LoadError: no such file to load; specified gemset not used?

[ruud144]

hi list,

I use rvm for some time, but once in a while I encounter unexplainable
problems. I hope you can help me on this one. I use zsh. My problem is
that jruby seems to be unable to locate a gem while it is installed.

I have tried to create a short and complete example showing the
problem. I hope one of you can tell me what I am overlooking.
This output shows the problem:

$ mkdir rvm
$ cd rvm
$ echo "rvm use jruby-1.6.5" > .rvmrc
$ echo "rvm jruby-1.6.5@rvm" >> .rvmrc
$ cd /tmp; cd -
~/rvm

As you can see the net-sftp gem IS installed but I keep getting the
'no such file to load' message, and this happens too if I do not make
use of a gemset, but install the gem in the jruby-1.6.5 directory
itself.
I found out that if I do exactly the same but not using jruby-1.6.5,
but ruby-1.9.2 instead, it works without problem. Maybe it is
unrelated to rvm?

thanks in advance, Ruud

maybe you have JRUBY_HOME set or other environment variable?

hello mpapis,

not that I am aware of, below is an extract of my environment settings
in the shell.
Looks all right to me. What I find strange is that $GEM_PATH is very
clear about the location. I have tried a symlink in het gemsdirectory
to net-sftp-2.1.2 named net-sftp. That made no difference. The
LoadError stayed the same.

regards, Ruud

Hi group,
is it possible that the combination jruby/rvm leads to this kind of problems? I encounter this LoadError for most of the installed gems. For example a simple sinatra script fails with this message too:

$cat kna.rb
require 'sinatra'    
get '/' do
        redirect '/index'
end

$ruby ../utils/kna.rb
LoadError: no such file to load -- sinatra
  require at org/jruby/RubyKernel.java:1038
   (root) at ../utils/kana.rb:1
zsh: exit 1     ruby ../utils/kana.rb

/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- sinatra (LoadError)
        from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
        from kana.rb:3:in `<main>'
zsh: exit 1     ruby kana.rb

$ bundle show sinatra

the only thing I found in the output so far is very old rvm => rvm_version=1.10.0-pre

the current version is 1.20.13 - please update rvm, reinstall ruby, and try again
