Ruby virtual development environment

I mainly develop ruby ​​on rails on my car, but from time to time I end up using other laptops to develop RoR. It would be nice if there was something (perhaps a shell?) That basically brought all the gems installed on my machine to another machine without leaving any traces. It is basically a really lightweight virtual machine without an OS.

If that matters, I use mac. Ideally, I would like to keep this virtual environment in my Dropbox, and basically, when I use some other machine, I just get it from my Dropbox and start coding and don't have to worry about setting up the environment.

As with Jacob's answer, I would recommend using RVM , but I will expand it. Here are some ideas for brainstorming:

RVM saves its sandbox in your home directory at ~/.rvm. All instances of Ruby, as well as gems associated with them, will be stored there. This is a simple addition to the file ~/.bashrcon your Mac to initialize RVM, so it is known by the shell when you log in to your account. It is also simple rm -rf ~/.rvmfrom the command line to remove the RVM sandbox from the account, after which the line from is deleted ~/.bashrc.

So basically, by setting up RVM correctly and installing your Ruby installation on one machine, you get 90% of how it is available for several machines.
