Rubygems install problems (the old ubygems (LoadError) probl

Ruby
1

Hello,

I just did a complete re-install of ruby 1.8.5-p12 and rubygems-0.9.0
and I’m getting the
old sawhorse error:

ruby: no such file to load – ubygems (LoadError)

I’ve searched the newsgroup, but nothing seems to address the problem
I’m having (I
think). Here’s what I did:

  1. rm -fr’d my “ruby” and “rubygems” installation directories in my
    $HOME/local (I do not
    have root access to the computer in question). Also unset RUBYOPT.

ruby install

  1. Installed ruby 1.8.5-p12. No problems
  2. Modified my login script with:
    export PATH=$PATH:${HOME}/local/ruby/bin
    ruby and irb run fine.

rubygems install

  1. Specified where I want gems to actually go,
    export GEM_HOME=${HOME}/local/rubygemrepository
  2. ruby setup.rb config --prefix=${HOME}/local/rubygems
  3. ruby setup.rb setup
  4. ruby setup.rb install
    …
    Successfully built RubyGem
    Name: sources
    Version: 0.0.1
    File: sources-0.0.1.gem
  5. In login script added
    export GEM_HOME=${HOME}/local/rubygemrepository
    export PATH=$PATH:${HOME}/local/rubygems/bin
    and
    export RUBYOPT=“rubygems”

Now I want to install a gem (Bil K.'s funit) and I did:

gem install funit

and got the error:

ruby: no such file to load -- ubygems (LoadError)

And, of course, ruby and irb no longer work either (same error).

O.k., so what did I do wrong? After I installed rubygems I set the
RUBYOPT envar. But,
ruby can’t seem to find anything rubygem related.

Is there some other magical envar that I need to set so that ruby and
rubygems play nice?

Or should I install rubygem “inside” my ruby install? In:
${HOME}/local/ruby/lib/ruby/site_ruby/1.8/i686-linux ?
or
${HOME}/local/ruby/lib/ruby/site_ruby
or
??

I followed the notes I made last time I did this[*] and it worked then,
so I’ve screwed
something up somewhere; I just don’t know what.

Any help/info appreciated.

cheers,

paulv

[*] Said notes being a little sketchy, hence my starting from scratch
effort.

This tells ruby to put ubygems.rb under ~/local/rubygems.

  1. ruby setup.rb setup
  2. ruby setup.rb install
    …
    Successfully built RubyGem
    Name: sources
    Version: 0.0.1
    File: sources-0.0.1.gem

This puts ubygems.rb under ~/local/rubygems.

ubygems.rb is not in your $LOAD_PATH for ruby.

You probably want to add:

export RUBYLIB=${HOME}/local/rubygems

Or should I install rubygem “inside” my ruby install? In:
${HOME}/local/ruby/lib/ruby/site_ruby/1.8/i686-linux ?
or
${HOME}/local/ruby/lib/ruby/site_ruby
or

This is how rubygems is typically installed (by not supplying the –
prefix option in step 4). But you do not have root access. You just
needed to add rubygems to the $LOAD_PATH.

Hi Eric,

export RUBYLIB=${HOME}/local/rubygems

Well, I eventually figured out that I need
export RUBYLIB=${HOME}/local/rubygems/lib/ruby/site_ruby/1.8

Just specifying ${HOME}/local/rubygems didn’t work.

Or should I install rubygem “inside” my ruby install? In:
${HOME}/local/ruby/lib/ruby/site_ruby/1.8/i686-linux ?

This is how rubygems is typically installed (by not supplying the
–prefix option in step 4). But you do not have root access. You just
needed to add rubygems to the $LOAD_PATH.

This is going to make your eyes roll, but how does one add a root
subdirectory to
LOAD_PATH so that ruby searches recursively down? The only way I can
figure out how to
modify LOAD_PATH is to list every specific directory via the RUBYLIB
envar – which is
rather onerous.

An online search didn’t reveal anything clever.

Actually, from testing, it’ll be more like ${HOME}/local/rubygems/lib/
ruby/site_ruby/1.8 or some-such.

Hello again,

O.k., I removed my old rubygems install and did it again but without the
–prefix-dir and
everything is now honky dory.

From the rubygems user manual installation help, I assumed that a
“default” install would
always go to /usr/lib/ruby/etc… But it doesn’t - it gets installed
wherever ruby was
installed (at least, that’s what happened on my box).

Thanks for your patience.

cheers,

paulv

Yes, this is correct.

I thought you were installing rubygems using the default (/usr/lib/
ruby) installation, not your own.

You can’t, and you don’t really want this.

If you have lib/net/http.rb and recursively add everything you’ll end
up with the ability to require ‘http’ which may cause bad things to
happen like double loading.
