[LRUG] Rails/RVM path confusion

[Duncan Stuart]

I don't know if this is relevant, but the docs suggest you need to include
'use' before specifying the gemset when you're using the command line (but
not when scripting):

from command line: rvm --rvmrc --create use 1.9.2 at funky
for scripting: rvm rvmrc create 1.9.2 at funky

Do you definitely need to create a named project-specific gemset? If you
look in .rvm/gems/, has your @r1 gemset been created?

Are you sure your rails path is correct in your question? I'd have
expected .rvm/gems/<<something>>
rather than .rvm/rubies/<<something>>

Hope this helps.

Regarding point 2 - my understanding is that the rvm line you pasted adds
all the gemsets (.rvm/gems/) for the current ruby version (rvm current)
into your path.
