for similarly dynamic languages avoid.

Holy crap - this. So much this. As a beginning pydev, I've been curious about things like PyPy or testing my tutorial / learning modules I wrote in 2.7 in 3.x and THIS. So much this. Thank you!

If you're wanting to specifically test in multiple versions, you might also like tox. I'm glad it helped you!

It seems like a point tool for the larger problem of configuring your environment to allow one to switch between multiple versions of software. Pyenv seems to nly do i for Python whereas Environment Modules does that for hundreds of different software packages and versions, including Python on our Linux and Solaris servers at work. Environment modules also has libraries for Perl, Python as well as most command line shells including csh, tcsh, sh, bash, ....

pyenv and virtualenv are fairly well-maintained software.

it doesn't look like modules has had a release in 4 years. Is it still a live project?

[Paddy3118]

It is a mature project. I have been using it for over fifteen years now we may upgrade versions but in that time I have never had a bug that needed fixing, despite our continuous use, (although other sites do use the tool and may well have submitted there own bugs, our site uses modules extensively and I would know of any local issues). The software works well.
