Asp Forum - Ubuntu vs Ruby

Ruboids:

Ubuntu does truly throw-down, no? Ubuntu rules like Mandrake could have
ruled, and like we all know RedHat will _never_ rule, right?

Oh, and Ubuntu is a Debian, not a RedHat, right?

So why does this awesome Ubuntu make my Ruby experience totally suck?

Try this:

- install everything to do with ruby1.8, with Synaptic Package Manager
- run my mighty MiniRubyWiki
- the system can't find webrick (LoadError), which is supposed to be part
of the core library!

So that leaves me trying to build ruby-1.8.4.tar.gz, where I can't build
tcltk stuff (don't ask), or copying the important stuff (including YAML) out
of the ruby-1.8.2 folders.

Thanks for letting me vent. Please don't try to help, except possibly by
infiltrating a Ruby zealot into Ubuntu!

Try this:

apt-cache search webrick
apt-get install libwebrick-ruby

It's part of a long running problem with Debian. While there have been
some improvements, the Debian repackagers are unfortunately unwilling to
work with the Ruby developers to come up with a packaging system that works.

Thanks! for answering my question to the archives. I won't do it because I
don't want to disturb my current hack.

It turns out webrick is all raw source (yet another credit to Ruby - an
entire web server kit written in pure Ruby with no DLLs!), so I just copied
it up from ruby-1.8.2/lib.

Oh, then I had to get yaml, and hijack versions of strscan.so and syck.so.

Would your apt-get have sucked down syck.so?

Copying stuff like that is a bad idea. It's best to use apt-get, or at
the very least, to use ruby gems.

I did that - fetch all the pieces of the core with apt, then install
rails with ruby gems, even though the latest Ubuntu seems to have a
recent Rails.

8-0 you got gem working???!!!

Is all my irritation caused by Ubuntu uses --prefix=/usr where normal
programs default to --prefix=/usr/local ?

Anyway the demo with all these tools worked slick, so I no longer have a
reason to futz with versions. But reinstalling Ruby from scratch on the
morning of the demo was _rrreeal_ fun!

RubyGems works fine on my Ubuntu system, using the distribution of
RubyGems, no hacking required.

And yes, you'd have gotten syck.so if you'd just installed the rest of
the APT packages for Ruby.

No, I suspect all your irritation is caused by not using APT to install
the necessary software, and instead cobbling together a Frankenstein
monster out of different versions of Ruby.

I'd strongly suggest you blow away your current mess and:

apt-get install irb1.8 libreadline-ruby1.8 libruby1.8 libwebrick-ruby rake rdoc1.8 ruby1.8 ruby

You'll then have everything I have for Ruby development. Then download
RubyGems, and it should install with no problems.

Then learn to use Synaptic. Open it up, click Search, enter ruby as your
search term, and choose "name and description". Any time you need some
random bit of Ruby stuff, see if it's in that list before you go on a
scavenger hunt.

It'd be nice if the Ubuntu 'ruby' package included everything that's in
a normal distribution of Ruby, but again, that goes back to the Debian
packagers.

I recently installed Dapper on my laptop, and was able to get ruby and
gems on, but ri and rdoc aren't available. Any ideas?
