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.

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

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.

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.

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.

cheers,

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.
