rvm, rails and sqlite

i need to use old version of ruby (1.8.7) and older version of rails
(2.1.0) so i decided to use rvm. however since i'm somewhat new to ruby
and rails i'm having issues. i created a gemset with rvm for my project,
installed rails 2.1.0 into it. after that i created a project and a
scaffolding for it. however i bumped onto an issue with sqlite3 (or
sqlite3-ruby). it seems to me that sqlite3-ruby gem is not installed. i
tried installing it using

gem install sqlite3-rub

but here is what i'm getting

Building native extensions. This could take a while...

i tried searching online but the solutions either don't fit my needs or
they don't work.

any help would be greatly appreciated

First question: why do you need to do that?

so i decided to use rvm.

Good choice.

however since i'm somewhat new to ruby
and rails i'm having issues. i created a gemset with rvm for my project,
installed rails 2.1.0 into it. after that i created a project and a
scaffolding for it. however i bumped onto an issue with sqlite3 (or
sqlite3-ruby). it seems to me that sqlite3-ruby gem is not installed.

Why does it seem that way? What is your basis for believing this?

i
tried installing it using

gem install sqlite3-rub

but here is what i'm getting

And did you follow these instructions?

Best,

On which Operating System are you working? Useful to mention
in such cases of OS dependent installation problems.

In case it would be a Debian derived GNU/Linux box (e.g. Ubuntu),
my standard approach is this:
* almost always, it is the xxxx-dev package you are missing
* find the context with apt-cache search 'xxxx*' | grep dev
* then check if installed (with dpkg -l 'xxxx*')
* then check which files are in there (with dpkg -L <package name>)

So I found quickly that the sqlite3.h file (that you seem to
be missing), is in the package libsqlite3-dev (as expected actually).

The log of that is:

peter thanks for the help. it turns out i needed to run

rvm notes

and there was a list of packages i need to install to successfully work
with rvm

after that i ran

sudo apt-get <list-of-packages> and everything started working

your solution was similar to what i have done

Hello Rail!

I would use this method:
- check RVM, set all thing you need, see also this part
http://rvm.beginrescueend.com/gemsets/basics/
- is sqlite installed? is it running?
- check if needed Ruby version installed and if you can switch,
- gem version you need,
- particular gem you need - this case sqlite3-ruby,
- rails version you need,
- finally .yaml

Important: If you're on Unix, do NOT use 'sudo' when istalling a gem!
(And always pay attention which gem and which Rails do you intall with
a Ruby version.)

If you have further problems, it is almost surely because of old gem.
Others wrote on mailing list before that if nothing else worked, they
uninstalled then reinstalled their gem, after that it worked fine.
Please check answers before in this mailing lists, I met with these
questions several times. (Or you can write me in private also, I had
so long struggle with this.)

If you have still problem can you list me here your:
OS, rvm -v, ruby -v, rvm list, gem -v, gem list, rvm gemset list,
please. Good luck,
Zoltan

zoltan,

thanks for help. i solved the problem by doing the following:

rvm notes

returns a list of modules that needed to be installed on linux. after
that i

gem install sqlite3-ruby

and everything worked fine.
