Installing Ruby & Rails on Ubuntu 12

Ruby
1

I have been trying to install Ruby on Rails and get an environment
working for about 10 hours now.

I inherited a project from an employee who left; a projected checked out
from SCCM but no instructions on how to setup Ruby on Rails or what to
deploy etc so started googling around.

I found so many articles about the right way and the wrong way and some
were adamant that I listen to no one else, and after following those
instructions things still failed.

I think I have worked out most problems.

$ruby -v
reveals

ruby 1.9.2p320 (2012-04-20 revision 35421) [x86_64-linux]

When I attempt to hit an URL: http://localhost:8080/rcgi/Some.rb

I get in the output that a module ‘money’ is needed.

so I run
$sudo gem install money

this is the output I receive:

Successfully installed dbd-sqlite3-1.2.5
1 gem installed
Installing ri documentation for dbd-sqlite3-1.2.5…
Installing RDoc documentation for dbd-sqlite3-1.2.5…
ERROR: Error installing money:
money requires Ruby version >= 1.9.2.

WTF?

I just did a $ruby -v and saw that I had Ruby 1.9.2 installed.
Also why do I get these first two lines (everytime I run this gem
install money command?:

wtf>Successfully installed dbd-sqlite3-1.2.5
wtf>1 gem installed
wtf>Installing ri documentation for dbd-sqlite3-1.2.5…
wtf>Installing RDoc documentation for dbd-sqlite3-1.2.5…

If I run $sudo gem install money, I get those lines again. WTF?

How do I get ‘money’ installed? Why doesn’t money work with 1.9.3 or
1.8.7 for that matter?

sincerely,

J.V.

I’m not sure what’s going on but try running sudo ruby prog … When
installing gems with sudo ruby probably uses a different directory to
store your gems.
Most people here use rvm, rbenv or chruby to get over issues with sudo
and use ruby at user-level.

You should try one of these, to get through these annoyances once and
for all.

Note that in order to install sqlite under ubuntu you need sqlite
headers.

Best Regards,

ps. I use rvm but people at Ruby@freenode talk a great deal about rbenv
you should try it GitHub - rbenv/rbenv: Manage your app's Ruby environment
