Hello Boys and Girls,

I don't know where this item belong. I am posting it on both, Ruby and Rails
forums.

# ruby -v
ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-linux]

# rails -v
Rails 3.1.0

Red Hat Enterprise Linux Workstation release 6.0 (Santiago) (64bit)

I just installed Rails 3.1.0 as described on:
http://guides.rubyonrails.org/getting_started.html
One of the step while trying to create my first project was to: Creating the
Database

$rake db:create
(in /opt/rails_3.1.0/Code/Ruby/blog)
Could not find gem 'sqlite3 (>= 0)' in any of the gem sources listed in your
Gemfile.

So, I assumed that sqlite3 was not installed.
I proceeded to make several attempts to get sqlite3 installed but got
errors. I also tried installing sqlite3-devel as suggested below by the
error messages, but got errors.

# gem install sqlite3
Building native extensions.  This could take a while...
/usr/local/lib/ruby/site_ruby/1.9.1/rubygems/ext/builder.rb:48: warning:

This is telling you don't have the development files for sqlite installed.
sqlite3.h is missing. Try 'port install sqlite3 +universal'
or 'yum install sqlite3-devel' and check your shared library search path

You may have tried them, but your original post does not say that you
followed the instructions
"Try 'port install sqlite3 +universal'
or 'yum install sqlite3-devel' and check your shared library search path
(the
location where your sqlite3 shared library is located)."

Or what the result was

Anyway, this is what I got:

yum install sqlite3-devel

As I said before, I am running Redhat 6.1 64bit.

That or one of the others may be helpful

Colin, the link you gave me helped install sqlite3. That's fine.

However, it looks like Rails is still looking for more dependencies, which I
already installed, except that I hit one which I can't see how to address
it.
The execjs wants a javascript runtime. I installed at least three suggested
ones:

ExecJS supports these runtimes:

therubyracer - Google V8 embedded within Ruby
therubyrhino - Mozilla Rhino embedded within JRuby
Johnson - Mozilla SpiderMonkey embedded within Ruby
Mustang - Mustang V8 embedded within Ruby
Node.js

and I am still having the same error messages, which I am posting below.

I am truly sorry to bother you but I hit a wall. Also, I am not sure why
Rails does not load everything it needs. It already loads a large number of
pre-reqs.

Thank you

Are those on your path? I mean, the executable for those runtimes.
Can you just run
$ node
for example?

Leonardo,

Yes, the executable are on my path. However, you suggested to type *node*,
which was the only one I had not installed.
I downloaded and built *node* and now I am past that issue.

However, NOW I have other issues. This is like pulling teeth. If I did not
want to learn Rails so badly, I would drop this altogether.

This is what I am getting now:
