Setting up a new machine for rails.

I am wondering if there is an quick and easy way to set up a new machine which duplicates the rails env of another machine. I have in the course of last several months installed many gems and it would be great if I didn't have to make a list and re-install all the gems.

On a related matter... Is there a way to tie this into migrations? I mean if I need a new gem is there any way I can get capistrano to migrate my gems as well as my database schema changes?

Thanks.

#!/bin/sh

for x in `gem list --local | grep '(' | sort | awk 'BEGIN { FS = " " } { print $1 }'`; do   echo "gem install $x" done

Wow. Thanks. I would have to pipe this to a file and remove any windows specific gems but that's great.

wouldnt you want something like:

echo "gem install $x -y"

to install all dependencies? I think it would also get stuck on the multiple version menu that always seems to come up, wouldn't it?

It produces a list of _all_ the gems installed, what dependencies?

You would need to run it by hand, yes.

I’ve had success eliminating the prompt by passing the version number, like this:

gem install -y mongrel --version 0.3.13.4
