How to use two versions of Vagrant on a Mac

Vagrant doesn't make it easy to manage multiple versions of it. I was lucky enough to ended up working on a project whose vagrant up only works with the legacy Vagrant 1.4 and another one that only works with newer versions. I'll explain here how I managed to keep both. In this case I'll install Vagrant 1.4.3 and 1.7.4 (the newest as of now), but in principle it should work with other versions as well.

1. Install VirtualBox 4.3 and Vagrant 1.4.3

Vagrant 1.4.3 doesn't work with newer versions of VirtualBox (>4.3). During this experiment I messed up all my installations several times, so I'm installing everything from scratch (just go to the download page, download the dmg and run the pkg installer normally).

2. Hack the Vagrant 1.4.3 installation

The final result: require() any module on npm in your browser console with browserify

This article is written to explain how the above gif works in the chrome (and other) browser consoles. A quick disclaimer: this whole thing is a huge hack, it shouldn't be used for anything seriously, and there are probably much better ways of accomplishing the same.

Update: There are much better ways of accomplishing the same, and the script has been updated to use a much simpler method pulling directly from browserify-cdn. See this thread for details: mathisonian/requirify#5
