Error - "sudo ruby setup.rb"

[rjafrate]

Simply Rails pg 35, instructs to execute $sudo ruby setup.rb but when I do so I get the following error message:

rick@odin:/usr/lib/ruby/1.8/rubygems$ sudo ruby setup.rb
ruby: No such file or directory -- setup.rb (LoadError)

Previously the book instructs to CD to the rubygems directory. I am running Kubuntu 9.10 and I found the rubygems directory at /usr/lib/ruby/1.8/rubygems. Here is a listing of that directory.

I am having problems with this part and also with installing the "SQLite Database Interface for Ruby" later on.

Can anyone help with these issues or in getting setup on Kubuntu 9.10? Thanks!

This page has a location you can download setup.rb from:

Thanks! When I follow the instructions from the book I get the following results.

Now, I am still having a problem installing the SQLite ruby interface. Here is a dump of my terminal showing the versions of everything else that installed okand the attempt to install squlite3-ruby.

Any iodeas of wehat I am doing wrong. Btw, this is on AMD 64-bit Kubuntu 9.10. Thanks in advance for any help you can give.

Ok, tried reinstalling ruby from kpackagekit GUI. Documentation is is but still have a problem installing sqlite3-ruby through gem.

rick@odin:/var/lib/gems/1.8/gems$ sudo gem install sqlite3-ruby

From the Kubuntu GUI I was able to install yhe following packages

libdataobjects-sqlite3-ruby1.8 - 0.2.5-2 (amd64)
libsqlite3-ruby1.8 - 1.2.4--2 (amd64)
libdb-sqlite3-ruby - 1.2.4-2 (all)
libdbd-sqlite3-runy1.8 - 1.2.4-3 (all)
libsqlite3-ruby - 1.2.4-2 (all)

How can I test to see if I have access to SQLite database through ruby? Or else how can I get gem to make the installation?

[Louis Simoneau]

to test if you have sqlite3 available to ruby, just launch an irb console and type:

require 'sqlite3'

If that returns true you're all good. Otherwise, to be able to install the gem, you need to have the package ruby1.8-dev installed, that's the package that contains mkmf.rb, so:

sudo apt-get install ruby1.8-dev
sudo gem install sqlite3-ruby

Hope that helps
