Building ruby from source

I removed my older ruby package from my ubuntu, built ruby from source successfully. added the sym link from ruby1.8 -> ruby in /usr/bin/

however from the IRB I'm getting errors it can't find my gems? how do I fix this, I assume I need to define some environment variables?

irb(main):003:0> require 'rubygems'
LoadError: no such file to load -- rubygems
         from (irb):3:in `require'
         from (irb):3

Despite some of the kind suggestions from others, the particular file
rubygems.rb should be in

.../lib/ruby/site_ruby/1.8/

if Ruby and rubygems are both installed. Note that this is not the
gem binary, but rather the file which allows your program to load
gems.

The ... stands in for an installation path which varies from system to
system. But should be something like /usr or /usr/local on a Debian
based system. Actually self installed stuff should be in /user/local
IIRC so as not to collide with packaged stuff.

You can try to add the path to your current gems:

export PATH=/var/lib/gems/1.8/bin:$PATH

Apparently, if your compiled-from source Ruby cannot find "rubygems". :wink:

Most likely, installing RubyGems should be enough.

How did you remove Ruby? Using apt-get? Which options? Or by other means?

I am about 75% sure you have rubygems installed through Ubuntu. I bet if you do
'sudo apt-get remove rubygems' (I think that's right) you'll see what I mean. This
Debian distro of rubygems won't work with the source distro of Ruby (at least
not easily). You'll need to remove the one installed through apt and install from source
as mentioned above.

Right, I'm a little foggy here (It's been a while since I last touched any from of *NIX).

However, it seems that you now have a rather curious state for your Ruby.

For one, Ruby is split into several packages (ruby, irb, ruby-dev, libruby, ri; off the top of my head), and a couple of Ruby packages exit, too, most famously RubyGems.

However, each distribution (more or less), tweaks their offered packages to conform to the distribution's file system layout.

These tweaks are not necessarily identical to what a build from source provides.

So, it seems that your Ruby install is in an inconsistent state, where Ruby, and RubyGems don't "know" about each other, since they use different directories.

A solution would be to do a "sudo aptitude remove ruby*" to remove anything the distro installed, re-do "sudo make install" in your Ruby source directory, and then install RubyGems and your desired gems (it might be enough to monitor the filesystem, and see which directories "make install" and the RubyGems install create, and to copy your gems into this new directory.

Or:

You remove compiled-Ruby with the hopefully existing "make uninstall", and then reinstall Ruby from Ubuntu's repositories, and hope that fixes everything (it should).

Aside: A tool I found handy when installing from source is Checkinstall: http://checkinstall.izto.org/ allowing to introduce software compiled from source to a distribution's packet management system. :slight_smile:

As many possibilities as there are Linux distributions. :wink:

Usually, it is "/[var|opt]/lib/ruby/1.8/gems/". The particulars depend on your distribution.

Phillip,

thanks for helping out. A simple reinstall of rubygems and the gems is all that was needed to restore the state. (I was trying to avoid this being lazy).

RI is happy again, gems are being found with no issue.
