Coming off from my last post about updating pip inside a virtualenv, I have, finally, realized what I’ve been doing wrong all this time: I use this nifty script called virtualenv burrito to get a virtualenv + virtualenvwrapper set-up.
I’ve been writing an install script for a new project I am working on. Being at such an early phase, the script is scrappy and will only probably work for machines configured exactly as mine. Not that I make a lot of customizations, but still it relies on the existence of virtualenvwrapper too much.
The thing is I could never get my install script to run properly since pip is broken in my virtualenvs. So just yesterday, I finally decided to devote some time to digging into why precisely this is happening.
Long story short, after a few hours digging around the Vogon poetry of bash scripting, I realized that I can’t find separate virtualenv and virtualenvwrapper installs in my system…because I used virtualenv burrito to install them.
So I deleted the .venvburrito directory in my home and rerun virtualenv burrito. And…tadddaaaahhh!

What this does not address, however, are my old virtualenvs which are stuck on an outdated pip. But I guess it should be trivial to just delete those virtualenvs and create a new one, this time with an updated pip.
There’s this thing in life, where you have assumptions you neglect to state because you thought (assume) them to be inconsequential, then they turn out to be of great importance. This is all the more true when you work with computers.
