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: 0) 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.

This is how rubygems is typically installed (by not supplying the --prefix option in step 4). But you do not have root access.

Actually, from testing, it'll be more like ${HOME}/local/rubygems/lib/ruby/site\_ruby/1.8 or some-such. > **···** > > On Dec 28, 2006, at 16:50, Eric Hodel wrote: > > > On Dec 28, 2006, at 16:30, Paul van Delst wrote: > > > > > Is there some other magical envar that I need to set so that ruby and rubygems play nice? > > > > You probably want to add: > > > > export RUBYLIB=${HOME}/local/rubygems > > -- > Eric Hodel - drbrain@segment7.net - [http://blog.segment7.net](http://blog.segment7.net) > > I LIT YOUR GEM ON FIRE! ---

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. cheers, paulv > **···** > > > On Dec 28, 2006, at 16:30, Paul van Delst wrote: > > -- > Paul van Delst Ride lots. > CIMSS @ NOAA/NCEP/EMC Eddy Merckx > Ph: (301)763-8000 x7748 > Fax:(301)763-8545 ---

You just needed to add rubygems to the $LOAD\_PATH. 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).

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. > **···** > > On Dec 28, 2006, at 17:45, Paul van Delst wrote: > > > Eric Hodel wrote: > > > > > On Dec 28, 2006, at 16:30, Paul van Delst wrote: > > > > > > > Or should I install rubygem "inside" my ruby install?

Yes, this is correct. I thought you were installing rubygems using the default (/usr/lib/ruby) installation, not your own. > **···** > > On Dec 28, 2006, at 18:05, Paul van Delst wrote: > > > Eric Hodel wrote: > > > > > > This is how rubygems is typically installed (by not supplying the --prefix option in step 4).
